Estimating the term…
The present invention relates to a system for spraying cleaning fluid. The system includes a first spray nozzle and a second spray nozzle, each capable of receiving cleaning fluid and spraying it. The system also includes a directional valve with an inlet, a first outlet and a second outlet. The directional valve being capable of conveying cleaning fluid from the inlet to the first outlet when cleaning fluid received at the inlet has a pressure below a given threshold, and which is capable of conveying cleaning fluid from the inlet to the second outlet when the cleaning fluid received at the inlet has a pressure above the given threshold. The system further includes a pump capable of injecting fluid into the directional valve and capable of varying the pressure of the fluid.
A cleaning fluid spraying system comprising:
An assembly comprising a spraying system, the spraying system including a first spray nozzle and a second spray nozzle, each capable of receiving cleaning fluid and of spraying the cleaning fluid out of the spraying system, a directional valve including an inlet, a first outlet and a second outlet, the directional valve being capable of directing cleaning fluid from the inlet to the first outlet when cleaning fluid received at the inlet has a pressure below a given threshold, and capable of directing cleaning fluid from the inlet to the second outlet when cleaning fluid received at the inlet has a pressure above the given threshold, and at least a first protective surface of a sensor and a second protective surface of a sensor, the first nozzle being configured to spray fluid onto the first protective surface and the second nozzle being configured to spray fluid onto the second protective surface.
