Abstract
Gas meter device of the type in which a housing, provided with an intake pipe and an exhaust pipe, contains one or more boxes with bellows, each of them being constituted by two measuring chambers separated by a membrane mobile and placed alternately in communication with the inner enclosure of the enclosure fed by the intake pipe and with the exhaust pipe, by means of a sliding or valve device operated by the membrane, said meter being characterized in that each measuring chamber presents at least one opening opening into the interior enclosure of the enclosure, each opening being provided with a valve actuated by a spring, opening said normally closed valve when it is subjected to a pressure difference comprised between the necessary pressure difference at full load for the control of the membrane and the pressure difference for which a deformation period of the measuring chamber.
