ABSTRACT:
A combustion engine includes an inlet duct including a control valve. A vaporizer-pressure regulator for use with the combustion engine has a first space divided into two parts by a diaphragm contained in the space, the diaphragm actuating a first shut-off valve co-operating with a gas supply orifice of the first space, while the part of the space in which the gas supply orifice opens out is connected through a connecting duct with a second space comprising a member affecting the gas pressure, the space communicating with the inlet duct of the combustion engine, whereby that part of the first space which is located on the side of the diaphragm actuating the first shut-off valve remote from the first shut-off valve is connected both downstream and upstream of the control valve with the inlet duct of the combustion engine through a pressure duct network including means acting upon the size of the passage of the ducts in dependence on the load of the combustion engine occurring during operation.
