  "Valve having as a closing element a membrane made of a sleeve".



   The present invention relates to a valve, the closure element of which consists of a fully elastic membrane in the form of a sleeve fixed, by two ends, in the body of the valve.

   In the open position, said membrane has a passage around a member extending axially in said body of the valve, the wall of said body having, on its periphery, one or more openings making the cavity around said membrane communicate with atmospheric air while that the displacement of said membrane towards its closed position actuates a switching device which stops the drive element of a pump connected to the outlet of said valve *

The present invention reconciles this difficulty in a very simple manner by separating the casing from the switching device.

   In this execution, the dancing of a leaking sleeve-shaped diaphragm is practically eliminated because
 EMI2.5
 that no connecting element attaches to said mambrana. If, however, a leak should occur, 10 * au will not be able to reach the switching device.
