Valve System
First Claim
1. A valve having an open position and a closed position comprising:
- a. an orifice closing member adjacent to an orifice through which fluid can flow;
b. a displacement member having a first portion and a second portion, wherein said first portion is adjacent to the orifice closing member when the valve is in said open position;
c. a first magnet and a second magnet wherein said first and second magnets are sufficiently proximate to said displacement member to exert a magnetic force on said displacement member; and
d. an actuator for generating a magnetic field to move said displacement member toward said first magnet, cause said first portion to press against the orifice closing member, and cause the orifice closing member to close said orifice.

Abstract
The present invention is directed to a valve that has an orifice closing member adjacent to an orifice through which fluid can flow, a displacement member having a first portion and a second portion, where the first portion is adjacent to the orifice closing member when the valve is in an open position, a first magnet and a second magnet where the first and second magnets are sufficiently proximate to the displacement member to exert a magnetic force on the displacement member, and an actuator for generating a magnetic field to move the displacement member toward the first magnet, cause the first portion to press against the orifice closing member, and cause the orifice closing member to close the orifice.

12. A valve comprising:
-
a. an orifice closing member adjacent to an orifice through which fluid can flow wherein said orifice closing member compresses against a valve seat when the valve is in a closed position; b. a moveable member that is physically movable relative to said orifice closing member wherein said moveable member moves from a first position when said valve is in an open position to a second position when said valve is in said closed position and wherein, in said second position, the moveable member presses against the orifice closing member to cause said orifice closing member to compress against the valve seat; c. a first magnet and a second magnet having a separation wherein said first magnet and second magnet generate a magnetic field in the separation and wherein said magnetic field has a direction; and d. an actuator capable of generating an electromagnetic force, wherein said electromagnetic force reverses the direction of said magnetic field. - View Dependent Claims (13, 14, 15, 16)

- 18. A kidney dialysis system comprising a valve having a first stable state and a second stable state wherein said valve comprises magnets, wherein an input of energy into said valve creates magnetic forces which cause a displacement member to move within said kidney dialysis system, wherein the movement of said displacement member causes a change between the first state and the second state, and wherein maintenance of said first or second state does not require energy input.
