ABSTRACT:
An integrally cast compressor head includes an air inlet port communicating with a first configurated channel having filter means therein, which channel communicates with a one-way valve coupled to the surface of the head forming the top of the compressor chamber when the head is positioned on a cylinder. The integral head construction further includes a one-way outlet valve communicating with a second channel including a filter element, and an outlet port permitting pressurized air in the compressor chamber to exit therethrough. The improved compressor head construction includes a removable cover plate in sealed engagement with one side of the channels and filter means to permit ready access to the filter elements and the valves without removing the head from the compressor cylinder.
