Abstract (en)
[origin: US8308447B2] A compressor piston including a piston in a cylinder; a connecting rod connecting the piston to a crankshaft in a crankcase by a roller bearing; and an air inlet line and an air outlet line in a cylinder head. A tube connection between the air inlet line and the crankcase transports cooling air from the inlet line to the crankcase. The tube connection is exterior the cylinder. An inlet valve is connected to the tube connection which opens when the pressure in the crankcase is less than the pressure in the air inlet line; and an outlet valve is connected to the crankcase which opens when the pressure in the crankcase exceeds a predetermined value.
