Qu'est-ce (qui) est T-slot piston - définition

MOVING COMPONENT OF RECIPROCATING ENGINES THAT IS CONTAINED BY A CYLINDER AND IS MADE GAS-TIGHT BY PISTON RINGS

Piston Linkage; Drawback of piston; Deflector piston; Trunk piston; Crosshead piston; Piston (technology)

Piston

·noun A sliding piece which either is moved by, or moves against, fluid pressure. It usually consists of a short cylinder fitting within a cylindrical vessel along which it moves, back and forth. It is used in steam engines to receive motion from the steam, and in pumps to transmit motion to a fluid; also for other purposes.

piston

['p?st(?)n]

¦ noun

1. a disc or short cylinder fitting closely within a tube in which it moves up and down against a liquid or gas, used in an internal-combustion engine to derive motion, or in a pump to impart motion.

2. a valve in a brass instrument, depressed to alter the pitch of a note.

Origin

C18: from Fr., from Ital. pistone, var. of pestone 'large pestle'.

Piston

A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump, the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines, the piston also acts as a valve by covering and uncovering ports in the cylinder.
