Abstract
A solenoid operated distribution valve for supplying a servomotor in a trailer with a sway control braking signal in response to a sway signal being evaluated in a comparator. A wave spring surrounds the plunger of the solenoid to nullify the movement thereof such that the output force which operates the distribution valve is a direct function of the sway signal.
