Abstract

Improvements in self-directed membrane valves comprising two rigid molds and an elastic membrane interposed between the substantially planar conjugate connecting surfaces of these shells to form a peripheral socket, the first shell having an inlet and an outlet pipe that opens into the membrane by holes susceptible to being isolated from each other by this, while the second shell delimits a control cavity closed by this membrane and connected by a permanent communication conduit to the inlet branch pipe and by a pilot conduit to the outlet branch pipe.
