<p>The combination solenoid valve and integral shuttle shuttle valve (10) comprises a solenoid valve (40) having windings (41) which actuate a rod (43) that engages a ball valve (44). An end (61) of the solenoid valve (63) includes an end filter mount (80) having a filter (77) and engaged by a shuttle valve (50). Located sealingly and slidably within the end (61) of the solenoid valve (41) is the shuttle valve (50) which is biased away from the ball valve (44) by a spring (58). The shuttle valve (50) has at least one through opening (55, 55A) which is aligned with a movable orificed washer (90) located about an extension (54) of the shuttle valve (50). An end section (74) of the bore (17) adjacent the end (61) of the solenoid valve (40) includes a master cylinder passage (14), a first bore section (71) includes a pressure source passage (20) and communicates with lateral openings (49) in the end (61) of the solenoid valve (40), a second bore (72) section communicates with a wheel brake passage (13) and with lateral openings (48) in the solenoid valve (40), and a third bore section (73) communicates with a sump passage (24) that is aligned with lateral openings (47) in the solenoid valve (40). During operation of the solenoid valve (40), the shuttle valve (50) can slide and displace the washer (90) into engagement with a body member (91) of the solenoid valve (40) and cause pressurized fluid from the master cylinder passage (14) and pressure source passage (20) to communicate through an orifice (92) of the washer (90).</p> |
