1Valve — This article is about the flow control device. For the game developer, see Valve Corporation. For the electronic component, see Vacuum tube. For other uses, see Valve (disambiguation). These water valves are operated by handles. A valve is a… …
2valve — 1. A fold of the lining membrane of a canal or other hollow organ serving to retard or prevent a reflux of fluid. 2. Any formation or reduplication of tissue, or flaplike structure …
3Pressure-fed cycle (rocket) — The pressure fed cycle is a class of rocket engine designs. A separate gas supply, usually helium, pressurizes the propellant tanks to force fuel and oxidizer to the combustion chamber. To maintain adequate flow, the tank pressures must exceed… …
4Continuous variable valve timing — offers a unique ability to have independent control of the intake and exhaust valves in an internal combustion engine. For any engine load criteria, the timing of intake and exhaust can be independently programmed [1]. The main variations of… …

6Artificial heart valve — An artificial heart valve is a device implanted in the heart of a patient with heart valvular disease. When one of the four heart valves malfunctions, the medical choice may be to replace the natural valve with an artificial valve. This requires… …
7Angle seat piston valve — An angle seat piston valve is a pneumatically controlled valve with a piston actuator providing linear actuation to lift a seal off its seat. The seat is set at an angle to provide the maximum possible flow when unseated. Angle seat piston valves …
8Poppet valve — A poppet valve is a valve consisting of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem. The shaft guides the plug portion by sliding through a valve guide. In most… …
9Desmodromic valve — In general mechanical terms, the word desmodromic is used to refer to mechanisms that have different controls for their actuation in different directions. Desmodromic poppet valve in Ducati engine. A desmodromic valve is a reciprocating engine… …
10Variable valve timing — Variable valve timing, or VVT, is a generic term for an automobile piston engine technology. VVT allows the lift or duration or timing (some or all) of the intake or exhaust valves (or both) to be changed while the engine is in operation. Two… …
