Filed:

Jan 5, 2001

Appl. No.:

09/754075

Inventors:

Dharapuram N. Srinath - Ellicott City MD
Eric Koehler - Woodstock MD

Assignee:

Bowles Fluidics Corporation - Columbia MD

International Classification:

B05B 108

US Classification:

2395891, 239101, 239462, 239590, 239600, 239DIG 3, 137833, 137835

Abstract:

A molded fluid device having a power nozzle with a width W and a coupling passage coupling a source of fluid to the power nozzle. The coupling passage is formed on one chip or insert surface and has a planar enlargement and a plurality of posts spaced across the enlargement, the spacing S between each post being less than the width of the power nozzle with the sum of spacing S being greater than the width W. A liquid spray nozzle is formed on an opposing chip surface and connected to the coupling passage downstream of the posts.

US Classification:

239589, 29428

Abstract:

A sprinkler assembly includes a sprinkler housing including at least one fluidic- circuit-receiving port carrying a fluidic insert configured to receive irrigation fluid and project the irrigation fluid in a desired spray pattern. The fluidic insert is held precisely in place by a retention ring adapted for insertion into the housing's interior lumen to provide a snap or friction fit within the housing while engaging and retaining the fluidic insert against impact forces from inrushing fluid surge. The retention ring fits entirely within the sprinkler assembly's housing or package, and is economically molded as a one-piece component, and does not have any effect on external appearance of the sprinkler assembly or any adverse effect on the fluidic insert's spray pattern.

Abstract:

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.

International Classification:

B60S 1/52
B60S 1/48

Abstract:

A vehicle speed, ambient temperature or surface-condition responsive wash system 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 having an impeller that is activated to supply fluid under pressure to a multi-mode nozzle assembly . 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 is initially operated in the second mode, or reverse direction, producing a lower pressure flow.
