PURPOSE: A regulator is provided to prevent the occurrence of icing on a first pressure reducing part according to the property of a natural gas fuel, and to miniaturize the size of a product by simplifying an inner structure. CONSTITUTION: A regulator includes a body(10), a first pressure reducing part, and a second pressure reducing part. The body forms an exterior and a frame, and has a first chamber and a second chamber through which the pressure of gas fuel is reduced into a predetermined discharge pressure with two steps. The first pressure reducing part is installed inside the body, and firstly reduces the high pressure of the gas fuel. The second pressure reducing part is installed to be connected to the first pressure reducing part in series inside the body, and secondly reduces the pressure of the gas fuel which is transferred from the first pressure reducing part. The body includes a supply port, a transferring path, a first body(11), a second body(12), and a cover(13). The gas fuel is supplied to the supply port. The gas fuel, of which the pressure is reduced in the first pressure reducing part, is transferred to the second pressure reducing part through the transferring path. A hot water path, in which hot water moves, and a first orifice, which firstly reduces the pressure of the gas fuel, are formed in the first body. The second body is connected to the first body, and receives a gaseous state of the gas fuel through the transferring path. The cover covers the rear side of the second body. |
