PCT No. PCT/JP88/00230 Sec. 371 Date Oct. 31, 1988 Sec. 102(e) Date Oct. 31, 1988 PCT Filed Mar. 1, 1988 PCT Pub. No. WO88/06692 PCT Pub. Date Sep. 7, 1988.A fluid control solenoid valve comprises a housing defining therein a fluid passage including a valve seat having a valve port for allowing the passage of the fluid. A plunger having a valve body and movable between a valve closed position and a valve open position is slidably guided by a plunger guide with a sliding contact region therebetween. A biasing spring biases the valve toward the closed position, and a solenoid coil is disposed for magnetically driving the plunger to the open position against the spring action. The solenoid valve further comprises a nonmagnetic cover disposed around the plunger for substantially closing the sliding contact region between the plunger and the plunger guide against ingress of any foreign matter entrained in the fluid.
