Abstract
A combination airless paint pump and air compressor wherein a prime mover drives an eccentric cam wheel within an oil reservoir housing. A piston, movably received within a housing bore is engageable with a periphery of the cam wheel to load an hydraulic column open to the piston cylinder for oscillating a paint spray pump diaphragm. A second piston member, received in a bore open to the housing, is engageable with the periphery of the cam wheel spaced circumferentially of the paint pump piston. The second piston is operatively connected with an air pump diaphragm. Selector means are provided to disengage, selectively, either one of the pistons from contact with the cam wheel whereby the unit can operate in a paint only mode, an air only mode or a combination air and paint mode.
