摘要： A pump includes a pump casing and an impeller. The pump casing has an axis and comprises a cover having a face surface and a body positioned about the axis. A channel is defined in the face surface of the cover. An inlet opening extends through the cover and is coupled to the channel. The channel has a first section and a second section. The first section extends from the inlet opening and is continually sloped relative to the face surface of the cover. The first section has a length of about 40 to about 90 degrees, as measured circumferentially on the face surface of the cover about the axis. The first section includes an inlet ramp, a main ramp, and a secondary ramp, with the secondary ramp being positioned between the main ramp and the inlet ramp, and the inlet ramp being positioned adjacent the inlet opening. Each ramp has at least one depth and at least one slope.

摘要： A fuel pump for pumping fuel from an inlet port to an outlet port. In one embodiment, a housing made up of a body piece and a cover piece encloses an impeller. The impeller has a vaned periphery and an outer ring connected by spokes. An inlet hole is defined within the cover piece for fuel to enter the pump. An outlet hole is defined within the body piece for fuel to exit the pump into an internal chamber. A first main semicircular shaped channel is defined circumferentially into the cover piece and extends in an annular fashion around the cover piece. The body piece has a second main semicircular channel as well as at least one annular groove. In the preferred embodiment of the invention, there are two annular grooves, one connected directly to the second semicircular channel, and one around the peripheral edge of the body piece at the point where it contacts the cover piece.

摘要： Vane pieces (31) which are in an outer peripheral edge portion of an impeller (30) are divided into front and rear groups by a partition wall (32), and arranged in a staggered pattern, and outer peripheral faces of the vane pieces (31) are protruded toward the outer peripheral side with respect to the outer peripheral face of the partition wall (32). Therefore, fuel portions respectively entering vane grooves (33) which are divided into front and rear groups do not simultaneously collide against end faces (9b) of radial seal portions (9a). Consequently, the level of noises due to the fuel collision can be lowered. Furthermore, a reverse-flow region is prevented from being produced immediately above the partition wall (32). Therefore, the pump efficiency can be improved.
