A piston-type compressor is provided with a lubricating system for allowing passage of blowby gas from a piston chamber to a crank chamber, which is disposed opposite the piston from the piston chamber. A driving mechanism is disposed in the crank chamber and is coupled to the pistons to move the pistons in a reciprocating motion. The lubricating system may comprise at least one groove formed in an inner surface of at least one of the cylinders to allow passage of a fluid and a lubricating oil, via blowby gas, from the piston chamber to the crank chamber. The fluid may lubricate the moving parts of the driving mechanism.
