An explanation of how anti-compounding relay valve works in the truck air brake system. Created by the School of Motive Power Technology at Fanshawe College,. An inversion valve with anti-compounding protection Under normal conditions, the IR-2 responds to a control signal from dash-mounted parking brake control valve to supply or exhaust air from the spring brake chambers, thereby applying the spring brakes. In the event of a primary air system failure, the IR-2 makes

When the anti-compounding feature is used, removal of the exhaust cover exposes a 1/8" pipe thread balance port. All ports on the valve are identified. GENERAL OPERATION The rapid reaction of the R-8TM valve to changes in control pressures is in part due to the relatively small volume of air required between the valve cover and the relay piston. Yet, this problem is now obsolete, as the majority of trucks are equipped with an anti-compounding valve. This valve prevents the service brakes from being applied if the parking parking brakes are engaged. 1. 4324070180. Relay Valve, Anti-Compounding with a material number 9730110490 is available.

COMPRESSOR PUMPS BEYOND "CUT-OUT" Check gauge. Check governor. Be certain it pressurizes unloader port when above "cut-out". Check unloader/plungers. Lube, kit or change head. WON'T PUMP AIR Check gauge. Check compressor drive. Check inlet valves and plungers. If stuck, leak will be evident at intake when unloaded. DESCRIPTION The Bendix® QR-1CTM is a dual function valve. The valve's primary function is to serve the emergency side of a spring brake actuator as a quick release valve. In addition, it functions as an anti-compound device. The double check valve prevents a service and emergency brake application from occurring simultaneously.
An engine-driven compressor provides the air, which is constantly being replaced and never needs to be changed. Also, pedal effort is minimal, because it simply involves depressing a treadle valve that sends air to the brake relay valves. The air does need to be kept clean and dry, but the air dryer handles that. Anti-Compounding valve is a relay valve with a double-check valve built into it To see how anti-compounding works, let's use the example where a truck is stopped on a hill, and while the driver holds the foot brake, the driver also sets the parking brakes. Setting the parking brakes would normally release the air from the spring brake chambers which would allow the powerful spring inside the.
