Abstract
A fluid coupling device is disclosed of the type including a coupling assembly (13) including a housing member (15) and a cover member (17), the members (15) and (17) including flange portions (61) and (63). The flange portion (63) defines an annular fluid cooling recess (65). Fluid is directed from the operating chamber (33) by means of a fluid-directing member (69) through an inlet opening (67) into the recess (65). Fluid flows circumferentially around the coupling device through the recess (65), with heat being transmitted from the fluid to the flange portion (63) and then dissipated. At the end of the recess (65), the fluid engages an end wall (75) which directs the fluid into an outlet passage (77) and back into the operating chamber. The fluid cooling recess has no direct communication with the fluid reservoir chamber (37).
