The invention relates to engineering hydraulics and can be used as power sources for high pressure systems.

The purpose of the invention is to reduce the mass and dimensions of the multiplier.

The drawing shows a schematic diagram of a multiplayer.

The hydraulic multiplicator contains low pressure cylinder 1, high pressure cylinders 2 and 3 assembled in a common housing 4, low pressure and high pressure pipelines 5 and 6. In cylinder 1, a distributor 7 is installed, made in the form of a spool bushing with stop rings 8 and 9, a drive piston 10, support plates 11 and 12, springs 13 and 14. A piston 10 is installed to form two drive cavities 15 and 16 of low pressure . The low pressure chamber 17 is connected through the openings 18 and 19 to the drive cavities 15 and 16, and the chamber 20 through the channels 21. The hydraulic camshaft rods, made in the form of plungers 22 and 23, are installed in the housings 24 and 25. The working cavity 26 is high the pressure is connected through a check valve 27 to a pipe 6 connected to the discharge line (not shown), and through the valve 28 and channel 29 to a cavity 16, which is connected to the vane pump (not shown) through pipe 30. The holes 31 and 32 in the cylinders 2 and 3, depending on the position of the distributor 7, connect the chamber 17 to the subnet 15 or the chamber 17 to the cavity 16.

The multiplier works as follows.

The drive medium is pumped by a vane pump through pipe 5 into chamber 17 and through holes 31 and 1 fills cavity 15, piston 10 moves to the right (according to the drawing). At a certain pressure value, the valve 27 is activated, and the working fluid through the valve 27 enters the pipeline

6. From the cavity 16 through the channels 21 of the cylinder 3, the working fluid is pushed into the chamber 20 and further to the vane pump. When the piston 10 moves, the support plate 12 abuts against the stop ring 9 and moves it and the distributor 7, opening the opening 32 and closing the opening 31. Filling the cavity 16, the working fluid simultaneously fills the working cavity 26 through the valve 28. The cycle then repeats.

Thus, the integrated spool valve provides an opportunity to achieve automatic continuous operation while reducing the weight and dimensions of the hydraulic multiplier.
