A compressor comprises a first compressor piston assembly including a first compressor piston head having a bottom side and a longitudinal central axis. The compressor also comprises a first nozzle arranged to direct a first oil stream towards the bottom side of the first compressor piston head to cool the piston assembly. The compressor further comprises a second nozzle arranged to direct a second oil stream towards the bottom side of the first compressor piston head to cool the piston assembly. Each of the oil streams is substantially parallel to each other and to the longitudinal central axis to provide a flow of oil to cool the piston assembly and to reduce an oil carryover by the first compressor piston assembly by up to about fifty percent as compared to a compressor having no nozzles directing oil streams towards the bottom side of the first compressor piston head.

A crankcase assembly for a reciprocating machine is provided in which a crankcase having at least one cylinder with a wet cylinder liner arranged therein. A cylinder head for charging and discharging pressurized gas is mounted on the crankcase and a cylinder head gasket for preventing leakage of pressurized gas out of the cylinder is arranged between the crankcase and the cylinder head and is running circumferentially spaced from the inner wall of the cylinder liner. A circumferential coolant channel is formed between the inner crankcase wall and an outer wall of the cylinder liner, wherein a lower sealing means is arranged between the inner crankcase wall and the cylinder liner on the crankshaft side of the coolant channel for preventing leakage of coolant fluid. An upper sealing means is arranged between the inner crankcase wall and the cylinder liner on the cylinder head side of the coolant channel for preventing leakage of coolant fluid.
