Cylinder most commonly refers to:
- Cylinder (geometry), a three-dimensional geometric figure
Cylinder may also refer to:
In its simplest form, a cylinder (from Greek κύλινδρος – kulindros, "roller, tumbler") is the surface formed by the points at a fixed distance from a given straight line called the axis of the cylinder. It is one of the most basic curvilinear geometric shapes.
A cylinder is the central working part of a reciprocating engine or pump, the space in which a piston travels. Multiple cylinders are commonly arranged side by side in a bank, or engine block, which is typically cast from aluminum or cast iron before receiving precision machine work. Cylinders may be sleeved (lined with a harder metal) or sleeveless (with a wear-resistant coating such as Nikasil). A sleeveless engine may also be referred to as a "patent-bore engine".
A cylinder's displacement, or swept volume, can be calculated by multiplying its cross-sectional area (the square of half the bore by pi) by the distance the piston travels within the cylinder (the stroke). The engine displacement can be calculated by multiplying the swept volume of one cylinder by the number of cylinders.
Presented symbolically,
$$\text{(Cylinder Volume)} = \pi \cdot \left(\frac{\text{bore}}{2}\right)^2 \cdot \text{Stroke}$$
(Engine Displacement) = (Cylinder Volume) ⋅ (Number of Cylinders)
A piston is seated inside each cylinder by several metal piston rings fitted around its outside surface in machined grooves; typically two for compressional sealing and one to seal the oil. The rings make near contact with the cylinder walls (sleeved or sleeveless), riding on a thin layer of lubricating oil; essential to keep the engine from seizing and necessitating a cylinder wall's durable surface.
During the earliest stage of an engine's life, its initial breaking-in or running-in period, small irregularities in the metals are encouraged to gradually form congruent grooves by avoiding extreme operating conditions. Later in its life, after mechanical wear has increased the spacing between the piston and the cylinder (with a consequent decrease in power output) the cylinders may be machined to a slightly larger diameter to receive new sleeves (where applicable) and piston rings, a process sometimes known as reboring.
The cylinders of a steam locomotive are the components that convert the power stored in the steam into motion.
Cylinders may be arranged in several different ways.
In firearms, the cylinder is the cylindrical, rotating part of a revolver containing multiple chambers. The cylinder revolves around a central axis in the revolver to bring each individual chamber into alignment with the barrel for firing. Each time the gun is cocked, the cylinder indexes by one chamber (in six-shooters, 60 °).
Cylinders typically hold six cartridges (hence revolvers sometimes being referred to as "six-shooters"), but some small frame revolvers only hold 5 cartridges, due to the smaller overall size of the gun and reduced space availability. The Nagant M1895 revolver has a 7 shot cylinder, the Webley-Fosbery Automatic Revolver has an 8-shot cylinder in .38 caliber, and the LeMat Revolver has a 9 shot cylinder. Several models of .22 rimfire caliber revolvers have cylinders holding 9 or 10 rounds.
As a general rule, cylinders are not designed to be detached from the firearm (except for cleaning). Rapid reloading is instead facilitated by the use of a speedloader or moon clip, although these only work on break-top and swing-out cylinder revolvers, for obvious reasons.
Cylinder is a subgenus of sea snails, marine gastropod mollusks n the genus Conus, in the family Conidae, the cone snails and their allies.
In the new classification of the family Conidae by Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015), Cylinder has become a subgenus of Conus: Conus (Cylinder) Petuch & Sargent, 2012 represented as Conus Thiele, 1929. The same study found Cylinder to be polyphyletic, but morphologically consistent, possibly corresponding to grades. Conus ammiralis, Conus canonicus and Conus dalli cluster with the type species Conus textile, the others form a separate clade.
