ABSTRACT:
A hydraulic coupling which includes a primary coupling part having a pot-shaped pulley or sheave, and a secondary coupling part including a housing provided with a cover. The primary and secondary parts are supported relative to one another in such a manner that they can rotate and the pot-shaped pulley or sheave is located in a working compartment formed in the housing. The working compartment is connected by way of a recycling arrangement, including a bore in the cover, to a supply channel to enable a recycling of the coupling fluid. A circumferential surface of the pulley or sheave is provided with spiral or thread-like grooves. At least one baffle or dam body is provided in order to pump off the coupling fluid from the working compartment. The housing is provided, in an interior thereof, with a circumferentially extending channel having an axial length or width when extends over a portion of a depth or axial length of the pulley or sheave. The channel terminates in an end wall, nearest the cover, in a radial plane in which a forward edge of the pulley or sheave is disposed. The dam or baffle body is located in a recess in the housing in such a manner that a radially inner surface of the body is disposed along a cylindrical inner surface of the housing and extends in an axial direction from an area above the supply chamber to a point above the circumferentially extending channel.
