摘要:
A nozzle is disclosed which has a cylindrical nozzle main body. A nozzle tip of the nozzle comprises a plurality of members formed by dividing an approximately cylindrical member in the axial direction thereof and is accommodated in the interior of the nozzle main body. A spring is provided between a spring receiving section of the nozzle tip and a wall positioned on a forward side of the nozzle main body. At least one of a peripheral surface of a discharge section of the nozzle tip and an inner surface of a tip engaging opening of the nozzle main body is tapered. A self-cleaning operation is performed when the atomization pressure is reduced, because the spring urges the nozzle tip toward a rearward side of the nozzle main body.
