Abstract
A regulator for compressed natural gas is prevented from being frozen and from being heated to higher than a degree appropriate for prevention of the freezing. A hot-water passage 11 for circulating a portion of the engine cooling water is provided adjacent to a gas passage 24 equipped with a reducing valve 21 in the primary decompression section A of the regulator. A hot-water outlet member 10 is provided at the outlet aperture of the hot-water passage 11. A temperature sensitive valve 42 is mounted in the hot-water outlet member 10 and is set so that the hot-water passage 11 is closed with the valve body 48 when the temperature of the hot-water exceeds the degree appropriate for prevention of the freeze at the outlet aperture.
