Abstract
A sprayer nozzle includes a housing having a center bore to receive water, and a rotor having a center hole to receive a pivot shaft which may rotatably secure the rotor to the housing. The pivot shaft is offset from the center bore of the housing, and the rotor includes a number of passages disposed around the center hole of the rotor, and arranged to be selectively aligned with the center bore of the housing when the rotor is rotated relative to the housing, to allow the water from the center bore of the housing to selectively flow out through either of the passages of the rotor, and to form different water spraying patterns.
Claims10
A sprayer nozzle comprising:
- a housing including a center bore formed therein to receive water to be sprayed,
- a rotor including a center hole formed therein, and including a plurality of teeth formed thereon,
- a pivot shaft engaged through said center hole of said rotor and attached to said housing, to rotatably secure said rotor to said housing, said pivot shaft being offset from said center bore of said housing, and said rotor including a first passage and at least one second passage formed therein and disposed around said center hole of said rotor, and arranged to be selectively aligned with said center bore of said housing when said rotor is rotated relative to said housing, to allow the water from said center bore of said housing to selectively flow out through either of said first passage or said at least one second passage of said rotor, and
- means for rotating said rotor relative to said housing, said rotating means including a control ferrule rotatable attached to said housing and including a plurality of teeth formed therein and engaged with said teeth of said rotor, to rotate said rotor relative to said housing when said control ferrule is rotated relative to said housing.
