Abstract:
An integrally formed, one-piece construction nozzle body having a primary flow channel and associated secondary flow channel and outlet configuration which cooperate to produce a jet of fluid having a predetermined geometric configuration. A system and method are also shown for creating the one-piece construction nozzle body.

A water-spraying positioning device of a windshield comprises a sleeve; a rear inner wall of the sleeve being threaded; a front end of the sleeve having a light transmitting hole; a laser indicator being installed within the sleeve; a front end of the laser indicator being installed with a light projection seat; laser beams from the light projection seat transmitting through the light transmitting hole; and the thread of the sleeve being screwed with an adjusting rod; an outer thread of the adjusting rod serving to screw to the rear end of the sleeve; a center portion at an rear end surface of the adjusting rod being axially protruded with an ejecting rod; and a center portion of the rear end surface of the ejecting rod being axially protruded with an axial rod; and the axial rod being coaxial with the laser beam.
Abstract:
Disclosed is a device for cleaning a window of a motor vehicle, comprising a cleaning nozzle (9) that is mounted in a nozzle holder (4) so as to be pivotable about a horizontal axis. The nozzle holder (4) is fastened in a fixed manner to a body sheet of the motor vehicle. A specific spraying range which is to be sprinkled with cleaning liquid can be adjusted on the window when the cleaning nozzle (9) is pivoted.
Abstract:
In a cleaning device for a vehicle lamp for jetting a cleaning liquid to a front surface of a vehicle lamp by a piston and a cylinder, the piston is urged in the direction in which it is retracted into the cylinder by a tensile spring arranged between the piston and the cylinder and passing through the inside of the piston.
Abstract:
The invention comprises a curved fluidic device and a housing piece with a curved slot to accommodate the curved fluidic device. The aim angle can be varied greatly by changing the depth of insertion of the fluidic device into the curved slot. By adjusting the curvature of the fluidic device and slot, the amount of variation possible and sensitivity to insertion depth can be controlled. With more curvature, the aim angle can be adjusted more but is more sensitive to insertion depth tolerance. With less curvature, the insertion depth is more robust but the aim adjustment range is smaller.
Abstract:
The device is comprised of a jet body (2) and a body for a fan shaped squirt (3) which can be mutually coupled. The squirt body (3) has a squirting orifice (9) which comprises four consecutively connected portions, of which, in the washer fluid flow direction, the first portion (10) is conical and in decreasing section; the second section portion (11) forms a spherical cap in decreasing section; the third portion (12) is in rectangular cross-section and in increasing section; and the fourth portion (15) is in rectangular cross-section in decreasing section in said flow direction and configures a convex outlet edge (16), which is surrounded by an outer lateral squirting groove.
Abstract:
A nozzle tip of the washer nozzle has a configuration of a “fluidics type nozzle”. A diffusion angle β (jet angle in a width direction) of diffusive flow diffusively jetted from a diffusive jet port is determined by a ratio E of a cross-sectional area of a liquid inlet port and a cross-sectional area of the diffusive jet port. The diffusion angle β of the diffusive flow is set larger than a predetermined angle W formed by a pair of jet port sidewalls. That is, the diffusive flow jetted from the diffusive jet port at the diffusion angle β, which is determined by the cross-sectional area ratio E, is restricted its diffusion (diffusive limit) by the pair of jet port sidewalls (angle W) disposed downstream of the diffusive jet port.
Abstract:
The invention relates to a nozzle and a washing system in particular for vehicle windscreens, comprising a nozzle body with a receiving device provided in the nozzle body, into which receiving device a nozzle insert is or can be inserted, wherein the nozzle insert influences the jet form of a liquid jet leaving the nozzle. The invention is characterized in that the receiving device has at least two inlets for the cleaning liquid and in that the nozzle insert is designed such that it influences the cleaning liquid coming from one inlet in a different manner from the cleaning liquid coming from another inlet.
Abstract:
A fluid-dispensing nozzle assembly automatically pivotally adjusts within a defined range of motion, to consistently project a fluid toward a windshield for contact at a designated area thereof, regardless of the velocity of ambient air therepast. The nozzle assembly adjusts automatically without requiring electric motors or other energy input. The pivotally adjustable fluid-dispensing nozzle assembly includes a support member and a nozzle member which is pivotally attached to the support member. The nozzle member is provided with an air engaging surface, to enable air moving therepast to pivotally move the nozzle member, once the passing air achieves a predetermined flow rate.
Abstract:
An orifice holding spring disk. The spring disk is utilized to retain orifice(s) against a smooth flat platen surface. The spring disk may further comprise an inlet flow conditioning nozzle, provided in (a) a flow collimating configuration to produce a coherent flow waterjet, or (b) in a de-collimating configuration to produce a divergent waterjet. The spring disk has an annular outer ring, one or more through-holes, and counterbores to form wells in the spring disk. The wells are slightly larger in diameter than the particular orifice to be mounted and slightly shallower (in the water flow direction) than the thickness of the orifice. A nozzle cap compresses the platen and spring disc against a high pressure inlet tube. The outer diameter of the spring disk is forced to flex to the cap surface while the center portion is restrained by the orifice that is resting on the platen.
