Abstract

PURPOSE: To reduce the frictional force applied onto a movable shaft and improve the efficiency of the pump by constituting the pump so that the bending force and the torsion stress are not applied to a driving shaft.
CONSTITUTION: When a driving shaft 2 is rotated, the rotation is transmitted to a cylinder block 5 through a key 22 at the end part of the driving shaft 2, and a plunger 6 shrinks in correspondence to the variation of a gap between the plunger 6 and a cam ring 7, an operating oil being sucked, compressed and discharged through a valve ve plate 11. In this case the torsion stress based on a thrust of the plunger 6 applied to the cylinder block 5 and the contact friction between the plunger 6 and cam ring 7 is received by a bearing 21 through boss parts 20A and 20B.
