Abstract:

Describes a power transmission providing cushioned shock-absorption power flow from a drive member to a driven member. The transmission includes a gear pump wherein both the gear and gear housing are free to rotate the transmission also includes a recirculation flow path from the pump outlet to the pump inlet, said flow path comprising a metering valve that responds to pump outlet chamber pressure for progressively throttling the flow as the outlet chamber pressure rises. As the recirculation flow is throttled the pump gear and pump housing gradually lock together and thereafter rotate at approximately the same speed. Author
