摘要： The differential pressure shuttle valve (10) comprises a stepped bore (14) having enlarged (16) and reduced (18) diameter sections. The reduced diameter section (18) communicates with first (20), second (22), and third (24) openings, and the enlarged diameter section (16) is divided into two chambers (50, 60) by an enlarged end (42) of a valve member (40, 140, 240). The valve member (40, 140, 240) includes a central through passage (48, 148, 248) which communicates with the first chamber (50) between the enlarged end (42) of the valve member (40) and the enlarged diameter section (16) of the stepped bore (14). The second chamber (60) is defined between the enlarged end (42) of the valve member (40) and a shoulder (17) disposed between the enlarged (16) and reduced (18) diameter sections of the bore (14). The second chamber (60) communicates with a fourth opening ( 70) and includes therein a resilient member (80) which biases the valve member (40, 140, 240) away from the first opening (20). A pressure differential across the valve member (40, 140, 240) causes the valve member (40, 140, 240) to shuttle and compress the resilient member (80) so that a reduced end (44, 144, 244) of the valve member (40, 140, 240) engages an end of the bore (14) or insert (28, 90, 228) such that the first opening (20) is isolated from the second (22) and third (24) openings.

摘要： The combination solenoid valve and shuttle valve (60, 160A-D, 260A-D) comprises a shuttle valve (50, 150) which is slidingly and sealingly received at or adjacent an end of the solenoid valve (40, 140). The shuttle valve (50, 150) includes a stepped interior opening (54, 154) which sealingly receives the end of the solenoid valve (40) or a valve part (140A), such that slidable movement of the shuttle valve (50) causes an insert (55, 55A, 155) within the interior opening (54, 154) to seat sealingly over either a solenoid insert seat (41C) or insert seat (141C) of the valve part (140A) in order to isolate pressure chambers (12A, 12B; 112A, 112B; 212A, 212B) of a master cylinder/hydraulic booster (12, 112, 212A, 212B) from a wheel brake (16, 116A-D, 216A-D). The shuttle valve (50, 150) may include a one way build orifice (30, 30 A, 130) which permits restricted fluid flow between a pressure source (18, 101, 201) and the wheel brake (16, 116A-D, 216A-D), a feedback orifice (36, 36A) which permits restricted fluid flow from the pressure source (18) to the master cylinder (12), a pump check valve (23, 123) which prevents fluid flow from the shuttle valve (50, 150) back toward the pressure source (18, 101, 201) and a poppet check valve or floating feedback washer (38, 38A) which when displaced permits fluid flow from the master cylinder (12) toward the wheel brake (16).
