Abstract:
1. A gas combustor, comprising: a gas intake valve, a bottom of a valve tube axially formed in a valve member being installed with a filter member, a first spring being installed above said filter member and inside said valve tube, the top of a valve pin being protruded out of a tube opening formed at and communicated with the top of said valve tube, a plug outwardly protruded at the bottom of said valve pin being abutted against said first spring, said plug being enabled to seal said tube opening through said first spring being stretched, and when the top of said valve pin being axially subject to a force, said valve pin and said plug being downwardly moved, said first spring being compressed thereby enabling said tube opening to be opened; and a base, a bottom and a top of said base are axially and respectively formed with a connection hole connected with a gas tank and a combination hole connected with a pressure stabilizing device, a neck hole having a smaller caliber and allowing said gas intake valve to be installed is formed between and communicated with said connection hole and said combination hole; wherein a vaporizing chamber is formed between said gas intake valve and said pressure stabilizing device, said vaporizing chamber is laterally in communication with a gas discharge port radially formed in said base; wherein said pressure stabilizing device includes: a diaphragm, which is an elastic sheet member made of a polymer material, the periphery thereof is connected to a block wall protruded at the bottom of said combination hole, so said vaporizing chamber is formed between the bottom of said diaphragm and said gas intake valve of said neck hole; wherein, the bottom of said diaphragm is provided with a passive member connected with said valve pin at the top of said gas intake valve, the top thereof is provided with a support member; and a position limiting piece, said position limiting piece connected between said diaphragm and a fasten seat and having a center protruding axially; and a regulation seat, rotationally screwed in the fasten seat, and a shaft rod formed at the top is protruded out of an opening formed at the top of said fasten seat, said fasten seat is fastened in said combination hole of said base, the bottom periphery of said fasten seat is served to press the periphery of said diaphragm against said block wall formed at the bottom of said combination hole; and a second spring is installed between an inner wall at the top of said regulation seat and said support member; through rotating said regulation seat, said regulation seat is enabled to be axially ascended/descended in said fasten seat so as to compress or stretch said second spring disposed between said regulation seat and said support member at the top of said diaphragm for adjusting the pressure; when the pressure supplied by said second spring to said diaphragm is greater than the pressure of said first spring and the fuel in said gas intake valve, and when the pressure supplied by said second spring to said diaphragm is smaller than the pressure for vaporizing fuel in said vaporizing chamber, said diaphragm, said support member and said passive member reciprocally and synchronously drive said valve pin of said gas intake valve and said plug at the bottom to axially move, thereby enabling said tube opening at the top of said gas intake valve to be opened or sealed, so as to adjust the pressure of fuel entering said vaporizing chamber and to adjust the flow of vaporized fuel gas flowing towards said gas discharge port.
