Abstract
Membrane pump intended, more particularly, for the pumping of liquefied gases, comprising, in a body, a pump diaphragm and a control rod mounted on a eccentric shaft, driven by a motor and transmitting to the membrane an alternative displacement practically rectilinear, and in a cap suction and discharge valves, characterized by the fact that a second membrane, called safety, is added by the side facing the atmosphere of the pump membrane, in order to form between the two membranes a space without communication with the outside, this safety membrane being mounted in such a way that, for an equal stroke of the two membranes, its unit displacement is smaller than that of the pump membrane.
