Actuated elastomer valve
View Patent ↗The present disclosure provides an apparatus and method for actuating an elastomer valve. The apparatus includes a first solenoid at least partially surrounding a first moveable member. The apparatus also includes a second solenoid at least partially surrounding a second moveable member. The apparatus also includes an elastomer valve positioned between the first moveable member and the second moveable member. The first and second moveable members extend from the first and second solenoids to contact and open the elastomer valve when the first and second solenoids receive a first current. Further, the first and second moveable members retract towards the first and second solenoids to close the elastomer valve when the first and second solenoids receive a second current.
1. A balloon comprising:
an envelope; and
an apparatus coupled to the envelope, the apparatus comprising:
a first solenoid at least partially surrounding a first moveable member;
a second solenoid at least partially surrounding a second moveable member; and
an elastomer valve positioned between the first moveable member and the second moveable member, wherein the first and second moveable members extend from the first and second solenoids to contact and open the elastomer valve when the first and second solenoids receive a first current, and wherein the first and second moveable members retract towards the first and second solenoids to close the elastomer valve when the first and second solenoids receive a second current.
2. The balloon of claim 1 , wherein the first solenoid and the second solenoid are latching solenoids.
3. The balloon of claim 2 , wherein the first solenoid and the second solenoid include one or more magnets.
4. The balloon of claim 1 , wherein the elastomer valve is a four-way cuspid valve.
5. The balloon of claim 1 , wherein the elastomer valve is a duckbill valve.
6. The balloon of claim 1 , wherein the first current is reverse polarity, and wherein the second current is non-reversed polarity.
7. The balloon of claim 1 , wherein the apparatus further comprises:
a first spring between the first solenoid and the first moveable member; and
a second spring between the second solenoid and the second moveable member, wherein the first and second springs bias the first and second moveable members towards the elastomer valve.
8. A method comprising:
providing a balloon including an envelope;
providing a first solenoid at least partially surrounding a first moveable member;
providing a second solenoid at least partially surrounding a second moveable member;
providing an elastomer valve positioned between the first moveable member and the second moveable member, wherein the elastomer valve is coupled to the envelope;
providing a first current to the first and second solenoids, wherein the first current causes the first and second moveable members to extend from the first and second solenoids, and wherein the extended first and second moveable members contact and open the elastomer valve; and
providing a second current to the first and second solenoids, wherein the second current causes the first and second moveable members to retract towards the first and second solenoids, and wherein the retracted first and second moveable members cause the elastomer valve to close.
9. The method of claim 8 , wherein the first solenoid and the second solenoid are latching solenoids.
10. The method of claim 8 , wherein the elastomer valve is a four-way cuspid valve.
11. The method of claim 8 , wherein the elastomer valve is a duckbill valve.
12. The method of claim 8 , wherein the first current is reverse polarity.
13. The method of claim 8 , wherein the second current is non-reversed polarity.
14. The method of claim 8 , further comprising:
providing a first spring between the first solenoid and the first moveable member; and
providing a second spring between the second solenoid and the second moveable member, wherein the first and second springs bias the first and second moveable members towards the elastomer valve.
15. A balloon comprising:
an envelope;
a bladder positioned inside of the envelope; and
an altitude-control system, wherein the altitude-control system comprises:
a first solenoid at least partially surrounding a first moveable member;
a second solenoid at least partially surrounding a second moveable member; and
an elastomer valve positioned between the first moveable member and the second moveable member, wherein the first and second moveable members extend from the first and second solenoids to contact and open the elastomer valve when the first and second solenoids receive a first current, and wherein the first and second moveable members retract towards the first and second solenoids to close the elastomer valve when the first and second solenoids receive a second current.
16. The balloon of claim 15 , wherein the first solenoid and the second solenoid are latching solenoids.
17. The balloon of claim 15 , wherein the elastomer valve is a four-way cuspid valve.
18. The balloon of claim 15 , wherein the first current is reverse polarity, and wherein the second current is non-reversed polarity.
19. The balloon of claim 15 , wherein the altitude-control system further comprises:
a first spring between the first solenoid and the first moveable member; and
a second spring between the second solenoid and the second moveable member, wherein the first and second springs bias the first and second moveable members towards the elastomer valve.
