Abstract

Improvements applied to alternative diaphragm pumps, more particularly fuel supply pumps for internal combustion engines, on the recoil duct in which an expansion chamber containing a fluid is connected directly to the recoil hatch It is compressible and is sealed by a flexible impermeable membrane that separates the said incompressible fluid from the liquid moved by the pump, characterized by the fact that this expansion chamber is such that it has a medium pressure (that is, a pressure measured with appliance stopped) above atmospheric pressure.
