Abstract:
In a master cylinder (20), a cap (30) for guiding a primary piston (50) is located within an end opening (24) of a body (22) of the master cylinder (20). The end cap (30) retains a sleeve (40) and other components within a bore (12) of the master cylinder (20), and is attached to the body (22) of the master cylinder (20) by way of a biasing retention mechanism (45; 145, 150; 260). The mechanism (45; 145; 150; 260) may bias the end cap (30) axially inwardly of the bore (12), bias a gripping ring member (145) radially outwardly into engagement with the body (22) of the master cylinder (20), and retain a first end (32) of the end cap (30) within the bore (12) in accordance with the extent to which the first end (32) is inserted axially into the bore (12).

Abstract:
A method of manufacturing a tandem brake booster by selectively choosing a front shell having a first cylindrical body with first effective diameter, a transition shell having a second cylindrical body with a second effective diameter and a rear shell having a third cylindrical body with a third effective diameter. The cylindrical body of the transition shell is an integral component of an end wall which separates the interior of the resulting tandem brake booster. The end wall has a peripheral edge with a flange extending therefrom and a groove located on the flange connected to the second cylindrical body. An annular surface on the first cylindrical body is crimped into the groove on the flange while a corresponding annular surface on the second cylindrical body is crimped onto the third cylindrical to join the transition shell with the rear shell to form an integral unit.
Abstract:
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).
Abstract:
The combination solenoid valve and shuttle valve (60) with self-cleaning orifice (92) comprises a shuttle valve (50) which is slidingly and sealingly received at an end (40D) of the solenoid valve (40). The shuttle valve (50) includes a stepped interior opening (54) which includes an insert (55) providing a shuttle valve seat (91) opposite a self-aligning solenoid valve seat assembly (94) of the solenoid valve (40). The valve seat (91) of the shuttle valve (50) includes an orifice (92) which extends from an end opening (70) of the insert and communicates with an insert passage (63) at an outer radial portion of the insert (55). An opposite radial side of the insert (55) includes a port (67) which communicates with a longitudinal passage (66) of the insert (55). Disposed within the longitudinal passage (66) is a brake-master cylinder check valve (59), and a stabilization check valve (58) adjacent a filter element (80) which permits communication with the insert passage (63). The shuttle valve (50) includes an end passage (64) having a pump check valve (57) and which communicates with an interior cavity (65) of the insert member (55). Fluid pressure from a pump mechanism (18) causes the shuttle valve (50) to be displaced and engage the shuttle valve seat (91) with the self-aligning valve seat assembly (94) so that fluid pressure from the pump mechanism (18) passes around the pump check valve (57), through the filter element (80) and insert passage (63), and out both ends of the orifice (92) for transmission to a second bore section (72) and a wheel brake (16) and to a first bore section (71) and a pressure producing device such as a master cylinder (12).
Abstract:
An optical particle counter generates a signal indicating an amount of radiation scattered by aerosols in a sample flow. Smoke can be discriminated from other aerosols in the sample flow by analyzing the AC component of the signal. Smoke has a much higher signal-to-noise ratio than do larger particles such as dust and fog.
