Abstract: The disclosure relates to various fluid nozzles possessing the ability to produce a keystone-shaped spray pattern. In one embodiment, the present disclosure relates to one or more fluid nozzles that are able to produce a keystone-shaped spray pattern. In another embodiment, the present disclosure relates to two or more fluid nozzles that are able to be stitched together to produce a keystone-shaped spray pattern. In still another embodiment, the fluid nozzle, or nozzles, of the present disclosure are able to produce a desired spray pattern at low flow rates.

Abstract: A miniature low-flow, fluid conserving washer nozzle has an elongated housing enclosing an interior volume aligned along an inlet axis which receives an elongated insert member with internal fluid passages defining first and second power nozzles, so that accelerating first and second fluid flows are aimed by the first and second power nozzles toward one another in an interaction region defined within the insert with an insert throat to aim spray laterally or transversely along a spray axis through an aligned sidewall aperture in the nozzle housing. The nozzle may generate a planar oscillating sweeping fan of spray, produced by fluidic oscillations at low flow rates, typically 150-300 ml/min at 25 psi. The fan of spray generated may be varied from 20° to 70° or about 15°-60°. The outer dimensions of spray head could be as small as 3.5 mm. The fluidic geometry is also capable of spraying high viscosity liquids up to 25 CP or up to 15 CP.

Abstract: A micro-sized structure and construction method for a fluidic oscillator wash or spray nozzle (100 or 250) has a nozzle housing (110 or 252) enclosing an interior cavity (112 or 262) which receives an insert (114 or 254) having internal fluid passages defining first and second power nozzles (120, 122 or 280, 282). The power nozzles receive pressurized fluid (130) flowing through the interior cavity of the housing, where the fluid flows into the cavity at the bottom of the housing and flows upwardly to inlets (140, 142) for the power nozzles so that accelerating first and second fluid flows are aimed by the power nozzles toward one another in an interaction region (154 or 284) which exhausts laterally along a spray axis through a horn-shaped throat defined partly within the insert and partly within the flared spray outlet orifice (160 or 290) defined through the sidewall (162) in the housing.

Abstract: A vehicle sensor cleaning system that includes one or more vehicle sensors and a cleaning device. The system determines parameters for a cleaning event based on sensed information, operating parameters of the vehicle, or environmental information. The system cleans the one or more sensors to allow for safe operation of the vehicle.

Abstract: A pop-up external lens washing system has an extendable aiming fixture configured to aim a lens cleaning spray at an external lens which is exposed to the elements and apt to become soiled with debris. The extendable nozzle assembly is configured to be aimed toward the external lens by the extended aiming fixture during the washing operation only and has at least one laterally offset washing nozzle projecting from the aiming fixture to a spray washing fluid toward the external lens surface, spraying at a shallow, glancing spray aiming angle to impinge upon and wash the lens external surface.

Abstract: A vehicle sensor cleaning system that includes one or more vehicle sensors and a cleaning device. The system may further include an area to accommodate expansion of fluids due to freezing, such as a spring-loaded expansion valve, a floating barb expansion valve, or a three-way valve to a standpipe. The system may include systems and methods to evacuate the manifold such as purging with compressed or ambient air, or a syringe or drain valve mechanism. The system may be heated by a heating device such as a PTC heater, a resistive wire, or a low current coil. The system may provide a track or line to recirculate the fluid. These systems and methods may be incorporated into any portion of the system and in any combination. The systems and methods may be actuated by a mechanical or electrical switch that turns on based on direct pressure as a result of expanding or freezing fluid, in response to input by a temperature, pressure, or other sensor, or in response to automated or user input. The manifold may also comprise various modules and connections to adapt the system to any vehicle as desired.
