FLUID PRESSURE PUMP MOTOR |
| 摘要 |
A fluid pressure pump motor includes a supply/discharge passage where both a hydraulic fluid pumped in to a fluid pressure pump and a hydraulic fluid discharged from the fluid pressure motor flow, and a variable valve provided in the supply/discharge passage to control the fluid path area of the supply/discharge passage. The variable valve reduces the fluid path area of the supply/discharge passage for simultaneously actuating the fluid pressure pump and the fluid pressure motor to be smaller than the fluid path area for actuating only one of the fluid pressure pump and the fluid pressure motor. |

1. A fluid pressure pump motor comprising:
a fluid pressure pump that is configured to supply a hydraulic fluid to a fluid pressure actuator; a fluid pressure motor that is configured to be rotationally driven by the hydraulic fluid reflowing from the fluid pressure actuator; a supply/discharge passage where both a hydraulic fluid pumped in to the fluid pressure pump and a hydraulic fluid discharged from the fluid pressure motor flow; and a variable valve provided in the supply/discharge passage and capable of controlling a fluid path area of the supply/discharge passage, wherein the variable valve reduces the fluid path area of the supply/discharge passage for simultaneously actuating the fluid pressure pump and the fluid pressure motor to be smaller than the fluid path area for actuating only one of the fluid pressure pump and the fluid pressure motor. |
