Abstract
A gas-operated internal combustion engine which includes an air/gas mixer and a volume control valve for feeding gas to the air/gas mixer. The volume control valve is normally biased into a closed position and includes a diaphragm adapted to be exposed on an operating side thereof to a vacuum ambient in the gas downstream of the volume control valve so as to urge the diaphragm to opening position of the volume control valve. A rear side of the diaphragm is adapted to be exposed to a control pressure. A pressure compensating connection is provided between the rear side of the diaphragm and a portion of the air supply system of the engine and terminates at or upstream of the air/gas mixer. A choke is arranged in the pressure compensating connection at either an air filter of the air supply system or a housing of the air/gas mixer with a check valve being disposed in the pressure compensating connection at a position between the choke and the volume control valve. A branch conduit branches off the pressure compensating connection at a position between the check valve and the volume control valve with a reversing valve being arranged in the branch conduit for selectively controlling th…
