Conical Seat Shut- Off Valve

A moveable valve for controlling flow of a pressurized working fluid was designed. This valve consists of a hollow, moveable floating piston pressed against a stationary solid seat, and can use the working fluid to seal the valve. This open/closed, novel valve is able to use metal-to-metal seats, without requiring...

When airline passengers travel in coach class, expectations are fairly low with regard to comfort. For example, most seats only offer two positions: straight for takeoff and landing, and a slight recline for the journey. Coach seats are relatively simple and lightweight structures compared to their more sophisticated counterparts in business class, first class, and super first class. Whereas a coach seat weighs approximately 100 pounds, seats in higher classes weigh 200 to 300 pounds each, depending on their features.
