ABSTRACT:
A flow control device for a fluid dispenser provides independent adjustment and control of both stroke length and spring load of a needle valve which ultimately controls outward flow from a nozzle. Independent adjustment and control of stroke length and spring load enable an operator to independently set the dispensing gap which is directly proportional to dispensing rate, and the closing force of the needle valve so that a single dispenser may be used for dispensing materials of different viscosity. An axially movable stop member is aligned with a piston carried by the needle valve. A compression spring circumscribes the stop member, and a cylindrical retainer surrounds the compression spring. An axially adjustable screw holds the retainer in place, thereby holding the spring in compression between the retainer and the piston. The axial positions of the stop member and the retainer may be adjusted independently to independently set stroke length and closing force.
