The valve holder has a tube body facing to the suction element, and a small tube portion formed smaller in diameter than the tube body, pierced a fluid insertion hole in an intermediate portion, and having a retention portion retaining the valve body in an inner side of a leading end.

Solenoid valve

A solenoid operated valve &prime; comprises a coil a suction element a plunger a spring a valve member a bobbin a housing and a cap wherein the plunger is moved toward the suction element when electricity is supplied to the coil A pipe sleeve is formed as a deep-drawn integrated pipe with a bottom, which is inserted to the inner side of the bobbin and to which the suction element is inserted and fixed. The plunger is slidably inserted to the pipe sleeve The valve member fixed to the end of plunger opens or closes a valve opening A cylindrical filter is fit to the outer peripheral of a flow-in opening and assembled to a corresponding member.
