ABSTRACT:
An apparatus is disclosed for a variable restrictor for a manually actuated pump for dispensing a liquid within a container comprising a body having an internal cylinder secured to the container. A piston is slidably disposed within the internal cylinder of the body having a stem end extending external to the body. The stem end supports an actuator having a terminal orifice communicating with an internal stem passage of the pump stem for discharging the liquid from the container through the terminal orifice upon movement of the actuator from an extended position to a retracted position. The variable restrictor is provided for varying said retracted position to reduce the longitudinal movement of the actuator from the extended position to the retracted position for reducing the volume of liquid discharged from the terminal orifice.
