The air valve includes a supply valve configured to open and close an air supply passage through which the air gas to be supplied to the fuel cell stack from outside flows; a switching valve configured to switch between a state in which the air gas supplied from the outside flows through the air supply passage and a state in which the air gas supplied from the outside flows through a bypass passage that branches from the air supply passage; and a link mechanism connected to the supply valve and the switching valve and configured to actuate the supply valve and the switching valve. The link mechanism includes an arm portion fixed at the supply valve; and a cam plate fixed at the switching valve, wherein the cam plate includes a guide portion with which the arm portion is to contact.

Air valve and fuel cell system using air valve

A throttle body for traction control includes a secondary throttle shaft, a secondary throttle valve rotatable with the secondary throttle shaft to open and close a throttle bore, and a motor adapted to rotate the secondary throttle shaft for opening and closing the secondary throttle valve. The motor for opening and closing the secondary throttle valve has an output shaft coaxially disposed with the secondary throttle shaft. The output shaft and the secondary throttle shaft are connected by means of a coupling. The secondary throttle shaft is offset from the axis of symmetry of the throttle bore. The secondary throttle valve is divided by the secondary throttle shaft and defines a section which is longer in dimension from the secondary throttle shaft to the end of the secondary throttle valve and another section which is shorter. The longer section is disposed downstream in air flow, so that air flowing through the throttle bore exerts on the secondary throttle valve a force acting to open the same.
