THREE-WAY SOLENOID VALVE |
摘要 |
<p>A valve includes a bobbin/valve body, a solenoid and a plunger. The bobbin/valve body is formed in one piece, defines all of the valve's inlet/outlet ports and forms the entire support structure for the solenoid and the plunger. To assemble the valve, a plunger body is inserted into the bobbin/valve body through an end opening into a longitudinal bore and a spring positioned to bias the plunger body to a normally closed position. A pole piece is then inserted through the end opening into the longitudinal bore and attached to the bobbin/valve body. A solenoid coil is wound around a central cylindrical section of the bobbin/valve body, and terminal pins and a flux conductor are attached to the bobbin/valve body. The attachment of the pole piece, the terminal pins, and/or the flux conductor may be accomplished by press-fit and/or swage coupling techniques.</p> |
