Directional control valve — Directional control valves are one of the most fundamental parts in hydraulic machinery. They allow fluid flow into different paths from one or more sources. They usually consist of a piston inside a cylinder which is mechanically or electrically … Wikipedia
ratchet valve — A valve normally used in the wing flap system to retain pressure in the flap actuating cylinder, thereby preventing the flaps from drooping while they are up when the airplane is on the ground and from creeping while they are down when the… … Aviation dictionary
Continuous 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… … Wikipedia
blow-back valve — The valve in the flap system that prevents the flaps from being lowered at too high an air speed. If the flaps are down and the air speed increases to too high a value, the flaps will retract automatically. Also called a flap overload valve. Blow … Aviation dictionary
flap-overload valve — A valve in the flap system that prevents the flaps from being lowered at speeds that may cause structural damage. If the pilot tries to lower the flaps at higher than permissible speeds, causing excessive air loads on the flap, the valve acts to… … Aviation dictionary
Poppet 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… … Wikipedia
Double beat valve — The double beat valve, drop valve or equilibrium valve is a type of poppet valve arranged to allow it to be opened against a high pressure with a minimum of force. One of its uses is in steam engines to admit steam to the cylinders and to release … Wikipedia
solenoid selector valve — A selector valve operated by a solenoid. This type of selector valve is used when it is desired either to locate the valves close to the actuating cylinders or avoid plumbing that is necessary if the valves are located in the pilot’s compartment… … Aviation dictionary
cross-flow valve — A valve meant to bypass hydraulic fluid from the landing gear upline to the downline when the landing gear is being extended. The weight of the landing gear, when it is released, is so great that it falls very rapidly. Under these conditions,… … Aviation dictionary
open-center selector valve — A type of hydraulic selector valve used in an open center hydraulic system that allows hydraulic fluid to flow from the pump to the reservoir when the selector valve is placed in neutral (i.e., when none of the actuating cylinders are receiving… … Aviation dictionary
shuttle valve — A valve in which the actuating member shuttles back and forth diverting pressure from one channel to another … Dictionary of automotive terms
