ABSTRACT:
A fluid coupling device is provided of the type including an input coupling member (11) and an output coupling assembly (13). The unit includes a fluid operating chamber (33) and a fluid reservoir chamber (37), and a valve means (55) is included to control the flow of fluid between the chambers. The valve means (55) includes an elongated valve element (57) which is moved axially in response to energization of an electromagnetic coil (75). The valve element (57) includes a control portion (71) which is oriented at approximately a right angle relative to the valve element (57). The flow control portion is in engagement with a cylindrical surface (51) which defines the valve port (53), such that axial movement of the valve element results in sliding engagement between the control portion (71) and surface (51) to cover and uncover the valve port (53).
