Title: Vehicle oil pump
Inventor: HONDA HIROYASU
IPC: F04C2/10
Filed: 2009-09-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide an internal gear-type vehicle oil pump with reduced rotational resistance.  <P>SOLUTION: A driven gear 60 has on the outer circumferential surface a plurality of projections 90 which project radially outwardly from a plurality of circumferentially spaced positions. Each projection 90 has: a rising surface 92 rising from the minimum diameter position to the maximum diameter position along the circumferential direction of the driven gear 60 in the opposite direction of the rotating direction thereof; and a falling surface 94 falling from a maximum diameter position to the adjacent minimum diameter position in the opposite direction of the rotating direction. The circumferential length L2 of the falling surface 94 is larger than the circumferential length L1 of the rising surface 92. As a result of these conditions, the gap on the outer circumference side of the falling surface 94 is formed to be gradually enlarged toward the downstream side while getting the effect that a relatively large dynamic pressure P is generated in the hydraulic oil on the outer circumference side of the rising surface 92 to enhance the automatic alignment capability of the driven gear 60. Such a formation prevents increase in pressure drag due to peel off of the hydraulic oil in the gap, whereby the rotational resistance of the driven gear 60 is reduced.  <P>COPYRIGHT: (C)2011,JPO&INPIT
