FUEL VALVE

Document Type and Number:

WIPO Patent Application WO/2012/073569

Kind Code:

A1

Abstract:

The objective of the present invention is to adjust the flow volume of a fuel or the like to combustion equipment with good precision while using a simple construction. Two V-grooves (12, 12) for liquid fuel adjustment and air adjustment are formed in the circumferential direction in the cylindrical surface of a cylindrical flow volume adjustment member (11). In addition, the respective exhaust-port-side O-rings (19) of a liquid fuel transport pipe (9) and an air transport pipe (10) abut against this cylindrical surface. When this flow volume adjustment member (11) rotates around its axis and the O-rings (19) are positioned so as to straddle the V-grooves (12), a flow path through the fuel flow paths (4, 5) is formed between the exhaust port of each transport pipe (9, 10) and the V-grooves (12), and the liquid fuel (L) and the air (A) flows therein. The location where both V-grooves (12, 12) are formed, as well as their depth and width, are determined in accordance with the ignition operation (preheating process), normal combustion (from high heat to low heat), and the exhaust operation, and the flow volume of the liquid fuel (L) and the air (A) can be adjusted synchronously.
