    摘要： Provided is an internal gear pump requiring fewer machining steps, allowing inexpensive manufacture, and offering high safety from the standpoint of function. The internal gear pump 1 comprises: a trochoid 4 in which an inner rotor 3 having a plurality of outer teeth is eccentrically and rotatably accommodated in an outer rotor 2 having a plurality of inner teeth, the outer teeth meshing with the inner teeth, and in which a suction-side chamber for suctioning liquid and a discharge-side chamber for discharging liquid that has been suctioned into the suction-side chamber are formed in between the inner teeth and outer teeth; a casing 5 in which is formed a recess 5a for accommodating the trochoid 4; and a cover 6 for closing off the recess 5a of the casing 5. At least some of the casing 5 is a body injection-molded from a resin composition. The invention also comprises a groove 5d in a portion of the recess 5a of the casing 5 in which the outer periphery is sealed, with a sealing ring 13 installed therein, and bushings 7 made from sintered metal that are provided integrally during injection molding in bolt fixing hole portions.

    摘要： A fuel pumping unit has a low pressure pump, a high pressure pump, and a drive input which drives the low and high pressure pumps. The low pressure pump supplies, in use, fuel at a boosted pressure to the high pressure pump. The fuel pumping unit further has a low pressure housing containing the low pressure pump, and a high pressure housing containing the high pressure pump. The housings are joined together at a housing interface. The drive input is contained in one of the housings, whereby drive from the drive input is transferred across the interface to the pump in the other housing. The housing interface includes a gap which interposes between the high pressure pump and the low pressure pump. A layer of substantially stagnant fuel is trapped, in use, in the gap to reduce heat transfer from the high pressure pump to the low pressure pump.
