Abstract
A fluid coupling device is disclosed of the type including an input coupling member (11) rotatably disposed within an output coupling assembly (13). A portion of the output coupling assembly comprises a cover member (17) which cooperates with a housing member (15) to define an operating chamber (31). A valve plate (29) separates the operating chamber (31) from a fluid reservoir chamber (33) and defines a fill opening (41) to permit fluid flow from the reservoir chamber into the operating chamber. In a primary embodiment, the cover member (17) defines a radial passage (79) which is disposed to communicate fluid from the reservoir chamber (33) to the operating chamber (31). Such flow through the radial passage (79) may be controlled by a manual control member (65) which may be disposed in either a normal operation position, blocking flow through the passage (79), or may be rotated to a fluid engaged position in which fluid flows through the passage (79) and into the operating chamber ( 31), independent of the temperature condition being sensed by a temperature-responsive bimetal coil (43).
