ABSTRACT:
A gas-operated internal combustion engine which includes a volume control valve for a gas supplied to an air/gas mixer. An air filter is arranged within a charged air supply arrangement and, between a diaphragm of the volume control valve in a section of the air charge supply, a pressure equalizing connection is provided which, starting from the air filter or from the air/gas mixer and extending in a direction toward the volume control valve includes a throttle and a blocking biased check valve. A conduit branches off in the pressure-equalizing line at a point between the air filter and the check valve, with the conduit leading through a diaphragm operated valve to the intake manifold. The valve is controllable by the intake manifold vacuum such that the conduit is blocked with a high value intake manifold vacuum and opened with a low value intake manifold vacuum. The conduit may also branch off from the pressure equalizing line at a point between the check valve and volume control valve with the conduit leading through two series connected diaphragm operated valves controllable by the intake manifold vacuum.
