Abstract
A fluid clutch composed of a primary part with a drive disc and rotatably mounted relative to a secondary part with a cover is constructed so that the drive disc is disposed in a working chamber formed in the secondary part, the working chamber communicating through a return channel with a supply chamber formed in the secondary part for returning the clutch fluid from the working chamber to the supply chamber by action of a retarder provided in a gap between the circumference of the drive disc and a radial boundary of the working chamber. A control element disposed in a control chamber is displaced axially relative to the drive disc and is located in the secondary part. In accordance with a preferred embodiment, two bores are provided at an angle extending radially and circumferentially relative to the drive disc and control chamber, which bores terminate in the vicinity of the circumferential ends of the retarder in the gap between the drive disc and radial boundary of the working chamber, as well as in the control chamber. Movement of the control element within the control chamber exposes a return channel extending from the control chamber to the supply chamber and alternately exposes and blocks a respective one of the two bores, depending upon the direction of rotation of the drive disc.
