Plastic spray nozzle with improved distribution

摘要

A plastic part circle irrigation sprinkler (10) of the spray head type is described having a generally cylindrical body formed of molded plastic and defining a lower end portion (26) and an upper end portion (30) interconnected by a central portion (28) having an outer cylindrical surface. The lower end portion is adapted to be coupled to a source of pressurized water. The upper end portion defines a deflector cap (30) having a generally pie-shaped laterally outwardly (22) diverging deflector recess formed in a peripheral portion thereof and adapted to deflect water laterally outwardly away from the body as a generally high pressure, high velocity fan-shaped spray (23). A generally vertically directed water passageway extends through the body for providing a water flow path between the pressurized water source and the deflector recess. A secondary water spray outlet (24) is formed in said outer surface of said body below said deflector surface and coupled with said water passageway through said body by a generally laterally directed tortious pathway formed to divert a portion of the pressurized water flowing through said water passageway to said secondary spray outlet (24) and to disburse said diverted water portion (25) laterally outwardly away from the body as a generally low pressure, low velocity water spray.
