  • Compact compressor
    Patent number: 7491040
    Abstract: A compact compressor including one or more heads. Each of the compressor heads is configured with at least one of the intake and output valves incorporated into the piston head. The compact compressor also has a cylinder with a reduced mass, increased surface area, and metal to metal contact with the housing for greater dissipation of heat generated by the compressor.
