Abstract
A paint gun assembly including a spray head and a connecting manifold. The spray head includes a bore terminating in a radially extending space of gradually increasing radius. The bore receives a shaft that has an axially extending bore which connects with radially extending bores in which balls are contained. The shaft also contains a plunger with a rounded end, engaging the balls. When forced into the axial bore, the plunger forces the balls into the radially extending bores and out into the tapered, radially extending space. The plunger engages a cam which is exposed at a surface of the manifold body and includes a hexagon drive to adjust the angular rotation of the cam using a suitable key. The manifold body provides a recess for receiving a retaining pin, whose end is received in the cam guide profile. Axial movement of the cam is resisted by a compression spring.
