See full text

A fluid dispensing device comprises a housing body, a reciprocating piston fluid pump, a primary drive element, a wobble assembly and a spray tip. The reciprocating piston fluid pump has a piston disposed within a pumping chamber inside the housing body. The primary drive element is coupled to the housing body to provide a rotary input. The wobble assembly connects the primary drive element to the reciprocating piston fluid pump to convert the rotary input into reciprocating input to the piston. The spray tip connects to an outlet of the pumping chamber.
