摘要： A reciprocating air brake compressor includes a crank case housing a crank shaft and a piston assembly operatively connected to the crank shaft via a connecting rod. The piston assembly includes a piston moveable within a bore of the crank case, a piston ring disposed on a peripheral surface of the piston, and a wrist pin rotatably connecting the connecting rod to the piston. A means is provided for generating an air stream free of oil. In one embodiment, the means includes a channel extending through the crank shaft and connecting rod for delivering oil to the crank shaft and wrist pin bearings. The means further includes first and second sealing assemblies disposed adjacent the crank shaft and wrist pin bearings respectively. In another embodiment, the means includes crank shaft bearings and wrist pin bearings packed and sealed with grease. In another embodiment, the means includes crank shaft bearings packed and sealed with grease and wrist pin bearings and the piston ring being lubricated with a lubricant injected through a passage of the compressor.
