Manually actuated pump |
摘要 |
An improved manually actuated pump is disclosed for dispensing a volume of liquid from a container comprising a body having a cylindrical body surface. A piston is disposed within the body for slidably sealing with the cylindrical body surface 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 a 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.
