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.

A baffle, for directing air within a compressor head, includes a first leg extending along a first direction, positioned proximate to a first valve of the compressor head, and a second leg extending along the first direction and substantially parallel to the first leg, positioned proximate to a second valve of the compressor head. A first portion of air from a first side of the first leg is communicated to a second side of the first leg beyond an end of the first leg. An aperture in the first leg communicates a second portion of the air from the first side of the first leg to the second side of the first leg. A turbulence and/or pressure fluctuation proximate the first valve is reduced by communicating the second portion of the air from the first side to the second side of the first leg.

System and method for reducing at least one of airflow turbulence and pressure fluctuation proximate a valve

A compressor crankcase assembly is provided for an air compressor. In one example, a compressor crankcase assembly includes a crankcase made of a material comprising at least 50% by weight aluminum and a crankcase liner disposed within the crankcase. The crankcase has a protrusion that is at least partially disposed within the groove of the crankcase liner.
