Abstract

The invention allows to expand the functional capabilities of the hydraulic motor. In the housing 1, the channels (K) 2, 3 are provided with liquid inlet and outlet. The shaft 4 with the rotor is mounted in bearings 6. The plunger 7 is located in the additional cavity 8 made in the housing 1 and is equipped with a seal 9. The plunger 7 is axially movable and interacts with a screw 10 made at the free end of the shaft 4. The cavity 8 is connected with K 2 and 3, K 11 and 12. In K 11, a check valve 13 is installed, in K 3 - a check valve 14. By moving the plunger 7 at a constant flow rate of the working fluid, different speeds of the shaft 4 in the opposite of 1x naiipaBJie are provided. in- x. 1 il.

The invention relates to mechanical engineering, in particular to hydraulic assemblies, and can be used in various areas of the national economy.

The aim of the invention is to enhance the functionality by providing different speeds of shaft rotation in opposite directions at a constant flow rate of the working fluid.

The drawing schematically shows the motor, section.

The hydraulic motor includes a housing 1 with channels 2 and 3 for supplying and discharging the working fluid, a shaft 4 with a rotor 5 installed in the support B, a plunger 7 located in the additional cavity 8 made in the housing 1 and fitted with a seal 9. Plunger 7 is installed axial movement and interacts with the screw 10, made at the free end of the shaft 4. An additional cavity 8 is associated with

When the hydraulic distributor is switched to the second position, the working fluid is supplied to the hydraulic motor through channel 3, while the rotor 5 vra, moves in the opposite direction and the plunger 7 moves

- inside the groove. Part of the working fluid from the cavity 2 through the channel 12 is fed to the rotor 5, which leads to an increase in the frequency of rotation of the rotor 5.

In this way, with the same supply of working fluid to the hydraulic motor, the latter rotates in different directions with different frequencies.

Invention Formula A hydraulic motor comprising a housing with channels for supplying and discharging working fluid, a shaft mounted in bearings, covers and seals, differing in meters that, with chains 2 and 3 of supplying and withdrawing channels 11-20 for expanding functional possibilities and 12. In addition, the hydraulic motor is equipped with the surroundings by providing different speeds rotation of the shaft in opposite directions at a constant flow rate of the working fluid, the hydraulic motor is equipped with a plunger. a valve 13 installed in a canal, 10 II and a check valve 14 located in a drip 3, as well as a hydraulic distributor 15 that changes the direction of flow 25 installed in an accessory fluid in the housing through the hydraulic motor. -the movement and interaction with the winery. made on the free end of the shaft. When supplying the working fluid in position and check valves, one of which SRI hydrodistribution; 1, shown installed in the supply and discharge channel of the working desk, the rotor 5 rotates, and at the same time rotates 30 liquids and another - in screw 10 is also pulled out. Plunger 7 with this housing additionally m channel, is connected from cavity 8, frequency of rotation of the additional housing cavity from the motor shaft to the supply and removal of the working fluid. When the hydraulic distributor is switched to the second position, the working fluid is supplied to the hydraulic motor through channel 3, while the rotor 5 vra, moves in the opposite direction and the plunger 7 moves inside the groove. Part of the working fluid from the cavity 2 through the channel 12 is fed to the rotor 5, which leads to an increase in the rotation frequency of the rotor 5. Similarly, with the same supply of working fluid to the hydraulic motor, the latter rotates in different directions with different frequencies. 15 Invention Formula
