Spray gun with side-mounted fan control

摘要

A paint spray gun for use in association with a HVLP turbine blower and an attachable paint container divides input air flow into two horizontally adjacent channels. Air flow through one channel remains open whereas air flow through the second channel may be varied by a side air controller such that when air flow is cut off from the second channel, the paint mixture is sprayed in a substantially circular shape whereas when air flows through the second channel the paint mixture is sprayed in a substantially fan shape. In another embodiment, a rotatable nipple is positioned to redirect some air flow from the channels to drive paint from the paint container.

主权项

1. An apparatus for spraying liquids comprising:
a barrel having
a front end having a spray head,a rear end, anda pair of side walls extending horizontally between the front end and the rear end, each side wall defining one of a left side wall and a right side wall; an air inlet port connectable to an HVLP turbine blower; a variable channel in flow communication with the air inlet port; an open channel in flow communication with, and remaining open to the air inlet port, the variable channel and the open channel extending generally horizontally side by side with respect to each other in the barrel wherein one of the channels extends adjacent to the right side wall, and the other channel extends adjacent to the left side wall; and a side air controller mounted on one of the right side wall and the left side wall and operably connected to and located within only the variable channel and rotatably mounted generally orthogonally to a side of the variable channel such that the flow of air through the variable channel is varied by the side air controller, whereas air flow through the open channel remains constant; and the spray head at the front end of the barrel mixing air, received from the variable and open channels, and fluid.
