Abstract
A sprinkler nozzle capable of forming various sprinkling patterns. An inner cylinder laterally surrounds an outer periphery of a nozzle body, a gap within the inner cylinder serves as an inner flow passage, and an outer flow passage is provided outside the inner cylinder. Water from through holes formed in a peripheral wall of the nozzle body is conducted to the inner flow passage or the outer flow passage by operating reciprocatingly the inner cylinder. Further, an enlarged tip end portion formed at its peripheral wall with water flow-in holes is provided contiguous to a closed tip end of the nozzle body, and the water flow-in holes communicate with the inner flow passage so that an operation of the inner cylinder can provide various sprinkling patterns such as a straight rod, mist, cone, watering pot and shower.
