ABSTRACT:
A vehicle wheel speed retarding system comprising a positive displacement fluid pump in a liquid system adapted to be driven by positive engagement with means on the wheel drive. The output of the pump is delivered to a valve and governor means also driven by the vehicle wheel drive operates the valve to reduce its flow capacity with increase in speed, thus retarding the positive displacement pump and, hence, the vehicle wheel. Manually regulated means, such as controlled air pressure acting against a diaphragm, resists movement of the valve to control the speed capacity of the device. Failure of air pressure will result in minimum speed capacity.
