Abstract

The invention relates to a rotation speed dependent hydraulic clutch consisting of a rotation drive case in a solid case forming a reservoir, a hydrostatic displacement device (1), an output shaft, a friction clutch and a piston (5) for feeding it. In order to attain a rapid characteristic adjustment and matching, a first and a second aperture (9, 10) are connected to a reservoir (8) by means of a first and a second turning introduction element (13, 14) and a control valve (25) fixed to the case. In order to attain a sensitive and rapid characteristic adjustment and matching with minimum complexity. A first non-return valve (18, 19) is mounted on a first (16) and second (17) pipe respectively. A third pipe (23) having a valve control unit (25, 35) is provided from the first pipe (16) and the second pipe (17) respectively through a second non-return valve (22). The first non-return valve (18, 19) and the second non-return valve are oppositely polarised.
