Abstract
Abstract An air valve comprising a first valve member mounted for generally universal movement and having a passage therethrough, a second valve member having a passage therethrough and mounted in the passage of the first valve member for pivotal movement relative to the first valve member. Portions of the two valve members are spaced to define a substantially enclosed region within the air valve. An actuator is mounted on one of the valve members within the enclosed region and a switch is mounted on the other of the valve members within the enclosed region. Air is supplied to the passage of the second valve member by a fan which is driven by a motor. By turning of the second valve member, the switch can be opened and closed to thereby control the operation of the motor and of the fan. Air flow through the second valve member can be modulated by an appropriate valve element.
