ABSTRACT:
An anti-jackknifing valve is designed for use with tractor trailers and is operably inserted in the hydraulic fluid brake line of such vehicles. The valve prevents jackknifing of a trailer during brake applications by initially actuating the brakes on the trailer. The valve arrangement directs hydraulic brake fluid to the trailer brakes first, and a continuing movement of the valve piston then permits hydraulic brake fluid to be delivered to the tractor brakes to thus substantially eliminate the risk of jackknifing.
