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 lead — The number of degrees of the crankshaft before the top or bottom center, at which the intake or exhaust valves open or close. For example, if the intake valve opens when the crankshaft is 25° before the piston reaches the top of the exhaust… …
3valve — 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 …
4Valve job — A valve job is an operation which is performed on any four stroke cycle, internal combustion engine, the purpose of which is to clean up the mating surfaces of the poppet valves that control the intake and exhaust of the air/fuel mixture that… …
5valve lag — The number of degrees of crankshaft rotation after a piston passes the top or bottom center of its stroke, at which the intake or exhaust valves open or close. For example, if the exhaust valve closes at 60° of crankshaft rotation after the… …
6valve overlap — The portion of the operating cycle of a reciprocating engine in which, when the piston is passing TDC (top dead center) on the exhaust stroke, both the intake and exhaust valves are open. Valve overlap increases the efficiency of the engine… …
7valve ports — The openings in the cylinder heads of a reciprocating engine through which the fuel air mixture flows into the cylinder and burned gases leave …
8Sleeve valve — The sleeve valve is a type of valve mechanism for piston engines, distinct from the more common poppet valve. They saw use in some pre World War II luxury cars, sports cars, the Willys Knight car and light truck, and saw substantial use in… …
92-stroke power valve system — The 2 stroke power valve system is an improvement to a conventional two stroke engine that gives a high power output over a wider RPM range. Operation of a two stroke engine A stroke is the action of a piston travelling the full length of its… …
10Reed valve — Reed valves restrict flow of gases to a single direction and consist of thin flexible metal or fiberglass strips fixed on one end that open and close upon changing pressures across opposite sides of the valve. They operate in a similar manner to… …
