US 2015/0306608 A1 · Adjustable Pattern and Adjustable Flow Nozzle

Abstract

A spray nozzle includes a stem, a shaper, and a plunger. The stem has first and second portions and defines a first bore along a center axis. The second portion defines a second bore along the center axis and at least one conduit adjacent the bore. The first bore is in liquid communication with the second bore and the at least one conduit. An outer surface of the stem defines a first limit feature. The shaper collar is movably received over the stem. The shaper collar defines a second limit feature that complements the first limit feature. The contact between the limit features limits the travel of the shaper collar. The plunger has a head and a tail. The head is received in the first bore and is impassible through the second bore. The tail is received through the second bore and defines a retention feature.

A spray nozzle comprising:

a stem defining a center axis and a center bore therethrough along the center axis, the center bore having a first portion defining, at least in part, a frustoconical shape and a second portion defining a cylindrical shape, the stem defining liquid bores arranged around the second portion of the center bore, each liquid bore in liquid communication with the first portion of the center bore, the stem defining a first limit feature;
a shaper collar movably received over the stem for movement along the center axis, the shaper collar defining a second limit feature complementary to the first limit feature, contact between the first and second limit features limiting travel of the shaper collar along the center axis;
and
a plunger movably received in the center bore of the stem, the plunger having a head received in the first portion of the center bore and a tail received through the second portion of the center bore, the head defining a frustoconical shape capable of seating against the first portion of the center bore and impassible through the second portion of the center bore, movement of the head altering a flow rate through the stem, the plunger defining a retention feature;
and
a retainer received by the retention feature, the retainer preventing escapement of the plunger from the center bore.
