A combined liquefied gas evaporator-gas pressure regulator comprises a housing (1) having inlet (2) and outlet (15) fuel conduits connected respectively to high pressure (A) and low pressure (B) reduction chambers in the housing with a first spring loaded valve (10, 11, 12) being provided between the two reduction chambers and with the two reduction chambers additionally being communicable through a third chamber (C) for use during idling of an internal combustion engine to which connection of the outlet fuel conduit is made, in use, which third chamber includes control means (18, 19) for closing off entry thereinto of gas from the high pressure reduction chamber which is itself provided with preheating means for liquefied gas supplied as fuel, in use, to the inlet fuel conduit (2) to promote evaporation of the liquefied gas in the high pressure reduction chamber, a second spring loaded valve (3, 4, 5) communicating the high pressure reduction chamber (A) with the inlet fuel conduit (2) in which regulator, each of the high pressure and low pressure reduction chambers and the third chamber is spanned by a diaphragm, with the diaphragms (6, 13) in the high pressure and low pressure reduction chambers being positioned to actuate operation of said first spring loaded valve and the control means (18, 19) for closing off communication between the high pressure reduction chamber (A) and the third chamber (C) a control (22) screw disposed below the diaphragm (18) of the third chamber and drivable by spring means (19) against the diaphragm of the third chamber. <IMAGE>
