Abstract
A solenoid valve (10) comprises a body (12) received within a stepped opening (13) of a modulator body (11). The solenoid valve (10) includes a first opening (16) communicating with a chamber (40) and second (20) and third (22) openings communicating with an interior area (30) of the solenoid body (12). Located within the chamber (40) is a shuttle valve (50) having a longitudinal through-opening (52) with an orifice opening (54) and a transverse opening (56) communicating with the chamber (40) and intersecting the longitudinal through-opening (52). An armature (100) is disposed within the interior area (30) and has a first valve member (101) which may seat sealingly with a valve seat (53) of the longitudinal through-opening (52) of the shuttle valve (50), and a second valve member (102) which may seat sealingly with a valve seat (28) of the third opening (22). The armature (100) has a pair of parallel axial through-passages (105). The armature (100) and shuttle valve (50) are biased by a spring (51) and each move reciprocably within the solenoid body (12). The second opening (20) extends transversely through the solenoid valve body (12) and intersects orthogonally a pair of openings (21) which communicate with the interior area (30) and are coaxially aligned with the pair of axial through-passages (105) in the armature (100).
