Abstract
A solenoid operated valve has a valve body with a plurality of ports and a spool slideable within the valve body to interconnect the ports in different combinations. An actuator includes a solenoid coil assembly and an armature slideably received in the solenoid coil assembly. A bushing has a cylindrical body from which a push member projects into engagement with the spool and from which a coupling shaft extends into an aperture in the armature. A passage is provided in the bushing to allow fluid to flow between opposites sides as the bushing slides in the solenoid coil assembly. The cylindrical body rides in the solenoid coil assembly and has a plurality of external grooves that enable fluid to pass around the body.
