Manually-operated spray applicator |
摘要 |
A manually-operated spray applicator for discharging a coating fluid is comprised of a receiving chamber having inlet and outlet ports for respectively admitting and discharging coating fluid under pressure developed by a jet of air issuing slightly upstream of the receiving chamber and created upon the manual stroke of an air-compression piston; a closed compression chamber isolated from the receiving chamber within which the airjet is developed; and a stroke-responsive sealing stem having a central airway with an air jet orifice in registration with the discharge area of the outlet port, which airway is in communication with the compression chamber; wherein the sealing stem is adjustably reciprocable along a line from a biased sealing position closing the outlet port at the beginning of a stroke on the piston, to a retracted position with the airjet removed to a preselected position slightly upstream of the outlet wherein the sealing stem returns to its sealing position prior to the completion of that stroke.
