AIR BRAKES DESIGN AND PERFORMANCE - Past, Present, Future 480224
A SURVEY of recent developments in the field of air brakes is presented here. For instance, improved versions of the compressor, brake valve, relay emergency valve, and the hose coupling are described.
The rotochamber, which is an improved type of brake chamber is covered, as well as a new, combined quick-release and limiting valve, and also the protection valve, which seals off the straight air and emergency trailer connection on the tractor, should the trailer break away.
The author also emphasizes the importance of maintenance in keeping the brake system operating at top efficiency, for he believes that most of the chronic braking troubles being experienced today on heavy-duty vehicles could be eliminated if the brakes were analyzed and then subjected to a well-planned and executed periodic maintenance program.
