| 摘要 |
The present invention is drawn to a fluid gear coupling in which the lock up RPM between the drive member or power input shaft and the driven member or power output shaft is variable depending on the torque or power applied to the drive member or power input shaft. The present invention employs valves on the drive member which close off the exit ports of a pump disposed between the drive member and the driven member which are responsive to both pressure and centrifugal force. In the preferred embodiment of the present invention, check valves are provided in the main inlet ports of the pump along with auxiliary inlet ports so as to brake the device and prevent freewheeling upon deceleration.
