Abstract
PURPOSE: In a vane pump used in a power steering device, to improve the volume efficiency and to prevent the abrasion and the burning of the rotor contacting face by providing proper clearance between the side plate and the rotor.
CONSTITUTION: When the delivery pressure of pump is increased, an endcover 12 is deformed by the pressing force functioning on the face contacting against a rotor 22 of a side plate 16 to increas the clearance between the side plate 16 and the rotor 22, but the delivery pressure is guided to a pressure operating chamber 40 formed between the side plate 16 and the endcover 12 thereby the pressure fluid will function on the back of the side plate 16 thus to contact the side plate 16 tightly against the end face of a cam ring 14. Consequently the clearance between the side plate 16 and the rotor 22 is prevented from increasing thereby the abrasion and the burning of the sliding face can be prevented.
