Abstract

A manually operated actuator for a pump employs a vertical hollow chamber. A piston is vertically slidable in the chamber between a bottom position at which no pumping action can take place and a top position at which pumping action can occur. The piston and the chamber are contained in a housing. A trigger is pivotally secured in the housing and is connected to the piston. The trigger has a first position at which the piston is held in the bottom position and has a second position at which the piston is held in the top position. The trigger is normally in the first position and is manually movable into the second position. A spring device is disposed in the housing, being secured to the trigger and spaced from the chamber and piston. The device biases the trigger into the first position whenever there is no manual pressure on the trigger.
