Magnetically actuated shut-off valve
View Patent ↗A magnetic actuator assembly is disclosed, and includes a core, wiring, and a gate assembly. The core is constructed of a magnetic material, and includes a first end and a second end. The wiring is wound around a portion of the core. A predetermined amount of electric current is applied to the wiring to induce a magnetic field within the core. The gate assembly is positioned between the first end and a second end of the core. The gate assembly comprises a first gate member traveling between the first end and a second end of the core based on a threshold force being applied to the gate assembly. The threshold force is created by the magnetic field.
1. A magnetic actuator assembly, comprising:
a core constructed of a magnetic material, the core including a first end and a second end;
wiring wound around a portion of the core, wherein a predetermined amount of electric current is applied to the wiring to induce a magnetic field within the core; and
a gate assembly positioned between the first end and a second end of the core, the gate assembly comprising:
a first gate member traveling between the first end and the second end of the core based on a threshold force being applied to the gate assembly, wherein the threshold force is created by the magnetic field; and
a biasing element located between the second end of the core and a lower surface of the gate assembly, the biasing element biasing the gate assembly towards the first end of the core.
2. The magnetic actuator assembly of claim 1 , wherein the threshold force is sufficient to unseat the gate assembly from a starting position, and causes the gate assembly to move into a second position.
3. The magnetic actuator assembly of claim 1 , wherein the first gate member is constructed of magnetized material.
4. The magnetic actuator assembly of claim 1 , wherein a permanent magnet is attached to both an upper surface and a lower surface of the first gate member.
5. The magnetic actuator assembly of claim 1 , wherein the gate assembly comprises a second gate member, wherein both the first gate member and the second gate member travel between the first surface and the second surface together.
6. The magnetic actuator assembly of claim 5 , wherein the gate assembly comprises an elastic member received between the first gate member and the second gate member.
7. The magnetic actuator assembly of claim 1 , comprising a bobbin surrounding a portion of the core, wherein the wiring is wound around the bobbin.
8. The magnetic actuator assembly of claim 1 , wherein the core is constructed of two symmetrical half sections.
9. The magnetic actuator assembly of claim 8 , wherein the two symmetrical half sections are constructed of a series of sheets that act as a conduit for magnetic flux to travel.
10. A housing, comprising:
a first section having a first conduit portion;
a second section having a second conduit portion that is in fluid communication with the first conduit portion, wherein the first section and the second section are joined together to define the housing; and
a magnetic actuator assembly located within the housing, comprising:
a core constructed of a magnetic material, the core including a first end and a second end;
a bobbin surrounding a portion of the core;
wiring wound around the bobbin, wherein a predetermined amount of electric current is applied to the wiring to induce a magnetic field within the core; and
a gate assembly positioned between the first end and the second end of the core, the gate assembly defining a passageway that blocks a flow of fluid flowing from the first conduit portion if the gate assembly is in a closed position, the gate assembly comprising:
a first gate member defining a first aperture;
a second gate member defining a second aperture; and
an elastic member received between the first gate member and the second gate member, the elastic member defining an elastic member aperture, wherein the first aperture of the first gate assembly, the second aperture of the second gate assembly, and the elastic member aperture of the elastic member are aligned with one another and define the passageway of the gate assembly, and wherein both the first gate member and the second gate member travel together between the first end and the second end of the core based on a threshold force being applied to the gate assembly, wherein the threshold force is created by the magnetic field.
11. The housing of claim 10 , wherein the threshold force is sufficient to unseat the gate assembly from the closed position, and causes the gate assembly to move into an open position.
12. The housing of claim 10 , wherein the first gate member and the second gate member are both constructed of magnetized material.
13. The housing of claim 10 , wherein a permanent magnets are attached to an upper surface and a lower surface of both the first gate member and the second gate member.
14. The housing of claim 10 , wherein the core is constructed of two symmetrical half sections.
15. The housing of claim 14 , wherein the two symmetrical half sections are constructed of a series of sheets that act as a conduit for magnetic flux to travel.
16. The housing of claim 10 , wherein the first section and the second section of the housing are plastic injection molded components.
17. The housing of claim 10 , wherein the first section and the second section of the housing are joined together by a plastic weld.
18. The housing of claim 10 , wherein the magnetic actuator assembly comprises a biasing element to bias the gate assembly in the closed position.
