ABSTRACT:
A compressor includes an air cooled lubricant temperature regulator and an engine for providing motive force to the compressor. A first, electric-driven, self-priming pump provides a supply of lubricant to the compressor prior to starting the engine and for a predetermined period of time after the engine is operating. The first pump is flow connected in fluid receiving relation with a lubricant reservoir. A first electronic controller means directs compressor operations, including directing operation of the first pump. A second electronic controller, external to the first controller means, directs operation of the first pump after engine operation. A second, compressor-driven, self-priming pump provides a primary lubricant pumping function during engine operation at predetermined run speeds. A valve means is flow connected intermediate the discharge of the first pump and the discharge of the second pump for preventing lubricant cross flow between the first and second pumps during simultaneous operation thereof. The first pump preprimes the second pump to facilitate the self-priming duty of the second pump.
