Abstract

PURPOSE:To improve the suction efficiency of a vane pump and prevent generation of cavitation and vibration noise by reducing the width of an oil feeding passage narrower in the lower part and forming the lower edge to be closed and preventing the generation of the irregular stream in the vicinity of suction ports. CONSTITUTION:The oil which flows from a suction tube 40 flows down, divided right and left in an oil feeding passage 23, and flows into suction ports 27, 27 and 27', 27' which are formed on the both sides of a pressure plate 24 and a thrust plate 25, and is sent into a cam ring 22. The width of an oil supply passage 26 is reduced narrower in the lower part, and the width of the part passing the suction ports 27 and 27 is exceedingly reduced, and the lower edge is closed. Therefore, generation of the irregular stream of the oil in the vicinity of the suction ports 27, 27 and 27' 27' is prevented, and the suction efficiency is improved, and generation of cavitation and the vibration noise of the pump can be prevented.
