ABSTRACT:
An accumulative pressure pump that has upper and lower pressure chambers of different diameters, each of which is provided with a piston having a connected stem. Inlet and outlet check valves are provided. The outlet valve opens on accumulation of pressure on the downward stroke of the two pistons. The lower portion of the inner sidewall of the lower chamber is provided with a rib or a recess to permit any air trapped in the two chambers to be expelled through a bottom opening that is provided in the lower chamber. The dip tube is connected directly to the second piston and has its end abutting or adjacent the bottom of the container and is reciprocal with the second piston whereby its lower end moves into the lowermost portion of the container to permit substantial removal of the entire contents of the container.
