Assembly resonant frequencies are additionally or alternatively altered through choice of viscoelastic elements and inclusions (e.g., shear-thickening materials) in the reservoir and/or peripheral groove. Peripheral groove fenestrations increase valve assembly responsiveness to longitudinal compressive force while stabilizing peripheral groove elements. | 11-07-2013 |

| 20110265900 | INFLATING VALVE FOR AN INFLATABLE OBJECT - An inflating valve for an inflatable object has a body, a valve disk, a cap and a recoil member. The body is body and has a passage and a disk mount. The passage is defined through the body and has a bottom opening. The valve disk is attached securely to the bottom of the body to close the bottom opening of the passage and has a mounting end and a free end. The mounting end is mounted securely on the disk mount of the body. The free end is opposite to the mounting end. The cap is attached to the body around the bottom opening and holds the valve disk inside. The recoil member is mounted between the valve disk and the cap to push the valve disk closing the bottom opening of the passage in the body. | 11-03-2011 |

| 20080308166 | Connector/Device with Reflux Valves - The present invention provides a device which includes reflux valves in combination with components such that a fluid flow occurs when connections are made and stops when disconnected. | 12-18-2008 |
| 20130008542 | DIAPHRAGM VALVE AND METHODS AND ACCESSORIES THEREFOR - Various diaphragm valves and accessories therefore are disclosed herein which improve on existing diaphragm valves and accessories and overcome many of the shortcomings of same. Related methods to these valves and accessories and/or their manufacture, assembly or use are also disclosed. | 01-10-2013 |
| 20140166140 | MEMS Check Valve - A MEMS check valve includes a supporting portion having a first perforation therethrough sized to permit fluid flow and includes a displaceable portion having a second perforation therethrough sized to permit fluid flow. The displaceable portion may be moveable relative to the supporting portion between a closed position inhibiting fluid flow through the valve and an open position permitting fluid flow through the valve. The first and second perforations are offset to inhibit fluid flow when the displaceable portion is in the first position, and fluid may flow through the first and second perforations when the displaceable portion is in the second position. | 06-19-2014 |
| 20140290778 | FLUID CONTROL VALVE - In order to make it possible to increase a diameter and output thereof, a diaphragm structure is provided that has low repulsiveness, can be largely deformed to increase a stroke even without being applied with a large force from an actuator, and is unlikely to give rise to a defect or fault even when formed thin, and a fluid control valve is provided with the diaphragm structure and the actuator that presses the diaphragm structure, wherein the diaphragm structure is provided with: a protruding part that is formed in a tubular shape and pressed by the actuator; a brim part that spreads from a base end of the protruding part outward with respect to the protruding part; and a support part that is formed on an outer circumference of the brim part and attached to another member, and the brim part is formed in a film shape. | 10-02-2014 |
