摘要： A governor for combustion engine driven compressors includes two piston members. The first piston member is actuated by oil pressure and a second piston member is actuated in an opposite direction by the compressor discharge fluid pressure. The governor is responsive to the differential between a predetermined low working pressure and the compressor discharge fluid pressure. A governor spring member acts to move a fuel control member for the engine between an idle position and full speed position. The governor spring member is subjected to power bias by the two piston members under various operating conditions. The governor includes an unloading control valve which is movable to unloading and loading positions when the fuel control member is adjacent the idle position. A compressor inlet valve and compressor vent valve are provided for loading and unloading the compressor. The second piston member controls the fuel supply in response to compressor delivery of compressed fluid when the plant is operating between an intermediate and full capacity.
