摘要： The pump (10) with integral sump (100) comprises a pump body (12) having therein a bore (18) in which is disposed a resiliently biased and reciprocating pump piston (30). One end of the pump piston (30) is received within an end opening (22) of the bore (18) and a central opening (42) of an outlet member (40). The outlet member (40) includes outlet valve openings (45) each housing a coil spring (41) or elastomeric member (41A) biasing a valve member (43) against a valve seat (49). The valve openings (45) communicate with an interior opening or pumping chamber (44) of the outlet member (40) wherein a spring member (46) biases an inlet valve (60) against an inlet seat plate (70). The inlet seat plate (70) has a central opening (72) communicating on one side with a sump chamber (110). A sump sleeve (90) is located sealingly within the bore (18) and abuts the inlet seat plate (70), contains therein a slidable sump piston (98) biased by a sump spring (96), and has a plurality of inlet openings (92). Reciprocating movement of the pump piston (30) draws fluid through the inlet opening (92), sump chamber (110), central opening (72) of the inlet seat plate (70), and past the retracted inlet valve (60) so that after closure of the inlet valve (60) when the pump piston is at dead center, subsequent movement of the pump piston (30) into the bore (18) causes the fluid to be pumped past the valve seats (49) and valve members (43) and through outlet openings (48).

摘要： A housing for a pump having a cavity therein formed by first and second side walls connected to first and second semicircular end walls. A pair of intermeshing gear members are journaled in a floating bearing and a fixed bearing are located in the cavity. The intermeshing gear members respond to a clockwise rotary torque to pressurize fluid in transporting a fluid from an entrance chamber to a discharge chamber. The fluid in the discharge chamber acts on and urges the floating bearing and fixed bearing into engagement with portions of the first and second semicircular end walls and first side wall to seal the entrance chamber from the discharge chamber. The intermeshing gear members respond to a counterclockwise torque by transporting fluid from the discharge chamber to the entrance chamber to develop an internal fluid pressure. The internal fluid pressure acts on and urges the floating and fixed bearings toward the first and second semicircular end walls and second side wall. The housing has an axial slot that extends from a first point in the first semicircular wall, and through the second side wall to a second point in the second semicircular wall such that the floating and fixed bearing do not seal the discharge chamber from the entrance chamber and as a result the development of the internal pressure is limited to a function of the depth of the axial slot.

摘要： The production of complex cavities inside castings or semi solid forms is effected by forming a core pattern (10) of a low melting point metal in order to provide a rigid metal core pattern (10). The pattern (10) is then nickel coated using either electroplating or electroless nickel plating. The metal core pattern (10) is melted out of the nickel plating to provide a nickel liner core (16). The nickel liner core (16) is placed within a mold or die cavity, and molten metal introduced into the cavity in order to provide a casting or form (30). The casting or form (30) is removed from the cavity and includes therein a plurality of passageways (20) each of which is defined and surrounded by a corrosion resistent nickel liner surface (22).

摘要： A shut-off valve sealing system for a removable cartridge-type filter which includes a body having an inlet to conduct fluid to be filtered therethrough to an inlet of the filter cartridge. The body has an outlet to conduct filtered fluid therethrough from an outlet of the filter cartridge when supported on the body, and a central opening in communication with the inlet and the outlet. A seal member is provided on the body about the central opening. A valve member is movably mounted on the body and movable against the seal member to shut off the inlet when the filter cartridge is removed from the body. A retainer member is provided for retaining the seal member on the body, the retainer member projecting beyond the seal member and providing a stop for stopping movement of the valve member.

摘要： A pump having a pair of intermeshing gear members retained in first and second bushings located in a cavity for pressuring a fluid from an entrance pressure to a desired exit pressure. The first bushing has a passage located therein which communicates a selected pressure less than the exit pressure which acts on an outer face of the first bushing to develop a clamping force which urges an inner face on the first bushing into engagement with the intermeshing gear members and the intermeshing gear member into engagement with an inner face on said second bushing to seal the entrance chamber from the exit chamber.

摘要： The pressure-producing device (10) comprises a housing (30) which is slidable relative to a stationary piston (60), the housing (30) movable within a substantially blind bore (12) to effect the pressurization of fluid. A body (14) containing the blind bore (12) includes a retention member (22) located adjacent an end opening (16) of the blind bore (12). The pressure-producing device (10) is received within the blind bore (12) wherein a closed end (32) with a seal (44) thereabout defines with an end of the blind bore (12) a pressurizing chamber (50). The piston (60) is received slidably and sealingly within an interior opening (39) of the housing (30) and extends from an end opening (34) thereof in order to engage the retention member (22) and position stationarily the piston (60). The housing (30) and piston (60) are displaced away from one another by a pressurized medium within the housing (30 ). The piston's (60) stationary position enables the housing (30) to slide within the blind bore (12) and effect the pressurization of fluid received within the chamber (50).

摘要： The low-noise pump assembly (10) comprises a unitized assembly wherein a drive shaft (17) of the motor (16) is mated directly with an eccentric coupling (23). The eccentric coupling (23) has a through bore (21) which receives at one end the drive shaft (17) and at the other end a center post (30) of the pump housing. Disposed between the center post (30) and eccentric coupling (23) is a radially inner bearing mechanism (60), and disposed between the exterior of the eccentric coupling (23) and an opening (52) of a ring member (50) is a radially outer bearing mechanism (70). The ring member (50) engages at least one reciprocating piston assembly (45). Rotation of the drive shaft (17) causes rotation of the eccentric coupling (23) to effect reciprocating motion of the pump piston (48).
