Problems solved by technology

This nozzle configuration will generally reliably dump a jet of washer fluid onto the vehicle's rear window or backlit glass, but is said to be no better for the jet's ability to clean any given surface
A nozzle arrangement similar to that shown in Figures 1A-1D would work well enough to clean the rear window if wiper blades were also used, but the jet from this nozzle alone would barely clean the window

Embodiment Construction

[0031] Turning now to the detailed description of the automotive trim mounted spray nozzle assembly and compact shear spray nozzle assembly of the present invention, Figure 2-Figure 11 Specific exemplary embodiments are shown for shear jet nozzle configuration and for selecting and aiming nozzles to provide a desired jet. All of the illustrated embodiments provide a very compact spray head design that reliably produces a fan spray or pattern consisting of two or three shear-shaped flat sprays in the The cleaning fluid (eg, water) is evenly distributed within the combined fan-shaped spray angles of the selected angular spread (eg, 30° to 120°). All automotive trim mounted spray nozzle assemblies and compact shear spray nozzle components (eg 100, 200, 300) of the present invention are well suited for integration into automotive exterior trim, such as mid height for use on vehicles 14 A stop lamp ("CHIMSL") assembly 10 is installed, as shown in FIG. 1A. The nozzle assemblies a...

Abstract

A very compact nozzle assembly 100, 200, 300 and spray head for an automotive washer nozzle is configured for inclusion into an automotive trim component. The compact nozzle assembly and spray head generate a very effective cleaning spray at a selected spray fan angle, yaw angle and roll angle and, in an exemplary embodiment, the spray fan is dual shear shaped, producing an even distribution, which may be varied from 30 degrees to 120 degrees. Spray head may be as small as 5mm in diameter and be aimed to provide a spray with various spray aim, yaw and roll angles. The design accounts for better mold ability and versatility of application.

Description

[0001] Related application information: [0002] This application claims priority to the following co-pending, commonly owned U.S. patent application, the entire disclosure of which is incorporated herein by reference: (a) filed on August 15, 2014, entitled " (Angled Shear Washer Nozzle), U.S. Application No. 62037942; (b) filed on August 22, 2014, entitled "Angled Shear Washer Nozzle" Nozzle), U.S. Application No. 62040516; and (c) entitled "Split-lip Shear Shape Washer Nozzle," filed May 1, 2015, No. US application 62155693. technical field [0003] The present invention relates to car washer nozzles for cleaning relatively small external surfaces such as external camera lens surfaces and cleaning them very well without the need for mechanical wipers or the like. Background technique [0004] The spraying performance of fluid type washer nozzles for high efficiency (large coverage, high velocity and low flow rate) is well known. However, a major limitation of fluid nozz...
