Abstract:
1. A valve for a fuel cell comprising: a housing; a first pressure chamber and a second pressure chamber provided in the housing; two supply/discharge tubes connected to the housing, and supplying and discharging fluid to and from the first pressure chamber and the second pressure chamber, respectively; a drive shaft supported by the housing, and movable in its axial direction when subjected to a force corresponding to a pressure difference between the first pressure chamber and the second pressure chamber; a valve member body fixed to the drive shaft; and a flow path forming pressure chamber extending from an inlet portion to an outlet portion opened on the housing, wherein the flow path forming pressure chamber is disconnected or connected between the inlet portion and the outlet portion of the flow path forming pressure chamber in response to a displacement of the valve member body according to a movement of the drive shaft in its axial direction, and wherein a pressure chamber side opened end of at least one supply/discharge tube of the two supply/discharge tubes is obliquely cut with respect to an axial direction of the one supply/discharge tube such that an area of the opened end is wider than a cross-sectional area of a flow path of the one supply/discharge tube.
