Abstract

PURPOSE: To cause pumping action, by moving a flat piston having projections and recesses alternately and a cylinder having a shape similar to that of the piston, relatively to each other.
CONSTITUTION: A piston is cruciform and flat and has projections and recesses regularly located. A cylinder 2 has a shape similar to that of the piston 1. When a crankshaft 5 is driven through a pulley 18, the piston whirls clockwise. At that time, a liquid flows from a pump chamber 3 through a discharge port 13, pushes up a check valve and flows into a dischage chamber 11. As a result, a high-pressure fluid is supplied to the outside through a discharge connection port 16. In that case, a fluid is introduced into a suction space from the outside through a suction connection port 15, a suction chamber 10 and a suction port 12. Pumping action is thus caused.
