Document Type and Number:
Japanese Patent JP7202647
Kind Code:
B2
Abstract:
To provide a multi-hole nozzle which is useful for spraying or injecting a fluid in a circumferential direction without adopting a rolling mechanism, and a spray method.SOLUTION: A multi-hole nozzle comprises: a nozzle body 1 having a closed tip; a plurality of slit injection ports (or spray holes, discharge holes) 3a to 3f for injecting a fluid, which are formed in a peripheral wall of the nozzle body 1; and a plurality feed passages 2a to 2f for feeding the fluid to the above injection ports respectively, which are formed in the nozzle body 1. A length (depth from the injection port) D from a terminal end of the feed passage 2a to 2f to a center axis of the injection port 3a to 3f is so formed as to be constant, and also a length Ld from an intersection point of the center axis of the feed passage 2a to 2f and the injection port to the injection port 3a to 3f is so formed as to be constant. In addition, a length L1 to L3 from a starting end of the feed passage 2a to 2f to the intersection point is so formed as to be longer than the length Ld of the injection port.SELECTED DRAWING: Figure 1
