GAS VALVE WITH OVERTRAVEL
First Claim
Patent Images
1. A gas valve comprising:
- a valve body;
a valve member disposed within the valve body, the valve member movable between an open position in which gas flow is permitted through the gas valve and a closed position in which gas flow is not permitted through the gas valve; and
a resilient sealing ring disposed between the valve member and the valve body, the resilient sealing ring being adapted to permit the valve member to continue moving beyond a position in which the valve member initially reaches its closed position.

Abstract
A gas valve may include a valve body and a valve member disposed within the valve body. A resilient sealing ring may be disposed within the valve body such that the valve member achieves a closed position when the valve member contacts the resilient sealing ring. In some instances, a gas valve may include both an upper resilient sealing ring and a lower resilient sealing ring. The upper resilient sealing ring and the lower resilient sealing ring may both permit overtravel.

9. A gas valve comprising:
-
a valve body;
a valve member disposed within the valve body, the valve member comprising a first disk and a second disk, the valve member having an open position and a closed position;
a first resilient sealing ring disposed within the valve body proximate the first disk; and
a second resilient sealing ring secured to the valve member proximate the second disk;
wherein when the valve member is in its closed position, the first disk contacts the first resilient sealing ring and the second resilient sealing ring contacts the valve body. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
