ABSTRACT:
A solenoid valve has a housing in which is disposed a coil, a sleeve valve and a plurality of hydraulic fluid passages. The passages are formed in a cylindrical core which is integral with and extends axially from an end wall of the housing. The sleeve valve is slidably mounted on the core and has a pair of annular recesses which are selectively positionable by valve movement to interconnect various combinations of passages for controlling hydraulic fluid flow. The sleeve valve has a metal ring secured thereto so that the sleeve valve will be moved in response to electric current flowing in the coil which surrounds a portion of the sleeve valve.
