A diaphragm is clamped between a solenoid unit disposed in a casing and a second valve body in which hydrogen is introduced. A filter comprising a bottomed cylindrical mesh member is mounted in a first passage defined in the first valve body. A restriction having an orifice for restricting the flow rate of hydrogen supplied to first and second communication chambers is mounted in a first port that is disposed upstream of the filter. The restriction and the filter are disposed coaxially in line with each other.

Solenoid valve for fuel cell

A solenoid-operated valve for use with fuel cells has a valve housing made of aluminum, for example and having first through third heating medium passages defined therein. A valve seat disposed in and fastened to the valve housing is made of stainless steel, for example. A valve head has a disk which can be seated on and unseated off a valve seat member of a valve seat. The valve head is coupled by threaded surfaces to the distal end of a movable member which is displaceable when a solenoid is energized. The movable member is made of a magnetic metallic material, and the valve head is made of a corrosion-resistant metallic material such as stainless steel or the like, for example.

Solenoid-operated valve for use with fuel cells

A valve housing has a bottomed hollow cylindrical main body and a boss projecting from and smaller in diameter than the main body. The main body has a tapered surface circumferentially along a joint where a side wall and a bottom wall of the main body are joined to each other. A plurality of inlet ports are defined in the tapered surface. The boss has an outlet port for discharging a fluid introduced into the main body. When a valve head coupled to the movable member is displaced and a seating ridge of a resilient member mounted on the valve head is seated on a valve seat surface, the inlet ports and the outlet port are brought out of fluid communication with each other.
