Kind Code:
B2
Abstract:
PURPOSE:To respond to various controls in a simple and compact composition by holding a pump cylinder casing rotatable while fixing and holding a motor cylinder casing, and linking the pump cylinder casing and the motor cylinder casing. CONSTITUTION:When a pump main shaft 12 is driven, the released oil from a hydraulic pump P is fed to a hydraulic motor M to drive the motor M. The reseased oil amount from the ump P responds to the relative rotation of the shaft 12 and a pump casing 11, and since the casing 11 is held rotatable and linked to a motor shaft 51, the released oil amount from the pump P is proportional to the rotation frequency difference of the shaft 12 and the shaft 51 when the capacity of the pump is constant. In this case, the capacity of the pump is proportional to the reciprocating stroke of a pump plunger 22, and this reciprocating stroke can be controlled variable by rotating a lever 18 to regulate the eccentric distance L3 of an eccentric collar 15. Therefore, the control can be carried out only by rotating and controlling the lever 18.
