摘要： Example fluid circuits (e.g., within aircrafts) include first and second pump assemblies. The first pump assembly has an electric motor and a first fluid pump. The first fluid pump is coupled to the electric motor and has a case drain port that is in fluid communication with a case drain region of the first fluid pump. The second pump assembly is powered by hydraulic pressure from the first fluid outlet of the first fluid pump and functions to augment flow through the case drain region of the first fluid pump.

摘要： A pump head (14) for a high-pressure fuel pump is disclosed. The pump head comprises a head housing including a body portion (24), and a turret portion (30) extending from the body portion (24), a pumping chamber (36) defined within the body portion (24), a pumping element bore (34) for receiving a pumping element (32) in use, the pumping element bore (34) extending from the pumping chamber (36) and through the turret portion (30), and a leakage return passage (74). The pump head (14) further comprises a sleeve (70) arranged around the turret portion (70) to define a leakage flow path (72) to allow fuel flow from the pumping element bore (34) to the leakage return passage (74). The pump head is suitable for use in a fuel pump of the type in which a cam drive arrangement of the pump is lubricated by engine oil, since contamination of the engine oil with fuel can be minimised.

摘要： A pumping head (200;300) for a high-pressure fuel pump is disclosed. The pumping head comprises a head housing (204) having a bore (206), a pumping element (202) arranged for reciprocal linear movement along a pumping axis (Q), a first pumping chamber (240) and a second pumping chamber (242), inlet means (290;314) for delivering fluid to the first pumping chamber (240), outlet means (246,248) for conveying fluid from the second pumping chamber (242) to an outlet (244) of the pumping head, and transfer means (260,262) for conveying fluid from the first pumping chamber (240) to the second pumping chamber (242). Each forward stroke of the pumping element (202) increases a volume of the first pumping chamber (240) and decreases a volume of the second pumping chamber (242), thereby to cause fluid to flow into the first pumping chamber (240) from the inlet means (290;314) and to cause fluid to flow out of the second pumping chamber (242) to the outlet means (246,248). Each return stroke of the pumping element (202) decreases the volume of the first pumping chamber (240) and increases the volume of the second pumping chamber (242), thereby to cause fluid to flow from the first chamber (240) to the second chamber (242) through the transfer means (260,262).

摘要： The invention relates to a piston pump for a hydraulic pressure generator in a vehicle braking system. The piston pump comprises a housing in which a bore 30 is formed for receiving an eccentric shaft 32. At least six cylinders 12, 14, 16, 22, 24, 26 are further provided for accommodating one pump piston 1, 2, 3, 4, 5, 6 each. The cylinders 12, 14, 16, 22, 24, 26 are disposed in pairs in three or more offset planes (A-A, B-B, C-C) and each open onto the receiving bore for the eccentric shaft. According to one potential embodiment, each braking circuit in a two-circuit vehicle braking system is associated with at least three cylinders to increase operating ease. Each of the provided eccentric shafts works with only two pump pistons in order to reduce wear.
