The invention relates to shipbuilding, and specifically to equipment for supplying air to the diesel engines and the ventilation system of diesel which includes a feeder air. This device is used to supply air to the compartments only at periscope-depth depth SQ. The design feature of this device is that it has great height and is located in the fence retractable devices /LOW/ and in compartment durable housing /PC/. In ECA are retractable air shaft /mast/ s installed on it the float valve and the upper part of the stationary air shaft, and the lower part of the stationary air shaft through wares on the PC goes into the Bay PL. Device via a fixed shaft in the middle and is attached to the chair of the PC, and in its upper part to LOW (prototype, see "Device submarines" C. N. Prasolov, M. B. Amitin, page 274, Voenizdat, 1973).

For lifting retractable air shaft of the device is provided with a platform consisting of a body, mounted on PC, and is located inside the housing of the rolling stock, the upper end of which is connected with the lower end of the retractable mast. The connection of the stem with the body of the platform is sealed with a package of rubber sealing rings, and connecting rod with a fixed shaft seal. When lifting in the case of the platform served the working fluid from the hydraulic system. The spindle extends from the body and raises the slide out mayh in the still air of the mine. Lowering occurs under the weight of the retractable mast and other moving parts. For protection against accidental lowering of the retractable mast in the highest position is placed on a special Cam stopper with manual drive out of the Bay PL.

Disadvantages described RDP device is as follows: 1. The device provides a supply of air only at periscope-depth the depth of the SUBMARINE, and surface position air is supplied through sahtu supply air to the diesel engines made in the form of partitions in the housing POLICY, through a separate pipeline with zahlopal.

2. Retractable air shaft (mast) is made in the form of a circular tube, which has a large hydraulic resistance and the resulting hydrodynamic overload is not allowed to increase the speed of DPS more than 8-10 knots. In addition, all pipe leaves a very visible foam trace on the surface of the water, which unmasks SQ. Air shaft (mast) is made of steel and corrode and therefore to prevent and reduce friction, it should always be lubricated. In addition, air shaft (mast) is moved in the bronze bushings that does not allow you to put on its outer surface radioparadise cover to protect from detection pie size and weight and, located in the LOW and in the Central compartment, substantially restrict it. For the passage of a fixed mine air into the compartment in a rugged necessary Waris large size and weight, and in the case of the platform durable and rigid Foundation. Mounting stationary shaft to the housing POLICY complicates the installation of the device and does not preclude misalignment as a result of exposure to the device housing POLICY.

The present invention is the creation of a single feeder air consumed by the running diesel engines and ventilation system as in surface position and periscope-depth the depth of the SQUARE, with the mast (retractable air mine) well streamlined profile with a software application on its outer surface radar absorbing coating and fully located in LOW.

The task is solved by the fact that in the known device, an air supply containing reference-guide apparatus with retractable mast with a detent and float valve, hydraulic hoist reference-guide device is made in the form of farm and railing posts installed on the foundations of a solid body, with retractable mast in its lower part provided with shoes that they can move their p water the upper part of the farm is equipped with a bracket, which is fixed to the pipe of the intake air, coupled with by means of the reducer with retractable mast, and the mast stopper is equipped with a hydraulic actuator and the hydraulic hoist is installed inside retractable mast.

In addition, the mast of such devices is well streamlined in the water flow profile and the outer surface of the mast and float valve has a protective radar coverage. The invention is illustrated by drawings.

In Fig.1 shows a General view of the device with a raised mast.

In Fig.2 shows a General view of the device with lowered mast.

In Fig. 3 depicts a cross-sectional profile of the mast and supporting-rail farm.

The outlet air to the diesel engines consists of the following main components: retractable mast 1 with float valve 2 at its upper end and fixed: reference-guide farm 3 with the tube receiving air 4, the stopper 5 with its drive - hydraulic machine 6 and the platform 7.

The mast 1 is used to supply air at periscope-depth the depth of the SQUARE and is a tube with a well-streamlined cross-sectional profile and the version under consideration has the form of a double Sega 8, which set forth the liners 9 bearings and which mast glides racks farm 3. The liners 9 is made of a material with a low coefficient of friction and it does not require lubrication. In the center of the mast installed pipe 10, is rigidly by means of ribs connected with the outer shell of the mast, which is the platform 7. Between 8 shoes through the adapter to the mast rigidly attached to the pipe 11 connecting the mast pipe with the intake air 4. On the outer surface of the mast and the hull of a floating valve cover coaming caused radioparadise floor /PSC/. To drain water after lifting mast and filling with water when lowered into the bottom of the mast there is a hole.

Reference-guide farm 3 provides for movement of the mast 1 when lifting and lowering and perceives the hydrodynamic load from a stream of water flow over the mast. Farm 3 consists of four support legs 12 interconnected transverse and longitudinal ribs /Fig.3/. To the posts 12 through electrically insulating plastic 13 are attached to the rack rails 14, made of titanium, which slide bearings mast 1. At the top of the farm includes a bracket, which is fixed to the pipe of the intake air 4; bottom farm snapshotting of titanium and is used to supply air to surface position PL, in the upper part it has the air hole, and the bottom of the pipe 4 terminates in a flange for connection to the air supply line.

The stopper 5 a bracket attached to the posts 12 and serves to hold the mast in the raised position. The main part of the stopper 5 is a stopper pipe 15, which in the lowered position of the mast 1 is a vertical position, and after lifting mast hydromachines 6 through the rod 16 is rotated in the bearings of the bracket in a horizontal position under the bottom of the mast to hold. As a jammed hydromachine is pass it crank for the dead point, even when a sudden pressure drop in the hydraulic system of the stopper pipe will not fall and will hold the mast in the raised position. Through the stopper pipe is also water discharged from the mast after her recovery, what it is made hollow. In horizontal position the hole in the stopper inlet aligned with the hole in the bottom of the mast, and the stopper socket connected to the pipe connected to the outlet pipe.

Hydromachine 6 standard design in the extreme positions of the pistons is now the pass of the crank through the dead point and are selected from conditions ensure neobhodimosti /height/ installed in the mast. The platform 7 is composed of rolling Zilina 17 attached to the bottom of the mast 1, and the fixed shaft 18, through the support ring attached to warichu hull.

The device operates as follows.

In surface position PL /Fig.2/ the working fluid from the hydraulic hoist merged, the mast 1 with transition pipe 11 is omitted, the air hole is open and the air through the pipe 4 flows through the air supply line into the Bay.

At periscope-depth the depth of a SUBMARINE to mast lift the rod 18 of the platform from the hydraulic system is supplied working fluid, its pressure cylinder 17 raises the mast 1 to lock the nozzle 11 in the cover of the suction pipe 4 and the bracket farm 3. Then hydromachines 6 through the rod 16, the stopper pipe 15 is rotated to a horizontal position under the bottom of the mast is removed and the pressure of the working fluid in the hydraulic hoist and mast sits on the stopper pipe 15. After PL will be on the depth at which the float valve is located above the water level, the water discharged from the internal cavity of the mast 1, the air intake pipe 4 and the air supply line through the drain pipes and the device is ready to air in SQ. When navigating a SUBMARINE at periscope-depth the depth of a small kolichestva and socket 11 and discharged through the drain pipe.

For lowering the mast hydromachines 6 stopper-tube 15 is rotated to the horizontal position, the mast through the hole in the bottom is filled with water and lowered to lock the shank of the cylinder 17 of the platform in the support ring shaft 18 on Varese PC. When this weight retractable mast 1 and the water pressure is additionally pressed sealing rings than it is securely sealed hydraulic chair lift water from entering the hydraulic cavity and Waris water from entering the compartment.

Calculation of noise and model tests of the mast streamlined profile showed that the proposed device can be used to speed VL of up to 20 knots at sea state up to 5 points.

Reference-guide farm considered design allows the use of retractable mast, streamlined profile that is applied to its outer surface and the outer surface of the float valve stealth coating, which greatly increases stealth SQ. The farm does not have attachment to the body LOW, and is attached only to a sturdy body that not only simplifies the mounting of the device on the SQUARE, but also eliminates the violation of the centering device from exposure to it through fastening to the case of LOW strain caused by the OS is Using the rotary stopper pipe with remote hydraulic drive allows you not only to automate the operation of raising and lowering the mast, but to make them easier and faster. For example, for lowering the mast just enough to shift the stopper pipe in a vertical position, which is essential for short-term immersion PL.

The device having a retractable mast with transition pipe and air intake pipe, provides the air supply as at periscope-depth depth and in surface position PL. This allows you to abandon the pipeline surface air supply with mine and zahlopal.

Installation of the platform inside the mast allows almost to halve the height of the device and fully place it in LOW, and the compartment is located only hydromachine drive the stopper. This reduces the constraint of the Central compartment, excludes foundations of the platform and chair under stationary air shaft having large dimensions and mass and time-consuming to manufacture and Wake in a robust housing.
