ABSTRACT:
A device for controlling the quantity of a medium, such as paint, lacquer or adhesive emerging from a discharge nozzle of an equipment, such as a spray gun, which device includes a delivery chamber extending between the discharge nozzle and a pump housing which has a pump chamber connected at one end by an outlet valve to the delivery chamber and receives a reciprocating pump piston, with the delivery chamber including a control arrangement that will adjust the quantity of the medium flowing through the discharge nozzle and also prevent a dribble from the end of the nozzle during a return stroke of the pump piston. The control arrangement includes a control sleeve which telescopically receives the control piston that moves with the valve member of the outlet valve relative to the sleeve and the sleeve and control piston have a flow restricting arrangement, such as formed by a groove having a different cross sectional size in the axial direction so that the size of the opening will change as the control piston moves relative to the control sleeve.
