摘要: A solenoid-operated cutoff valve for use with fuel cells has a movable member disposed in a guide housing for displacement upon energization of a solenoid. When the movable member is displaced, a pilot valve is unseated from a pilot valve seat. A fluid in a communication chamber flows through a pilot passage into an output port. The communication chamber is divided into a first communication chamber and a second communication chamber by a diaphragm. Under a pressure difference developed between the first communication chamber and the second communication chamber, a main valve of a valve head is unseated from a valve seat of a valve housing, opening the solenoid-operated cutoff valve.

摘要: 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.

摘要: A regulator for use with fuel cells, which is mounted in a pressure controller of a fuel cell system, has a first diaphragm flexible under the pressure of pilot air supplied as an oxidizing agent to a pilot chamber, a second diaphragm flexible under the pressure of a hydrogen-containing gas flowing through a fluid passage, and a rod connected to a valve head. The spring force of a first spring is set to a value greater than the spring force of a second spring. The regulator is of a normally closed type in which the valve head is seated on a valve seat when the pilot air is not supplied to the pilot chamber.

摘要: A check valve is disposed in a hydrogen offgas circulation path which is connected to a fuel cell so as to flow the hydrogen offgas only in one direction. Inside a valve housing, a first compression chamber and a second compression chamber are provided such that a bulkhead is disposed therebetween. In the bulkhead 14, a first communication hole 18 and a second communication hole 19 are formed so as to communicate between the first compression chamber and the second compression chamber. In a first reed valve, an opening end is disposed upward and a fixed end is disposed downward. In a second reed valve, an opening end is disposed downward and a fixed end is disposed upward. By doing this, operability in the check valve after water has frozen can be improved.

摘要: A back pressure chamber is defined at an end of a rod for acting in a direction to cancel out a pressure applied to a valve head, and an aspirator chamber is defined closely to the valve head for developing a pressure lower than a secondary pressure due to a suction caused by a nozzle. The rod has a first communication hole and a second communication hole that are defined therein which provides fluid communication between the back pressure chamber and the aspirator chamber.

摘要: In a fuel evaporator provided with an evaporation chamber 11 that produces raw fuel gas FG by vaporizing raw fuel liquid by heat received from a plurality of heat medium tubes 12 through which a high temperature heat medium passes, a raw fuel injection portion that injects raw fuel liquid onto the heat medium tubes 12 is situated in the evaporation chamber 11. The heat medium tubes 12 are arranged sparsely near the raw fuel injection portion and densely away from it. A catalytic combustor 20 is provided adjacent to the bottom surface 11b of the evaporation chamber 11 to form the high temperature heat medium. Such a fuel evaporator efficiently vaporizes raw fuel liquid and can be suitably applied in a fuel cell system for a fuel cell-powered automobile.
