Claims

[Claims for Utility Model Registration] 1. An air bleed mechanism comprising a mixing pipe for mixing air into the fuel upstream of the main nozzle, which includes:
A vaporizer characterized by being provided with a check valve that only allows flow from the bottom to the top, and the check valve being configured to open by the buoyancy of large bubbles generated and grown at the bottom of the mixing pipe. . 2. The check valve according to Claim 1 of the Utility Model Registration has a sheet with a small circulation hole formed in the center fixed in the mixing pipe, and a ball valve whose specific gravity is slightly larger than the specific gravity of the fuel is attached to the top of the sheet. A vaporizer is provided with a bubble collection chamber on which a peripheral wall is provided on the lower surface of the outer periphery of the sheet and an air bubble collection chamber whose lower surface is open.
