Abstract

The pump has a pump shaft (3) driven and stored in a pump storage (1) in a storage housing (2). An impeller (5) freely rotates at a sliding support of the shaft. An eccentric tappet (11) is fixedly arranged on the shaft. A pressure plate (13) is arranged on one or both sides of the tappet in an axially adjustable manner. A bimetal disk (22) that is fixedly arranged in the impeller is fastened adjacent to the turned away side of the plate and at the tappet.
