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 and wherein the first portion comprises a housing, elastic material, a rod and a gap between said elastic material and said rod;
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.

3. A valve having an open position and a closed osition 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 and wherein the first portion comprises a rod bonded to a cylinder and said second portion of said displacement member is a metal body with a diameter greater than said rod; 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.
