Abstract

A valve assembly comprises a sealed container connected to a hot water supply line and a cold water supply line. The sealed container has an outlet for supplying at least one of hot water or cold water to a faucet. A valve mechanism is located inside the sealed container comprising a stationary mixing part and a moveable mixing part. A magnetic coupling adapter has a first magnetic structure located outside of a wall of the sealed container. A first magnetic structure is made of a first magnetizable material having a first plurality of first printed maxels having a first polarity pattern. A second magnetic structure located inside the wall of the sealed container is made of a second magnetizable material having a second plurality of second printed maxels having a second polarity pattern that is complementary to the first polarity pattern. The first magnetic structure and second magnetic structure are magnetically coupled across the wall of the sealed container. A first adapter interface component located outside of the wall of the sealed container is associated with the first magnetic structure. A second adapter interface component located inside the wall of the sealed container is associated with the second magnetic structure and the moveable mixing part. A movement control mechanism includes a moveable handle associated with the first adapter interface, which is configured to control a movement of the magnetic coupling adapter and thereby a movement of the moveable mixing part to control flow and mixing of the hot and cold water.

Claims

1. A valve assembly, comprising:

a sealed container connected to a hot water supply line and a cold water supply line, said sealed container having an outlet for supplying at least one of a hot water or a cold water to a faucet;

a valve mechanism located side said sealed container, said valve mechanism comprising;

a stationary mixing part; and

a moveable mixing part;

a magnetic coupling adapter, comprising;

a first magnetic structure located outside of a wall of said seated container, said first magnetic structure being a first magnetizable material having a first plurality of first printed maxels having a first polarity pattern;

a second magnetic structure located inside said wall of said sealed container, said second magnetic structure being a second magnetizable material having a second plurality of second printed maxels having a second polarity pattern that is complementary to said first polarity pattern, said first magnetic structure and said second magnetic structure being magnetically coupled across said wall of said sealed container;

a first adapter interface component located outside of a wall of said sealed container and associated with said first magnetic structure; and

a second adapter interface component located inside said wall of said seated container and associated with said second magnetic structure and said moveable mixing part; and

a movement control mechanism including a moveable handle associated with said first adapter interface and configured to control a movement of said magnetic coupling adapter and thereby a movement of said moveable mixing part to control flow and mixing of said hot and said cold water.

2. The valve assembly of claim 1, wherein said stationary mixing part comprises a first side and a second side apposite said first side.

3. The valve assembly of claim 2, wherein said first side of said stationary mixing part comprises first inlet configured to receive said hot water from said hot water supply line, a second inlet configured to receive said cold water from said cold water supply line, and an outlet for supplying at least one of said hot water and said cold water to said faucet, said first and second inlets and said outlet extending from said first side of said stationary mixing part to said second side of said stationary mixing part.

4. The valve assembly of claim 3, wherein said moveable mixing part comprises a first side and a second side opposite said first side.

5. The valve assembly of claim 4, wherein said first side of said moveable mixing part comprises an outer portion, an inner portion, and a channel.

6. The valve assembly of claim 5, wherein said second side of said stationary mixing part and said first side of said movable mixing part are configured to interface with each other to provide a seal intended to prevent leakage of at least one of said cold water and said hot water out of said valve mechanism.

7. The valve assembly of claim 5, wherein a location of said inner portion of said first side of said moveable mixing part relative to the first and second inlets of said second side of said stationary mixing part controls said flow and said mixing of said hot water and said cold water.

8. The valve assembly of claim 1, wherein said moveable handle is configured for rotational movement.

9. The valve assembly of claim 1, wherein said moveable handle is configured for translational movement.

10. The valve assembly of claim 1, wherein said movement control mechanism further comprises:

a stem assembly attached to said handle and associated with said first adapter interface component.

11. The valve assembly of claim 10, where said stem assembly comprises a ball having a knuckle that can be placed into a recess of said first adapter interface component.

12. The valve assembly of claim 11, wherein said ball movable within a housing.

13. The valve assembly of claim 11, wherein movement of said ball is constrained.

14. The valve assembly of claim 1, wherein said movement of said moveable mixing part is a rotational movement.

15. The valve assembly of claim 1, wherein said movement of said moveable mixing part is a translational movement.

16. The valve assembly of claim 1, further comprising:

a puck associated with said stationary mixing part.

17. The valve assembly of claim 16, further comprising:

a gasket between said puck and said stationary mixing part.

18. The valve assembly of claim 1, further comprising:

a tap between at least one of the cold water supply line and the hot water supply line and the sealed container.

19. The valve assembly of claim 18, further comprising a piston connected to said tap.

20. The valve assembly of claim 1, where the sealed container is filled with grease.
