<P>PROBLEM TO BE SOLVED: To easily form a heating fluid passage and enhance heating efficiency by the heating fluid passage in a pressure reducing valve for LPG fuel including a recess for forming a heating chamber in a body incorporated with a valve mechanism for reducing pressure of the LPG fuel and leading the LPG fuel to the heating chamber therein and a heating fluid passage formed in the body to make heating fluid for heating the LPG fuel in the heating chamber flow. <P>SOLUTION: The recess 11 is formed along an inner periphery in a virtual circle C1. The heating fluid passage 70 is formed by connecting two passage portions 71, 72 arranged along each of two sides orthogonal to each other in a right-angled triangle T1 arranged with three vertexes in the virtual circle C1 so that the two passage portions 71, 72 are orthogonal to each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
