Cylinder (engine)

Cylinder is a term used in the art, particularly in the engineering term for various machine elements or assemblies. A common feature is often carried out at least approximately in the form of a (circular ) cylinder as a hollow cylinder the design.

Use of the term cylinder

Generally

  • A rotating part of the machine, is exerted by the pressure on a workpiece, or the workpiece by giving the direction changing properties (e.g., in the calender, or the rotary cylinder of a printing machine ), also referred to as a roller.
  • The operating element of a technical circuit, an actuator (often a valve ) which is controlled.

For motors or pumps

  • The tubular chamber in which a piston moves, as used in piston pumps, steam engines and internal combustion piston engines. Such machines are called piston engines. Piston machines can have one or more cylinders. The stroke ( the linear movement ) of the piston in the cylinder of the piston engine may be by means of a connecting rod into a rotating movement, for example a wheel or a crank shaft to be converted. The converse, i.e., converting a rotation into a translational movement is possible. In combustion engines, the cylinder on one side opens into the crankcase on the other side it is closed or closable by means of valves.

In the linear technology

  • Electromechanical cylinder, also referred to as an electro- mechanical lifting cylinders or electromechanical actuators. The basic principle of electro-mechanical lift cylinder is also found in so-called Teleskophubsäulen (also: mast or telescopic drive ) again.

And gas springs have a cylinder which is filled with gas, which causes its pressure by the extension ( the advance stroke ) of the gas cylinder piston.

In the Fluidics

  • A drive unit for linear - less frequently rotating - movement. The movement of the piston is transmitted via the piston rod, or magnetic adhesion to the parts to be moved. The lead-out of the piston rod from the pressure chamber must be sealed. A distinction must be single-acting and double-acting cylinder ( work is performed in only one direction or in both directions). Cylinder in the hydraulic or pneumatic are the two fluid elements Pneumatic cylinder and
  • Hydraulic cylinder

Circuit symbols for cylinders for use in pneumatic or hydraulic circuit diagrams can be found in the list of character ( fluid power ).

In the printing industry

  • A printing cylinder
  • Cylinder pressure techniques are: cylinder to cylinder, cylinder against surface
