摘要： The pressure accumulator (10) comprises a cylindrical housing (12) having a bore (14) with a piston received slidably therein. The piston (30) has an H-shaped cross section and includes a reduced diameter portion (34) extending longitudinally along the piston (30), and a sealing device (36, 38) disposed at each end of the reduced diameter portion (34). A cylindrical sleeve (44) is received in the reduced diameter portion (34) such that each end of the sleeve (44) abuts a respective sealing device (36, 38). The housing (12) has an exterior circumferential groove (20) with an O-ring (26) therein, and a radial opening (22) extending between the circumferential groove (20) and bore (14). Alternatively, the piston (30) may have a longitudinal opening (61) extending from one side of the piston to grooves (63, 64) at the other end (32), the grooves (63, 64) receiving a ring (72) which is subjected to fluid pressure transmitted through the longitudinal opening (61) and expanded radially outwardly against an angled portion (73) of a force-transmitting member (74) which moves longitudinally against seals (76, 77) disposed in one of the grooves (63, 64).

摘要： A brake booster (10, 210, 310) connected to a control circuit (120) provides for continued braking of a vehicle when the vehicle is situated on an incline and the brake pedal (92) is released by the operator. Continued brake application is accomplished by utilizing a control circuit (120) responsive to vehicular attitude, clutch pedal position, ignition status, vehicular speed, and vehicular direction. The control circuit (120) is connected to a combination check valve and three-way solenoid valve (100, 200, 300) connected to a movable wall brake booster (10, 210, 310). The combination valve (100) is connected to a flexible hose (110) disposed interiorily of the booster (10), the other end of the flexible hose (110) connected to the input opening (32) of a three-way poppet valve (70) located at the central hub (30) of the booster (10). When the control circuit (120) senses that the vehicle is on an incline, the clutch pedal depressed, the ignition "on", the speed is zero, and the vehicle not backing up, it actuates the three-way solenoid of valve (100) which continues to supply a first fluid pressure to the front booster chamber (40) while supplying a second fluid pressure for the rear booster chamber (50) via the flexible hose (110) and poppet valve 170. The vehicle operator may release the brake pedal (92) which returns slightly toward an inactive position and which opens slightly valve (70), with the brakes remaining activated because the second fluid pressure is provided to the rear chamber (50) via the hose connection (110) and valve (70) to maintain the axially displaced position of the movable wall (24).

摘要： A cover for a retention chamber in a master cylinder reservoir which will permit a probe to pass through a tab and pressurize a piston in a pressurizing chamber with a test fluid under pressure. This test fluid will allow an operator to visually inspect the master cylinder for fluid failures at various pressures. In the normal operation, the tab of the cover will allow fluid to flow from a supply chamber into the retention chamber. However, during a brake application when fluid is transmitted through the compensator port as the pressurizing piston moves past the compensator port, the tab will prevent this fluid from being squirted into the supply reservoir. This will assure that a minimum quantity of fluid is always present in the retention chamber to operate the brake system even though a low fluid level indicator in the supply chamber presents a failure warning signal to the operator.

摘要： The hydraulic brake booster (12) includes a resilient member (96) disposed between an input member (94, 194, 294) and a pair of valve members (98, 101; 112) which control fluid pressure flow from an accumulator (14). When the input member (94, 194, 294) is actuated by the vehicle operator, theresilient member (96) is compressed so that the input member (94, 194, 294) moves relative to the valve members (98, 101; 112) and thus provides for greater movement of the input member (94, 194, 294) than for the valve members (98, 101; 112). The booster (12) includes a hydraulic or mechanical lockout which, in the absence of fluid pressure from the accumulator (14), eliminates the movement of the input member (94, 194, 294) relative to the valve members (98, 101; 112) so that the relative movement eliminated is not added to the valve stroke during manual operation of the booster (12).

摘要： The accumulator comprises a housing (12, 212) having a bore (16, 216) extending longitudinally within the housing (12, 212), a piston (26, 226) disposed slidably within the bore (16, 216) and dividing the bore (16, 216) into first (18, 218) and second (20, 220) chambers. The piston (26, 226) has a bore (30, 230) with a bore opening (36, 236) at the first piston end (27, 227), the bore opening (36, 236) being enclosed by a sleeve member (70, 271). The sleeve member (70, 271) extends longitudinally away from the piston bore (30, 230) and into the first chamber (18, 218), the sleeve member (70, 271) having a sleeve opening (78, 273) permitting high pressure fluid contained within the first chamber (18, 218) to communicate freely with the piston bore (30, 230). A lubricating fluid (60, 260) is disposed about the first piston end (27, 227) and is prevented from entering into the piston bore (30, 230) by means of the sleeve member (70, 271). The sleeve member (271) may be biased away from the piston (226) by means of a spring (288) disposed within the piston bore (230).

摘要： A push rod assembly having a first section and a second section through which an input force is transmitted to an output member. The first section includes a cylindrical member with a bellows attached thereto. The cylindrical member has a bore therein. The second section includes a piston that is attached to a brake pedal by a pivot pin. The piston divides the bore in the cylindrical member into a first chamber and a second chamber. The piston has a passage therethrough that connects the first chamber with the second chamber. A valve located in the passage controls the communication of fluid from the first chamber to the second chamber. A linkage member which extends into the bore in the cylindrical member is connected to a plate with a slot therein. The pivot pin associated with the brake pedal extends through the slot to attach the plate to the brake pedal. In the rest position, the plate engages a stop and allows the pivot pin to move in the slot and bring the linkage member into engagement with the valve to allow free communication through the passage in the piston. A switch member, responsive to movement of the brake pedal by an input force, allows a source of vacuum to evacuate air from the bellows to create a pressure differential therein with air in the surrounding environment. The pressure differential causes the bellows to contract and thereby move the cylindrical member at a faster rate than the piston and move the valve away from the linkage to interrupt the fluid communication through the passage. With fluid communication through the passage interrupted, a fluid lock is created in the first chamber. Thereafter, the input force from the brake pedal is transmitted to the cylindrical member from the piston through the fluid in the first chamber.

摘要： The shuttle valve (10) has a valve member (30) which includes first (32) and second (36) diameter sections disposed within small diameter (22), reduced diameter (24), and enlarged diameter (26) bore sections of a stepped bore (14) located in a valve body (12). The small diameter bore section (22) communicates with a brake feedback line connection (20), the reduced diameter bore section (24) communicates with an outlet opening (40), and the enlarged diameter bore section (26) communicates with an inlet opening (50). The second diameter section (36) of the valve member (30) includes a transverse opening (44) which communicates with a longitudinal orifice opening (46) that leads to a chamber (48) located at an end of the valve member (30). Seals (60, 70) are disposed about the first and second diameter sections (32, 36), and the valve member (30) biased by a spring (80) toward an at-rest position. Located about the first diameter section (32) of the valve member (30) is a freely movable orifice member (90) which includes a radial orifice opening (94) at one surface thereof. The sudden communication of high fluid pressure through the inlet opening (50) results in a slightly delayed displacement of the valve member (30) and movable orifice member (90), and the displacement of the valve member (30) and movable orifice member (90) then causing fluid to be communicated through the movable orifice opening (94) so that fluid communication with the outlet opening (40) is restricted.
