<p>A Combustion engine comprising an inlet duct (25) including a control-valve (27) and a vaporizer-pressure regulator having a first space divided into two parts (3,4) by a diaphragm (2) contained in said space, said diaphragm being provided for actuating a first shut-off valve (10) co-operating with a gas supply orifice of the first space, whilst the part (3) of the space in which the gas supply orifice opens out is connected through a connecting duct (13) with a second space (14) comprising a member affecting the gas pressure, said space communicating with the inlet duct (25) of the combustion engine, whereby that part (4) 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 downsteam and upstream of the control-valve (27) with the inlet duct of the combustion engine through ducts (48,41,45) including means (46,47) acting upon the size of the passage of the ducts in dependence on the load of the combustion engine occurring during operation.</p> |
