Abstract
PURPOSE: To contrive to make the pump small by forming grooves on side faces which come in sliding-contact with a casing and a pump gear of a cover, making an influence of a centrifugal force by the pump gear of a liquid induced from the intake to the side faces comparatively small and increasing a peripheral speed of the pump gear.
CONSTITUTION: The grooves 4 and 5 are formed on the side faces 1a, 2a coming in sliding-contact with the casing 1 and the pump gear 3 of the cover, and the large diameters 13 thereof respectively are made smaller than the outer diameter of the pump gear 3 and the small diameters 14 are made smaller than a gear bottom diameter. Whereby since the liquid induced from the intake 9 to the side faces 1a, 2a can make the influence by the centrifugal force of the pump gear 3 comparatively small, the peripheral speed of the pump gear 3 can be increased in large, and accordingly, the pump can be made small and low cost. Further, the grooves 4, 5 are formed at the positions corresponding to two times the norma-pitch of the pump gear 3 from a position 11 where the teeth of the pump gear 3 are released at a discharge port 10 of the casing 1, thereby enabling a volumetric efficiency of the pump to be prevented from falling.
