Abstract
A fluid sprayer includes a rigid fluid conduit with a conduit side wall extending along a conduit axis between open first and second conduit ends. The conduit side wall defines a fluid passage extending between the open first and second ends. A spray nozzle with a fluid-expulsion bore is connected to the second conduit end such that it can pivot about a nozzle-pivot axis that extends orthogonally to the conduit axis and such that fluid introduced into the first conduit end is expelled through the fluid-expulsion bore. A nozzle actuator is attached to the conduit for bi-directional rotation about an actuator-rotation axis having a component of spatial extension perpendicular to the conduit axis. The nozzle actuator and nozzle are mechanically linked so that rotation of the actuator causes the nozzle to pivot with respect to the conduit axis. A spray-angle selector rotates in tandem with the nozzle actuator and includes an angle-selection surface. A selector stop, with a base portion fixed relative to the fluid conduit, cooperatively engages the angle-selection surface to define a plurality of angular nozzle positions and provide resistance opposing pivotal movement out of each angul…
