摘要： A fuel pump assembly for use in an engine, the fuel pump assembly comprising a plurality of pump heads (13a, 13b, 13c) mounted upon a main pump housing (10), wherein each of the pump heads (13a, 13b, 13c) includes a pumping plunger (14) which is reciprocable, in use, within a plunger bore (16) under the influence of an associated drive arrangement (24, 26) so as to cause pressurisation of fuel within a pumping chamber (22) defined within a pump head housing (18a). The drive arrangement of each pump head includes a shoe (24) and a roller (26) which is cooperable with a driven cam (28), common to each of the pump heads (13a, 13b, 13c), so as to impart reciprocal movement to the shoe (24) as the cam (28) is driven, in use. The shoe (24) is of substantially square or rectangular cross section an each pump head further includes an insert (30a) being formed as a separate part from the main pump housing (10) but being in permanent attachment therewith, wherein the insert (30a) defines a guide path of substantially rectangular or square cross section corresponding to that of the shoe (24) so that the guide path serves to guide movement of the shoe (24) upon reciprocal movement thereof.

摘要： The invention relates to a piston pump for a slip regulating device in a hydraulic automobile brake system. For a more economical production, the invention provides a piston (40) of the piston pump to be constructed as a composite piece with a core (42). The core (42), for example, can be made of steel and surrounded by a plastic sliding case (44). The sliding case (44), for instance, can be placed on the core (42) by means of extrusion-coating and can also be pressed or pushed onto the core (42). The sliding case removes the need for costly subsequent machining of the piston surface, for example through grinding, and improves the sliding properties of the piston (40).

摘要： The invention relates to a piston pump (10) especially for a slip regulating device in a hydraulic automobile brake system. The piston pump (10) consists of a piston (16) which moves within a cylinder sleeve (26), said cylinder sleeve being mounted in the cylinder bore (12) of a pump case (14). The pump case contains a closing device (68) which is sealed by means of a pressure seal. According to the invention, component assembly is simplified by connecting the closing device (68) to the cylinder sleeve (26) by means of a snap or notch connection (72, 80). The handling of the pre-assembled components is thus simplified before their installation into the pump case (14).

摘要： A high-pressure fuel supply pump with high performance is capable of securely preventing a cylinder section from seizing up and also permits improved sealing performance to minimize the chance of fuel leakage. The high-pressure fuel supply pump has: a casing (48) having a cylindrical cavity (48a); a sleeve (40) which has a cylinder section (40a) and a fixing section (40c), one end thereof closer to the fixing section (40c) being abutted against the bottom of the cavity (48a); and a piston (53) which is disposed in the cylinder section (40a). The high-pressure fuel supply pump takes in fuel through an intake passage (36) by the reciprocation of the piston (53) into a fuel pressurizing chamber (52) to pressurize it, then discharges the pressurized fuel through a discharge passage (37) to forcibly feed it into a fuel injector of a cylinder injection engine. A cylindrical slit (40d) is provided between the cylinder section (40a) and the fixing section (40c) of the sleeve (40), and the fixing section (40c) is secured by being fastened toward the bottom of a cavity (48a) by a cylindrical fastening member (64) screwed to the cavity (48a).

摘要： The present disclosure relates to a pump (100, 200) for supplying high-pressure fuel to a common rail fuel injection system. The pump (100, 200) comprises an elongated aperture (109, 209) forming a pumping chamber (111, 211) and a pressurisation chamber (119, 219); a pumping element (113, 213) configured to reciprocate within the elongated aperture (109, 209) to pump fuel from the pumping chamber (111, 211); and pressurisation means for pressurising fuel in the pressurisation chamber (119, 219). The pressurisation chamber (119, 219) extends at least partially around the circumference of the pumping element (113, 213) to reduce leakage from the pumping chamber (111, 211).
