Distribution block contains installed in a single to use 1 spring-loaded check valve 2 and the three-position two-line distributor 3, 4, 5, each of which has a spring-loaded manual valve with the control chamber, the piston and rod are made interoperable end of the rod with the saddle that separates the input and output of hydroline the relevant distributor 3-5 in the case of 1 block. Valves distributors 3-5 installed in the housing 1 parallel to the non-return valve 2 (to reduce the size and simplify the mounting block).

In the housing 1 has three channels 6, 7, 8 supply, three channels 9, 10, 11 drainage and drainage channel 12, which is connected with a spring cavities 13, 14, 15 of the valves 3, 4, 5. The dispenser 5 is made normalizability and is spring-loaded against the side of the piston (not labeled), and its control rod cavity 16 is connected with the outlet check valve with piston 2 and the control cavities 17, 18 of the other two made normalroutine valves 3, 4, respectively, each spring from the stem (not labeled). The first supply channel 6 of the housing 1 is connected to the input of the check valve 2, the output of which is connected to the first channel 9-of-way and with the input hydroline first valve 3 connected to the output hydroline with the first drainage channel 9 of the housing 1.

The second supply channel 7 and the third channel 11 drain connected through the valve 20, i.e. may be communicated to or divided among themselves. On the second drainage channel 10 has an additional valve 21. The unit is equipped with expander 22 for separation of suspended and dissolved air, the upper part of which are connected by pipes (not labeled) with a third channel 11-of-way, and the bottom with the third supply channel 8 of the housing 1 unit made in the form of flow-through tank with a cross-section greater than the cross-section of the connecting piping at least 10 times.

In the drawings, figure 2-5 arrows show the direction of flow of the working fluid in the operating modes.

In the scheme of figure 6 indicated impeller (centrifugal) pumps 23, 24, the tank 25, the tank 26, 27 consumer (for example, a heat exchanger or turbine), the valves 28, 29, 30, 31, intended for maintenance of the pump 24, and the pointers 32, 33 level in the tanks 25, 26. The pump 23 is connected by suction directly to the channel 9, and the injection - to-consumer 27 connected to the output channel 7. The pump 24 is connected by suction directly to the tank 25, and the outlet channel 6. Channel 10 through the valve 21 may be connected with the tanks 25, 26 (the last is at a nominal level, above which is arranged overflow into the tank 5). The upper portion of the expander 22 is connected to the tank 26 above the maximum liquid level for admission of air released during the expansion of the fluid stream in the expander 22. The valve 12 is connected to the tank 26 at the lowest level in order to secure the filling of cavities management distributors 3-5 working fluid. This schematic diagram of the hydraulic system, which can be used to block distribution is preferred, but not required.

The distribution block is as follows.

The pump 24 when enabled, takes the working fluid from the tank 25. The valve 31 is open whenever the system is turned on. When the pump 24, the working fluid is supplied to the supply channel 6, the check valve 2 is opened, the pressure in the cavity 16 to 18, and distributors 3-5, overcoming the force of springs are moved. When the valves 3, 4 are closed and the valve 5 is opened. If the valve 21 is closed and valve 20 is opened (figure 2), the working fluid from the supply channel 6 is supplied under pressure from the pump 24 into the channel 9 of the bend and through the dead pump 23 in the consumer 27, and returns to the locked valve 21 channel 7 inlet and flows through the valve 20 and the expander 22 in tank 26 to fill it in. When this happens filling hydrocracy consumer 27 and the tank 26 of the working fluid. After filling the tank 26 to the nominal level) the individual may be discharged from it into the tank 25. In the process of filling can be made, if necessary, interruptions to refill the tank 25 (if the volume of the tank 26 of tank volume 25).

In the expander 22 there is a sharp decrease in the fluid velocity and the release of dissolved air.

Then, if the valve 20 to be closed and valve 21 to open (figure 3), the working fluid is returned to the supply channel 7 and flows through the valve 21 into the tank 25, providing a working circulation through the consumer 27 and the tank 26 performs the function of make-up, providing compensation for temperature changes of the fluid.

If the resistance hydrocracy increased (for example, when severely reduced ambient temperatures, for example below minus 30° (C), and simultaneously pumps 23, 24 when the condition of the valves 3-5 and valves 20, 21 shown in figure 3, and the working fluid is supplied under a total pressure of the pumps 23, 24 in the consumer 27, and returns to the tank 25.

In the mode corresponding to figure 4, only the pump 23. The pump 23 when turned on takes the working fluid from the tank 25. When the pump 23 and the check valve 2 is closed, the pressure in the cavity 16 to 18 is not served, and distributors 3-5 are in their normal positions, determined by the adjustment of the springs. When the valves 3, 4 are opened, and the valve 5 is closed. If the valve 21 is opened and the valve 20 is closed (figure 4), working idcast, coming into the supply channel 7, is fed into the channel 11 of the challenge, then, through the expander 22 in the supply channel 8 and through the channel 9 of the outlet pressure of the pump 23, bypassing the idle pump 24, the consumer 27, and returns to the suction of the pump 23. The tank 26 through the expander 22 performs the function of charging amount.

Thus, the effective distribution block and expanded Arsenal blocks distribution.

This expanded functionality to ensure it works, in at least three modes of supply of the consumer and filling tanks and hydraulic systems with redundancy of pumps, i.e. alternating engagement of either of the two pumps, the second pump can be switched off to conserve the resource or malfunction, or both pumps simultaneously in order to secure the power of the consumer in the temperature range ±50°With (changing the hydraulic resistance of the hydraulic system in a wide range), providing compensation volume expansion/compression of the fluid and remove dissolved air. In block uses the simplest valves valve type, providing maximum tightness separation of inlet and outlet (in a pair of valve-seat) and placed in parallel to maximize the volume of Diego housing and ensure maintainability (access repair) failure of any of the distributors.
