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 (33), and cooperates with a cover member (35) to define a reservoir chamber (37). A cover member (17) also defines a pair of fluid inlet ports (51). A valve actuating member (55) is received in a central bore (53) defined by the input shaft (21). The coupling device includes a valving arrangement (57) including a U-shaped fulcrum element (59) and a flat, elongated valve element (61). The valve (61) passes through slots (69) in fulcrum portions (65) of the fulcrum element. The valve (61) includes terminal portion (67), such that forward movement of the actuation member (55) moves a central portion of the valve (61) forwardly, while moving the terminal portions (67) rearwardly to block fluid flow through the inlet ports (51).
