Volvo d13 air compressor unloader valve.

What the unloader valve does is that is responds to the compressor pressure switch turning the power off to the motor and allows any air that may be trapped over the piston or pistons on a multi cylinder air compressor to vent to atmosphere removing any load that the trapped air may have. This will effectively emulate the operation of the unloader valve as any air trapped over the piston will flow into the tank as the tank pressure drops. The compressor s unloader mechanism and governor along with a synchro valve for the bendix duraflo 596 air compressor control the brake system air pressure between a preset maximum and minimum pressure level by monitoring the pressure in the service or supply reservoir.

Plug the compressor back in. Most of the time an internal diesel air brake compressor coolant leak is the result of a failed head gasket. As the system reservoir air pressure drops the force exerted by the air pressure on the piston will be reduced and the governor spring will push the piston down. If your electrically powered air compressor is having a hard time starting try pulling the power cord and opening the drain valve to void all air from the tank.

My air compressor is leaking coolant internally externally. Reservoir air flows around the inlet valve through the passage in the piston and out through the unloader port 2 to the compressor unloading mechanism. The air compressor unloader valve vents trapped air. We ship our air compressors within 24 hours of order placement and we export to over 98 different countries.
