VALVE STRUCTURE OF VAPORIZER OF AUTOMOBILE USING LPG AS FUEL

摘要

PURPOSE: A valve structure of vaporizer of automobile using liquified petroleum gas(LPG) as a fuel is provided to reduce a whistle noise caused between a valve seat and a valve head while minimizing the contact area between the valve head and the valve seat. CONSTITUTION: A valve structure of vaporizer in which a lever rotates by a vertical movement of a diaphragm and a valve head moves up and down from a valve seat so as to open/close the valve, the valve structure comprising a valve seat(53) of which upper surface(54) to be contacted with a valve head(52) has a reduced width such that a friction with a high speed LPG flow is reduced
