A windshield washer system wherein a nozzle is mounted on the hood (H) of a vehicle and issues a jet of washer fluid in the ambient toward the windshield (W). The nozzle has a housing (E) and a projecting surface, air deflector or tab (T) formed with or attached to the nozzle housing (E) for aerodynamically assuring that the washer fluid impinges on the windshield (W) in a predetermined area thereon at speeds above a predetermined minimum. In preferred embodiments, the projecting surface, air deflector or tab (T) projects from about 6 mm to about 12 mm above the nozzle housing (E).

摘要:
In an automobile air flow system, air is forced through an air outlet element or nozzle (13, 21, 24) in a sweeping air stream pattern by an oscillating reed or vane member (42) supported solely at the downstream end (43) for air initiated oscillatory movement in the flow path of the air from the source; a weight (41) is on the free, upstream end of the vane and is of a size such that the rate of oscillation is determined by the spring constant of a spring in the vane member and the weight. The oscillating vane (42) is proportioned with respect to the cross-sectional size of the outlet such that at any extreme of its oscillatory movement it does not physically contact any other structural member.

An external lens washing system has an aiming fixture configured to support and constrain an external lens which is exposed to the elements and apt to become soiled with debris. A nozzle assembly is configured to be supported and aimed toward the external lens by the aiming fixture 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. Optionally, an integrated image sensor and lens washing assembly is configured for use with a remote control method for cleaning an exterior objective lens surface and includes a sealed image sensor housing assembly including an integral, remotely controllable lens cleaning system with an optimized configuration for aiming one or more cleansing sprays from one or more laterally offset fluidic oscillators.

A vehicle speed, ambient temperature or surface-condition responsive wash system 89 has a control system configured to adapt the wash system's operation to sensed operating conditions. The adaptive system and method selectively controlling aimed windshield washer fluid sprays comprises a multi (e.g., two) mode system with a washer fluid driving pump 80 having an impeller 121 that is activated to supply fluid under pressure to a multi-mode nozzle assembly 98. Selectable first, or low pressure, and second, or high pressure, modes are provided by controlling the pump's polarity and impeller spin direction, hi an exemplary embodiment, a two-mode pump 80 is initially operated in the second mode, or reverse direction, producing a lower pressure flow.
摘要:
A conformal, cup-shaped fluidic nozzle engineered to generate an oscillating spray is configured as a (e.g., 100, 400, 600 or 700). Preferably, the fluidic circuit's oscillation inducing geometry 710 is molded directly into the cup's interior wall surfaces and the one-piece fluidic cup may then fitted into an actuator (e.g., 340). The fluidic cup (e.g., 100, 400, 600 or 700) conforms to the actuator stem used in typical aerosol sprayers and trigger sprayers and so replaces the prior art “swirl cup” 70 that goes over the actuator stem (e.g., 320), With the fluidic cup (e.g., 100, 400, 600 or 700) and method of the present invention, vendors of liquid products and fluids sold in commercial aerosol sprayers 20 and trigger sprayers 800 can now provide very specifically tailored or customized sprays.
摘要:
A burner or torch system for mixing fuel with air includes a fluid oscillator for forming a jet or sheet of fuel and oscillating the jet in ambient air downstream of the fluid oscillator. This mixes air with fuel and achieves a combustible mixture a distance spaced from any physical structure of the burner or torch whereby a flame front of burning combustible mixture has a shape and distance from the fluid oscillator which is determined by the sweep angle, wave pattern and frequency of the fluid oscillator. Various forms of fluidic oscillators are disclosed.

Fluidic transducers of electrical signals from an electronic computer to accurately switch flow of a liquid to a utilization device. A liquid filled hollow channel (166 and 166') is accelerated along the flow axis thereof to produce a fluid control signal for a bistable fluidic switch element (112) with a cross-over type interaction channel (42) and a common outlet (45) to a pair of output passageways (147 and 148). In a preferred embodiment, electrical signals from an electronic computer (220) are supplied to a coil (170) centered by a spring (190 and 191) in a magnetic field, first in one direction of current flow and then in the opposite direction, to introduce bidirectional movement of the coil (170) and the hollow channel means (166 and 166') coupled thereto. The signals are preferably frequency modulated (205) (but may be pulse width modulated).
