TC throttle controls are used on gas engine-driven compressors to reduce engine speed to idle when the continuous run control (such as CDI model LGM20 and LGM30 vent unloaders or model P25 pilot valve) has reached its “cut out” setting.
This saves fuel and reduces engine and compressor wear.
The 1/8”NPT inlet of the TC is connected to the throttle control part of the vent unloader or connected into a “tee” of the head unloader line of pilot valve installations. The cable end is attached to the appropriate throttle linkage on the engine and the cable housing is appropriately anchored using the supplied cable clamps.
In operation the vent unloader or pilot valve sends a pressure signal to the TC at the cut-out setting. This causes the TC piston to extend the control cable which pushes the throttle lever causing the engine to idle down. At the cut-in setting the pressure signal going to the TC is vented allowing the spring to return the piston cable and throttle lever to the original full speed position.
