Abstract
A cam driven compressor includes a cam coupled to a plurality of cylinder and piston assemblies. Each cylinder and piston assembly comprises a piston located and movable within a respective cylinder. Each cylinder has a cylinder head. The compressor comprises a housing defining a cavity configured to receive a portion of a source gas from one or more of the cylinders in order to maintain a positive gas pressure within the cavity.
Claims10
A cam driven compressor, wherein a cam is coupled to a plurality of cylinder and piston assemblies wherein each cylinder and piston assembly comprises a piston located and movable within a cylinder, each cylinder having a cylinder head, the compressor comprising a housing having a first block half attached to a second block half along a longitudinal plane and defining a sealed cavity therebetween, wherein each cylinder and piston assembly is located along said longitudinal plane and extends radially outwardly from the housing in spaced relation with a next successive cylinder and piston assembly of the plurality of cylinder and piston assemblies, wherein each cylinder and piston assembly is in fluid communication with the sealed cavity, and wherein the sealed cavity is configured to receive a portion of a gas exclusively from one or more of the cylinder and piston assemblies to thereby pressurize the sealed cavity of the housing.
A method of producing a high purity high pressure gas, comprising:
- a) providing a cam driven compressor, wherein a cam is coupled to a plurality of cylinder and piston assemblies wherein each cylinder and piston assembly comprises a piston located and movable within a cylinder, each cylinder having a cylinder head, the compressor comprising a housing having a first block half attached to a second block half along a longitudinal plane and defining a sealed cavity therebetween, wherein each cylinder and piston assembly is located along said longitudinal plane and extends radially outwardly from the housing in spaced relation with a next successive cylinder and piston assembly of the plurality of cylinder and piston assemblies, wherein each cylinder and piston assembly is in fluid communication with the sealed cavity, and wherein the sealed cavity is configured to exclusively receive a portion of a gas from one or more of the cylinder and piston assemblies to thereby pressurize the sealed cavity of the housing;
- b) allowing the source gas to be supplied to the compressor;
- and
- c) allowing a portion of the source gas to pressurize the sealed cavity of the housing.
