ABSTRACT:
A control system for a hydrokinetic brake has a pressurized working fluid reservoir connected to the hydrokinetic brake by fluid feed and return lines. A regulating valve sets the pressure in the reservoir at a value related to a required braking torque. The inlet pressure of the hydrokinetic brake is maintained at a fixed value lower than the reservoir pressure, for example by an atmosphere vent, during normal braking operation so that the outlet pressure of the brake and hence the braking torque has a direct relationship with the reservoir pressure, irrespective of the rotational speed of the brake.
