Claims

[Claims for Utility Model Registration] 1. A slow speed fuel passage is provided in the primary decompression chamber of the regulator, and the slow speed fuel passage is connected to the first fuel supply path for starting, idling, and light load operation, and for light and medium-duty vehicles. A switching valve is provided that branches into a second fuel supply path for load operation and alternately opens and closes both supply paths, and the slow speed fuel path is provided with a switching valve that collectively controls the fuel flow rate supplied to both of the supply paths. The first fuel supply passage is provided with a fuel throttle that controls the fuel flow rate, and the switching valve is provided with a fuel throttle that controls the first and second fuel supply in relation to the opening degree of the throttle valve. 1. A slow speed fuel supply device for an LPG vaporizer, characterized in that an opening/closing means for alternately opening and closing a passage is provided. 2 Utility Model Registration Scope of Claim 1 The slow speed fuel passage as set forth in claim 1 is directly communicated with the switching valve, the first and second fuel supply passages are branched from the switching valve, and the fuel in the slow speed fuel passage is communicated directly with the switching valve. A slow speed fuel supply device in an LPG vaporizer, in which a throttle is provided in a slow speed fuel passage portion located in a regulator.
