  • Load bearing solenoid operated valve and method of making same
    Patent number: 6588726
    Abstract: A load bearing solenoid operated valve having a one piece body with threads on opposite ends thereof for connection to a system placing the valve in tension or compression. An inlet port is formed in one end of the body and a plurality of cross ports are formed to communicate with the inlet. A sleeve valve/armature member which is magnetizable is slidably received over the body and has radial ports which are moved axially for valving the body cross ports. An annular flux collector ring and a pole piece are disposed on the body on opposite axial sides of the sleeve valve. A bobbin with coil thereon is received over the body and sleeve and a magnetically permeable cover over the coil completes the flux loop about the coil.
