Abstract
A fluid sprayer includes a pump motor, a piston, a pump housing, and an outer housing. The piston is reciprocatable by the pump motor. The pump housing comprises a pump chamber housing disposed to receive the piston, and a plurality of alignment pins extending laterally away from the pump chamber housing. The outer housing surround and anchors the pump motor, and has a plurality of internal lateral bores disposed to slideably receive and retain the alignment pins, such that the pump housing is free to self-align with the piston.
