HYDRAULIC DEVICE WITH DESIGN IMPROVED RELATIVE TO ITS SWITCHING INTO OPERATING MODE Russian patent published in 2017 - IPC F04B1/107 B60K17/356 F03C1/247 

FIELD: mechanical engineering.

SUBSTANCE: device 1 comprises a casing 6, which forms the first assembly. The shaft 2 forms the second assembly. The first and the second assemblies are made with the possibility to freely rotate relative to each other. The cam 3 with multiple projections is connected to one of said assemblies, the first or the second, while rotating. It contains the distributor 51 and the distributor cover 52. The cylinders block 4 is mounted with the possibility of free rotation relative to said first and second assemblies. It comprises the coupling means with the other of said assembly, while rotating. The hydraulic device 1 comprises returning means tending to displace the cylinders block 4 with the purpose of its disengagement while rotating with said first and second assemblies. The distributor 5 is configured to provide the clutch of the cylinders block 4 while rotating with the other of said first and second assemblies at the pressure feeding. It can be used in vehicles.

EFFECT: ability to carry out the drive using the nearest driven motor with less effort, slip, wear and noise, and to prevent shock or pressure surges.
