ABSTRACT:
A solenoid valve comprising a housing including a first transverse wall, a first axial extension extending from the transverse wall, and an integral peripheral wall extending axially in the opposite direction from the periphery of the transverse wall. A center pole member includes a pole extending axially within the peripheral wall of the housing and includes a second transverse wall extending radially outwardly into engagement with the peripheral wall. The center pole includes an axial extension extending in the opposite direction from the first axial extension. A coil surrounds the pole piece. The axial extensions of the housing include axial openings and the center pole includes an axial opening aligned with the openings of the axial extensions. A ball valve has limited axial movement between the seats on the center pole and second axial extension. A groove is formed at the area of juncture of the center pole and the second transverse wall and a plurality of axially extending passages extend from the groove to the periphery of the second axial extension.
