Abstract

A fluid control system for use with vehicles, in particular, trailers, includes a branch conduit which is to be connected to a pressure supply line and a control line to enable priming of the control line so that signals generated upon application of the vehicle brake pedal are more quickly transmitted to the trailer brakes. This overcomes problems associated with delay in application of the trailer brakes. An electrically operated solenoid valve controls fluid flow through the branch conduit so that upon application of the vehicle brake pedal the solenoid valve is operated to open the branch conduit to allow pressurized fluid to flow from the supply line to the control line for a predetermined time period to prime the control line. Pressurized fluid from the branch supply conduit is directed longitudinally down the control line by a longitudinally arranged outlet so that substantially all of the fluid is directed to backfill the control line. The system may be embodied in a block arrangement in which bores are drilled in a block housing and in which the branch conduit is formed by passages drilled in the block or may be formed from discrete hose sections and couplings.
