GAS PRESSURE REGULATOR, IN PARTICULAR FOR A COMBUSTION ENGINE

摘要

The invention concerns a gas pressure regulator, in particular for supplying an internal combustion engine with a gas fuel under constant pressure, comprising a high pressure inlet (54), a valve for adjusting the gas stream of the high pressure inlet (54) towards a low pressure chamber (27) and a low pressure outlet (16) communicating with the low pressure chamber (27). The low pressure outlet (16) has a convergent/divergent shape and at least one secondary suction channel (82) which is, on one side, in communication with the low pressure chamber (27) and, on the other side, in communication with the outlet (16) at a location downstream of the surface of minimum passage of the outlet (16) so as to create a Venturi effect increasing the gas flow exiting the low pressure chamber (27).
