Kind Code:
B1
Abstract:
A hydrodynamic brake for vehicles, especially for motor vehicles with at least one fixed blade wheel and one rotating blade wheel rotating with the drive of the vehicle, in which a filling pump for filling the hydrodynamic working circulatory system rotates also constantly with the drive; the filling pump is adapted to be connected by way of a regulating valve either with the oil sump or with the outlet of the hydrodynamic brake and the pressure is thereby automatically controllable corresponding to the pressure in the brake circuit of the vehicle; a closure valve is also associated with the brake which opens up the external circulatory sysem of the hydrodynamic brake only above a predetermined pressure at the inlet or outlet of the hydrodynamic brake and closes the same below the predetermined value.
