ABSTRACT:
An improved manually actuated pump is disclosed for dispensing a volume of liquid from a container, comprising a body having a duct with a duct conduit communicating with the body. A piston is disposed within the body for slidably sealing with the duct to define a pump chamber with at least a portion of the piston being disposed external to the body defining a piston stem having a stem passage extending therethrough. A spring biases the piston into an extended position. An induction tube is received within the duct conduit for providing fluid communication between the liquid within the container and the pump chamber. A first one-way valve enables the flow of the liquid only from the container into the pump chamber whereas a second one-way valve enables the flow of the liquid only from the pump chamber into the stem passage. An actuator having a terminal orifice communicates with the stem passage for discharging a volume of the liquid from the container through the terminal orifice upon a longitudinal movement of the actuator from the extended position to a retracted position by an operator.
