Patent ID: 8596186

Claim:
A radial piston motor ( 1 ), in which a predetermined displacement volume can be set by a hydraulic eccentric adjustment via an eccentric element ( 2 ), with an adjustment device by which, to position the eccentric element ( 2 ), the adjustment device can be acted upon by pressure medium via a shuttle valve ( 5 ), wherein the adjustment device comprises at least one actuating piston ( 19 ) that can be acted upon on opposed sides via an adjustment cylinder ( 3 ), the adjustment cylinder ( 3 ) has a first pressure chamber ( 7 ) which is connected to a first supply line ( 9 ) for setting a smaller displacement volume while a second pressure chamber ( 8 ), of the adjustment cylinder ( 3 ), is connected to a second supply line ( 10 ) for setting a larger displacement volume, the first and the second supply lines ( 9 , 10 ) are connected to one another by a connecting line ( 11 ), the shuttle valve ( 5 ) is connected to a flow valve ( 4 ) and, in a first switching position of the flow valve ( 4 ), the first supply line ( 9 ) is connected to the pressure medium by the shuttle valve ( 5 ) and the second supply line ( 10 ) is connected to a collecting tank ( 17 ), and in a second switching position of the flow valve ( 4 ), the first supply line ( 9 ) is connected to the collecting tank ( 17 ) and the second supply line ( 10 ) is connected to the pressure medium by the shuttle valve ( 5 ), and a connecting throttle element ( 12 ) is arranged in the connecting line ( 11 ).
