Cleaning systems specially adapted for land vehicles comprised of liquid and air spray nozzles, a tube, and a control unit for controlling the distribution of fluid and air for cleaning exterior cameras and sensors on land vehicles
Provided is a PCV valve assembly that includes a fluidic geometry that allows for the flow of combustion fluid/gas to flow between an inlet and an outlet and switch between two modes of operation, (i) a radial or high flow mode, and (ii) a tangential or low flow mode, as dictated during the operation of the engine. At low vacuums, the fluidic equipped PCV valve assembly has been tuned to operate in the radial mode producing high flow rates due to low flow resistance. As vacuum increases, the PCV valve assembly is tuned to automatically switch modes. This may be enabled due to the shape of the fluidic geometry and the bypass channel which is adapted to vary the amount of flow between a first and a second control ports. The bypass channel allows the geometric fluidic pattern to switch between the high flow mode and the low flow mode.

A low flow compact spray head design for cleaning applications, especially for camera lens wash includes a miniature spray nozzle head (200) which is about 5 mm in diameter or less for a single direction spray nozzle and about 8 mm in diameter of less for a nozzle with multiple sprays. The washer fluid is fed from the bottom of nozzle along a flow axis and is separated into two flows via two power nozzles (220a, 220b) or inlets which turn the flows 90° to become opposing jets impinging upon each other inside an interaction region (230). Uniform stream lines are generated by the two direct facing jets and converge at the nozzle throat to become a uniform spray fan, which is on a plane perpendicular to the axis of cylindrical nozzle head (200). This fluidic circuit design enables a miniature size low flowrate nozzle to operate well consistently with low flow rate (e.g., a flow rate of about 150 mL/min to about 300 mL/min at 25 psi, or even a flow rate of about 250 mL/min at 25 psi or above, at a viscosity of about 25 CP) at cold temperate (-4°F or lower) with 50 percent ethanol.

Provided is a PCV valve assembly that includes a fluidic geometry that allows for the flow of combustion fluid/gas to flow between an inlet and an outlet and switch between two modes of operation, (i) a radial or high flow mode, and (ii) a tangential or low flow mode, as dictated during the operation of the engine. At low vacuums, the fluidic equipped PCV valve assembly has been tuned to operate in the radial mode producing high flow rates due to low flow resistance. As vacuum increases, the PCV valve assembly is tuned to automatically switch modes. This may be enabled due to the shape of the fluidic geometry and the bypass channel which is adapted to vary the amount of flow between a first and a second control ports. The bypass channel allows the geometric fluidic pattern to switch between the high flow mode and the low flow mode.
Provided is a bi-directional PCV valve assembly, system and method. The bi-directional PCV valve may include a fluidic geometry that allows for a flow of fluid a high flow rate in one direction, forward flow, and a low flow rate in the opposite direction, reverse flow. The reverse flow includes a swirling flow that increases the pressure drop and reduces the flow rate to a third of the flow rate of the forward flow. The disclosed assembly produces a strong swirling flow (vortex) in the reverse direction and an efficient (low pressure drop) flow in the forward direction.

The power nozzle channels generate opposing offset flows which are aimed to very efficiently generate a vortex of fluid which projects distally from the exit aperture as a swirled spray of small droplets 152 having a rapid angular velocity.

An improved automotive pump assembly includes a volute pumping chamber configured to operably contain a rotatable impeller which, when driven, draws fluid into a fluid inlet and pumps the fluid to and through a fluid outlet. The volute chamber has an exterior sidewall with a constant internal first radius over a first sidewall portion and transitions to a second sidewall portion of increasing radius. The chamber's second sidewall portion defines a first end at a sidewall transition point tangent to the constant radius sidewall segment to define a second end which is tangent to the volute chamber's fluid outlet with a second radius that is greater than the first radius.
A fluid spraying or nozzle system adapted for use with cold fluids, viscous fluids or fluids under light pressure includes a fluidic oscillator having a power nozzle and an oscillation chamber coupled to the power nozzle for issuing a jet of fluid into the oscillation chamber and an outlet aperture spraying a jet of fluid into ambient space. The oscillator's walls define an oscillation inducing interaction region causing the jet of fluid to rhythmically sweep back and forth between the sidewalls in the oscillation chamber. The oscillation inducing interaction region defines an outlet throat width which is adapted to work with the power nozzle's width and an a bell-shaped feed that spreads the fluid jet as it leaves the power nozzle, so that the interaction region and feedback channels are quickly filled with fluid at a low pressure and the fluidic oscillator is activated to generate a desired fan pattern of fluid spray.

An enhanced pump assembly includes an impeller and volute casing designed to provide high operating pressures (“P”) and flow rates (“Q”) with low energy usage. The impeller has a central shaft carrying radially projecting curved primary vanes, and each primary vane also has a twist in the radial direction. Secondary impeller vanes define triangular connecting fillet-like wall segments connecting each primary vane to the impeller shaft. The casing of the pump has a slight spiral deviation so that the pump chamber's radial sidewall flares away from the swept area of the impeller's vanes to define a fluid outlet that contributes to higher P-Q performance, especially when pumping colder fluids.
