ABSTRACT:
A hydraulic braking system for a towed vehicle provides actuation of the hydraulic pump motor of the towed vehicle responsive to an electrical switch which is closed upon application of the brake pedal of the towing vehicle. However, even after actuation of the hydraulic pump, the towed vehicle brakes are only able to be applied in response to sensed relative movement of the towing and towed vehicle toward each other. A break-away switch sets the trailer brakes in the event of accidental separation of the towed vehicle from the towing vehicle. The control valve may be used in other situations to control a hydraulic pump and associated hydraulic braking system.
