Piston fluid pump - has two chambers divided by movable wall allowing variable compressed volumes in both chambers

摘要

A piston stroke fluid pump has two chambers divided by a movable wall. The two chambers (2, 3) have a connection between them, which prevents fluid flow in one direction. A compressed volume in the first chamber causes a certain movement in the wall, which is different to the movement caused by a compressed volume in the second chamber. The two chambers are defined by the wall in a first cylinder, the movable wall being that of a first piston in the cylinder. ADVANTAGE - Pulsation and vibration reduction.
