Description

FIG. one

The invention relates to mashimostroopiyu, in particular to engines that operate on the basis of electrohydraulic effect,

Known electrohydraulic d-chagel (avt.sp. USSR № 629356, class, F 03 C 3/00, 1977), containing the case with channels for supplying and discharging the working medium of the torsion cover of the cover with the formation of tangential parabolic chambers, a profile mounted rotor with lugs and a retaining tank with a liquid, with electrodes placed on each chamber and on the protrusions of the rotor / The engine is operating due to shock waves arising from the electrical discharge between the electrodes in the working environment.

However, there is a considerable period of time between shock waves so that the engine can work reliably.

Also known is the engine 1, comprising a housing with working chambers located in the RPD along the axis of rotation of the rotor with protrusions placed on it along a screw line n several visits, i.e. each working chamber of the housing corresponds to several protrusions on the rotor, electrodes and a podzodz system of the working fluid in the form of a water collector connected in series from the bottom of the housing, a pump, a hydraulic accumulator and. distribution disc on the rotor with radial windows.

The disadvantage of this engine is that, due to the one-sided arrangement of the working chambers of the housing, the rotor is under one-sided load and has a large area of tight contact with the housing, when there is no effective drainage system for the gas and liquid.

The purpose of the invention is to increase the reliability of the engine.

The goal is achieved by the fact that in an engine containing a housing with working chambers, the rotor is g; the form of discs with ledges located along a helical line in several passes, as well as a system for supplying the working fluid, connecting keys that are successively interconnected to a water collector, a pump, a hydraulic accumulator, a distributor and supply lines with drop valves, the housing chambers are centrally symmetrical in the rotor's rotation plane, in the Pippunspy disks, the diversion channels connecting the steps of the ledges with the peripheral surface of the disks and arranged with the possibility of periodic overlapping of these zones

contact with the housing, with each disc provided with a central distribution disc with cams arranged to interact with the corresponding inlet valves, and in each working chamber of the housing there are check valves arranged to separate the cavity of the chamber.

Ne figure 1 shows the proposed movement, cross section; figure 2 is the same, a vertical section (section aa in figure 1).

Electro-hydraulic motor includes body 1 with working chambers 2,

5 rotor 3 with projections 4 and branch ducts 5.

For each disc of the rotor 3 is installed a distribution disc 6 with cams, with which it acts on the inlet valve

0 7. Both the rotor disks 3 and the distribution disks 6 are mounted on a common shaft 8. The inlet valve 7 communicates with the working chambers 2 via line 9 and 10, and through line 11 the valve 7 communicates with

5 by means of a hydroaccumulator 12, which is fed by the pump 13 with working fluid from the sump located at the bottom of the housing 1,

. The working chambers 2 are equipped with electrodes 14 and check valves 15, protecting highways 9 and 10 from the shock wave. On the shaft 8 there is a flywheel 16 with a ring gear for starting the engine from the starter. The engine works as follows.

The working fluid from the hydroaccumulator 12 through line 11 is constantly under pressure enters the inlet valve 7. When it is opened with the cam of the distribution disk b, the fluid through the lines 9 and 10 enters the working chambers 2, and the liquid displaces the spent fluid from them gases through the exhaust channel 5, which is not yet blocked in the zone of contact of the rotor disk 3 with the housing 1, at the moment channel 5 closes and the working chamber is filled with medium, an electric discharge is applied to the electrodes 14. The shock wave arises from the rotor 3 housing 1, and

On the last day, the shock waves in the other chambers cause the rotor 3 to rotate.

Figure 2 shows the moment of electrical discharge in one chamber 2 and the moment of filling the other medium 2 with the working medium.

5 engine, the waste medium is discharged into the catchment basin, from where it is fed again through the pump 13 to the accumulator 12.

Small size, reliability and ecological safety make it possible to use the invention several

widely as stationary equipment and transport.
