Abstract
PURPOSE: To simplify the entire construction of the pump in a compact size by providing an eccentric part in an input shaft of a volume variable pump and arranging a piston connected to a controller in this eccentric part.
CONSTITUTION: There is provided the eccentric part 4 in the input shaft 1 of the volume variable pump, and there is provided the piston 8 adjacent this eccentric part 4, the cylinder chamber 9 of which is connected to a tank 16 through a check valve 14 and also connected to the controller 17 through another check valve 15. In this arrangement, a single piston can constitute the auxiliary pump for activating the controller 17, thereby simplifying the entire construction of the pump in a compact size.
