The invention relates to a device for converting kinetic or potential energy of a floating object, the energy of compressed air, its accumulation and subsequent use.

Known energy-accumulating device hoisting mechanism comprising a housing with installed power spring and the piston, through which the pusher exerts control on the braking mechanism, as well as a small working chamber (Martynov R.A. KAMAZ Vehicles. The operation and maintenance. Rahmaninov, Vautrinot, Waspromoted. - M.: Nedra, 1981. - 424 S., see str).

Known energy-accumulating device hoisting mechanism has a relatively complex structure, small volume cumulative working fluid that does not allow him to use hydraulic hoisting mechanism and to modify the pressure of the working fluid in the working chamber.

Known energy-accumulating device hoisting mechanism comprising a housing, a valve for by-pass air supply and discharge lines (Kaverin SV Course and diploma design, hydraulic self-propelled machines: Uch. a manual for students / Swivelin. - Krasnoyarsk: PEAK "Offset", 1997. - 382 SIL., see str).

Known energy-accumulating device p is djenno-transport mechanism has a limit of the accumulated energy worker body size, not exceeding energy moved or produced by the power plant. As a consequence, if necessary technological operations with large energy consumption, for example, high pressure working fluid requires an additional energy source.

The technical result consists in increasing the energy of the working fluid in the energy-accumulating device.

The technical result is achieved by including in the energy-accumulating device hoisting mechanism comprising a housing, a valve for by-pass air inlet and outlet piping, heater, made for example in the form of a burner with a supply of fuel and ignition system.

The proposed construction of energy-accumulating device hoisting mechanism with a supply of heat allows you to remove the restriction of the accumulated energy of the working fluid amount, not exceeding the energy moved, or produced by the power plant, and enables you to perform subsequent technological operations with large energy consumption, for example, high pressure working fluid, without additional energy source, such as a power plant.

In the patent and scientific literature is similar to the design of energy-accumulating the disorder hoisting mechanism we have not identified.

The drawing shows a structural diagram of energy-accumulating device hoisting mechanism with heat supply (supply and discharge lines not shown).

Energy-accumulating device hoisting mechanism with a supply of heat includes a housing 1 with it working body 2 and the air space 3 into which you installed the heater 4 and the valve for the bypass air 5.

Energy-accumulating device hoisting mechanism with a supply of heat is as follows.

The working body 2, the injected power plant through pipelines (not shown), enters the energy-accumulating device hoisting mechanism, where its energy is stored in the form of energy compressible air space 3. Next, compressed air space is heated by a heater 4, made for example in the form of a burner with a supply of fuel and ignition system that leads to a change in temperature of the air space 3, which, in turn, leads to increased pressure of the working fluid 2. When the maximum pressure activated valve for bypass air 5, after which the process of discharge of the working fluid 2 stops. Valve for bypass air 5 is designed for Ogre is icene pressure of the air space and changes its volume.

This design of energy-accumulating device hoisting mechanism allows you to remove the restriction of the accumulated energy of the working fluid amount, not exceeding the energy moved, or produced by the power plant, therefore, allows you to perform technological operations with large energy consumption without additional energy source.

Energy-accumulating device hoisting mechanism comprising a housing, a working body, inlet and outlet piping of the working fluid, air space, and a valve for by-pass air, characterized in that the upper housing is installed heater, made in the form of a burner with a supply of fuel and ignition system, and the heater is arranged to change the temperature of the air space, resulting in increasing pressure of the working fluid, and a valve for by-pass air is arranged to limit the pressure of the air space and changes its volume.
