A multi-purpose window-washer sprayer with orientable jet, in particular for vehicles

Described herein is a window-washer sprayer (1), which can be installed on a vehicle for cleaning the windscreen/rear window and/or a headlamp of the vehicle, designed to provide an orientable jet, either atomized or filiform, by substitution of a cylindrical nipple (3) installed laterally via snap-action, idle and fluid-tight, within a seat of an enbloc sprayer body (2), which can be constrained to the vehicle. The sprayer body (2) defines the seat (4), an internal duct (5) for passage of a detergent fluid, and a side window (6) made in a position corresponding to the seat (4) and partially occupied in use by the cylindrical nipple (3). The internal duct (5), the seat (4), and the nipple (3) have a geometry such that when a flow of detergent fluid is fed into the internal duct it splits by fluid-dynamic effect into a number of separate flows that simultaneously reach the seat and are expelled through a through radial slit (10a) or a plurality of through radial holes (10b) selectively made in the cylindrical nipple (3) in a position corresponding to the side window (6) of the sprayer body.
