Abstract
A clutch arrangement having an input element and an output element that are rotatable relevant to one another, a friction clutch and a pump. The friction clutch couples the input element with the output element in dependence on a hydraulic pressure in a pressure space of the clutch arrangement. The pump has a first pump part that is rotationally fixedly connected to the input element and a second pump part that is rotationally fixedly connected to the output element. The pump may be driven by a rotary movement of the input element and the output element relative to one another, with a pressure side of the pump being connected to the pressure space. An orifice having a substantially temperature independent leakage characteristic is arranged in a leakage line that leads from the pressure space to a low pressure space and which extends parallel to the pump.
