Pressure regulator for combustible gases, in particular for internal-combustion motors

摘要

The purpose of the pressure regulator is to feed internal combustion motors or engines with combustible gases and it comprises two membranes 14 and 16 which respond to the intake suction of the motor, while the second of the said membranes actuates dislocating members 22 to check the communication between the said chambers A2 and A3 delimited by the said membranes and connected with the utilizer by means of a duct 30. One gauged nozzle 64 delivers part of the combustible gas into chamber A3 interested by the second membrane 16 and which is directly connected with the suction 30 of the motor or engine.
