Washer fluid vehicle reservoir
Disclosed is an improved vehicle reservoir system for managing the distribution of applicable fluids, including either liquids or gases individually, simultaneously, or a combination of these in a predefined sequence. In one embodiment, a first reservoir contains a non-pressurized fluid that is transferred to a distribution manifold and a second reservoir contains a pressurized fluid that can be transferred to the distribution fluid for admixing with the first reservoir fluid, or to a second distribution manifold, or a combination thereof.
1. A washer reservoir system for a vehicle comprising:
a first reservoir for receipt of a liquid;
a pump coupled to an outlet of said first reservoir;
a second reservoir for receipt of compressed gas;
a reservoir solenoid coupled to an outlet of said second reservoir;
a manifold having an inlet fluidly coupled to said pump and an inlet fluidly coupled to said reservoir solenoid, said manifold having a plurality of manifold outlets, said manifold constructed and arranged to distribute to said manifold outlets a first sequence of liquid transferred through said pump, a second sequence of liquid transferred through said pump and compressed gas passed through said reservoir solenoid, and a third sequence of compressed gas passed through said reservoir solenoid; said manifold comprises a first manifold having at least one first outlet and at least one second outlet, a second manifold having at least one first outlet and at least one second outlet, the first reservoir connected to the first manifold and the second reservoir connected to the second manifold, wherein the first sequence distributes liquid from the at least one first outlet of the first manifold, the second sequence distributes the liquid and compressed gas through the at least one second outlet of the first manifold and the at least one second outlet of the second manifold to a joined outlet, and the third sequence distributes compressed gas through the at least one first outlet of the second manifold; and
a plurality of manifold solenoids fluidly coupled to each of the at least one first and second outlets of the first and second manifolds to manage distribution of each sequence of liquid and compressed gas;
wherein operation of said reservoir solenoid and said pump allows selection of said first, second and third sequence with said manifold solenoids constructed and arranged to distribute a selected sequence.
2. The washer reservoir system according to claim 1 wherein said manifold outlets are sized to limit the flow of fluid through each said outlet.
3. The washer reservoir system according to claim 2 wherein at least one said manifold outlet has a different diameter than an adjoining manifold outlet.
4. The washer reservoir system according to claim 1 wherein at least one manifold outlet is bell shaped.
5. The washer reservoir system according to claim 1 wherein said manifold is metered for providing a pulse of liquid, followed by a pulse of compressed gas, and a pulse of fluid.
6. The washer reservoir system according to claim 1 including a check valve positioned after said pump wherein said check valve prevents backflow of liquid into said first reservoir.
7. The washer reservoir system according to claim 1 including a bladder placed within said manifold, said bladder constructed and arranged to maintain a predetermined fluid pressure within said manifold.
8. The washer reservoir system according to claim 1 wherein said manifold is formed integral with said first reservoir.
9. The washer reservoir system according to claim 1 wherein said manifold is formed integrally with said second reservoir.
