The invention solves the wiring! a linearized hydronettor in conjunction with a control non-reversible hydraulic generator and the control of logic hydraulic valves.

Dooud oo used for hydraulic wiring the hydraulic switchboards whose disadvantage lies in the demanding production, the necessity of considerable cleanliness of the working gear and the wiring is complex.

The above-mentioned disadvantages eliminate the circuit according to the invention, which has the fact that the return space of the combined linear hydraulic motor is directly connected to the discharge branch of the generator. the filling valve of the tank and discharging the valve of the quick-moving space of the konbiaovoný rectilinear hydronettor during the eucalyan iodine-hour interconnection of the aerobic port of the konbiaovonárannical hydronettor through the toggle valve and the throttle valve of the working valve.

The control valve of the reversing valve and the control valve of the ejecting valve can also be connected to the hydraulic control element.

Furthermore, the control valve of the valve can be connected to the throttle valve with the working space, while simultaneously disengaging the grooved space of the pivoted rectilinear hydronetter by switching the valve to the control valve of the charge valve.

By realizing the connection according to the invention, it achieves design simplification, cheaper production and reduced maintenance and maintenance.

In the accompanying drawing, there is shown the wiring of a well-connected rectilinear hydraulic motor 6, which is connected to the work space 2, a fast-moving prootor 6 and a return-prootor 6.

The circuit further comprises a filling valve 6, a throttle valve 6, a hydrogen generator 6 which is non-reversible, the reversing being achieved by a reversing vontilon 8. _}

The wiring further comprises a discharge valve 8, a bias valve 10, a hydraulic control element 11, a discharge branch 12, a relief valve 13, and a tank 14.

In the operation of the filling valve 8, the reversing valve 8, and the discharge valve 8, the operating space 17 of the filling valve 8, the actuator 54 of the reversing valve 8 and the space 16 in the inlet valve 8 are successively operated.

The working medium from the pump 5 exiting the discharge nozzle 13 can be further guided in three different ways.

a) into the groove space 6 of the pivoted straight-line hydraulic motor 6 through the orifice valve 8 with the filling valve 6 open, this connection corresponds to the rapid forward function.

b) into the return space 6 of the combined rectilinear hydronettor 6, with the filling valve 6 open; this connection corresponds to the reverse feed function.

(The physical condition for the force equilibrium implies that the surface area of the piston for the ryohlopoouv must be larger than the area of the backward displacement peak).

c) into the working space 2 of the pivoted rectilinear hydraulic motor 6 when the valve 8 is closed, this connection corresponds to the function of the working feedrate forward.
