Abstract
A valve and method of making same with a valve body defining an inlet and outlet and which communicate with a valving chamber. A cup-shaped glide member in the chamber is sealed over the outlet and has cross-ports over which slide a valving sleeve attached to a ferromagnetic armature. The armature slides in a guide tube which is sealed on the body and closes the valving chamber. The guide tube preferably has a magnetic pole piece attached the end remote from the body. The valving sleeve is attached to the armature in a manner which allows frictional slippage in the direction transverse to the armature motion to permit the sleeve to be guided by the glide member and the armature to be guided by the guide tube. A solenoid coil is received over the guide tube and preferably retained by engagement with the pole piece.
