Abstract

PURPOSE:To prevent the occurrence of cavitation by forming a passage for connecting the fluid introducing port and the introducing-out port of a housing and providing a check valve which permits only the flow of fluid from the introducing-out port side to the introducing port side. CONSTITUTION:A working fluid flows into a hydraulic motor 3 and the working fluid in an operating chamber 16 flows into a connecting passage 50 causing a ball valve 52 to be moved and seated on a seat part 51 due to its fluid pressure. Even if negative pressure is generated in the operating chamber 16 due to the overrun of the hydraulic motor 3, the working fluid on a low pressure side flows into the connecting passage 50 causing the ball valve 52 to open on receiving its fluid pressure. Thereby, the low pressure working fluid in the connecting passage 50 is fed into the operating chamber 16 which becomes negative pressure, suppressing the occurrence of cavitation on the flow-side side of the motor.
