Abstract
A variable output vane pump for use with an automotive automatic transmission. At least one pressure chamber is formed between the circular bore of a housing and the outer circumference of a ring by means of at least one seal pin which is fitted in the axial groove formed in the ring circumference and which is opened in the housing bore. The ring is urged by the action of a spring, which is fitted in the housing, in a direction opposite to the pressure to be built up by the pressure chamber. An elastic member is fitted in the bottom of the axial groove to urge the seal pin both toward the housing bore and at the same time toward one of the side walls of the axial groove. The urging direction of the elastic member and a tangential line, on which the seal pin is tangential to the housing bore, are angularly positioned at an acute angle with respect to each other.
