Claims

[Scope of utility model registration request]

A fixed bench lily equipped with a main nozzle that spouts fuel introduced from the main jet, a variable bench lily equipped with a power nozzle that spouts fuel introduced from the power jet, a suction chamber communicating with the variable bench lily, and an atmosphere. a partition member that airtightly partitions the suction chamber from the open pressurized chamber; and a partition member that is integrally formed with the partition member and that slides due to the pressure difference between the suction chamber and the pressurized chamber to open the variable bench lily. a piston capable of increasing the opening area; a jet needle fixedly attached to the piston and capable of changing the opening area of the power nozzle as the piston slides; one end communicating with the suction chamber and the other end communicating with the atmosphere. and a passageway provided in the middle of the passageway that opens when the operating temperature of the engine is below a certain temperature to open the suction chamber to the atmosphere, thereby stopping the piston in a closed state and causing fuel to be ejected from the power nozzle. A vaporizer characterized by being equipped with a thermo valve that suppresses
