A fluid friction clutch (1) including a housing (2, 3), a clutch plate (4) which is situated on an end (5) of a shaft (6) mounted centrally within the housing (2, 3), a working chamber (9) between the housing (2, 3) and the clutch plate (4), a supply chamber (10) for clutch fluid, and a supply channel (11A, 11B) which leads from the supply chamber (10) to the working chamber (9). A feed pump element (14) which is rotatable with respect to the housing (2, 3), is situated rotationally fixed on the shaft (6), and defines a shear gap (12) with the housing (2, 3). A valve (17) is situated between the feed pump element (14) and the supply chamber (10), the valve (17) in the closed position effectively establishing a main working path (HA) between the feed pump element (14) and the working chamber (9), and the valve (17) in an open position unblocking a discharge path (EP) between the feed pump element (14) and the supply chamber (10). |
