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 translation: 在主缸（20）中，用于引导主活塞（50）的盖（30）位于主缸（20）的主体（22）的端部开口（24）内。 端盖（30）将套筒（40）和其它部件保持在主缸（20）的孔（12）内，并且通过偏置件附接到主缸（20）的主体（22） 保持机构（45; 145,150; 260）。 所述机构（45; 145; 150; 260）可以轴向地向所述孔（12）的内侧偏压所述端盖（30），从而径向向外偏压夹紧环构件（145），以与所述主缸（12）的主体（22）接合 （20），并且根据所述第一端（32）轴向插入所述孔（12）的程度，将所述端盖（30）的第一端（32）保持在所述孔（12）内。

Abstract: A control valve (10) comprises a valve assembly (12) having a stepped bore (18) which communicates with a first inlet (30) from a master cylinder, a second inlet (40) from a pump, a first outlet (50) to a wheel brake, and a decay outlet (60) permitting fluid flow away from the first outlet (50) during decay of fluid pressure for anti-lock operation. A first valve element (31) comprises a reduced diameter section (34) extending into an enlarged diameter section (32) which is received within a correspondingly shaped enlarged diameter section (22) of the bore (18). The first valve element (31) includes a longitudinal through passage (35) with a restriction (43) therein, and a transverse fluid passage (37) which intersects the longitudinal through passage (35) and communicates with the enlarged diameter section (22) of the stepped bore (18). One end of the first valve element (31) comprises a valve seat (36) disposed adjacent a second valve element (70) that is operated by an actuator (14). A spring (80) extends between the first valve element (31) and second valve element (70) to bias the second valve element (70) towards a closed position at a valve seat (62) of the decay outlet (60). The first inlet (30) communicates fluid pressure from the master cylinder to the enlarged diameter section (22) of the bore (18) to effect fluid communication with the longitudinal through passage (35) separate from fluid pressure received from the pump and communicated through the second inlet (40) to a separate receiving chamber (44) defined between the enlarged diameter sections (22, 32) of the first valve element (31) and stepped bore (18).
