Abstract:

A duel-cylinder reciprocating rocking piston-type compressor is disclosed with side foot mounts resulting in reduced compressor vibration and noise. An optimum vertical height for the foot mounts as well as an optimum lateral or axial position along the compressor body relative to the piston connecting rod are also disclosed. Specifically, the side foot mounts are mounted to the housing at a height falling in the range of 0.5 times the height of the drive shaft to about 1.5 times the height of the drive shaft. Further; an elevated o-ring gland or gasket is disclosed for sealing the heads to the valve plates. Still further, and improved valve plate design is disclosed that includes substantially flat valve plates, monolithically connected together through a raised central portion that defines tubes or passageways connecting the intake and output chambers associated with each cylinder. The result is a compressor with a shorter vertical height, that is lighter and that produces less noise and vibration without compromising output.
