Definition of piston in English: pistonnoun ˈpɪst(ə)nˈpɪstn 1A 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. 活塞 Example sentencesExamples - Modified piston valves were also fitted to counteract the high coal consumption as the originals became worn.
- Another system uses hydraulic pistons that mount to a wood platform.
- Adkins' solution was to affix his gas piston to the standard recoil spring plug.
- Each explosion would release enough force to push the piston.
- A hydraulic hammer is basically a hydraulically powered reciprocating piston inside of a body.
- The aluminum block has ductile iron cylinder liners and is filled with JE pistons.
- The bore is often pitted and the gas piston is usually corroded.
- When the trigger is pulled, the compressed air expands and drives the piston forward.
- The force of the resulting explosion pushes the piston down the cylinder for the exhaust stroke.
- The engine's camshaft drives the pump pistons through a roll rocker arm.
- The piston in its cylinder rocked, trembled, didn't move.
- The resulting explosion pushes a piston, which is attached to a connecting rod.
- The cylinders have to be right and their fit with the piston rings perfect.
- Besides leaving salt deposits, rusting internal parts and causing valve damage, water in an engine also makes short work of pistons and cylinders.
- The stroke is the distance that the piston moves up and down.
- Jet engines are crucial: They're faster than piston engines and far safer.
- Then the piston moves back up to compress this fuel/air mixture.
- The central control circuit then sends a control signal to the driver's circuit for the accumulator piston.
- The five mobile panels (one flap, four sliding) are activated by hydraulic pistons.
- The resulting explosions of fuel and air drive the pistons which turn the crankshaft.
- 1.1 A valve in a brass musical instrument in the form of a piston, depressed to alter the pitch of a note.
(铜管乐器上的)活塞阀键 Example sentencesExamples - It is in C, a tone above the euphonium, and reaches the lowest notes with the aid of six pistons; its upward range is much greater than that of the larger tubas.
- The valves and pistons on a trumpet are very delicate - and essential.
OriginEarly 18th century: from French, from Italian pistone, variant of pestone 'large pestle', augmentative of pestello 'pestle'. The Latin pistullum meant pestle (Middle English) and is the source of the botanical pistil (early 18th century) from its similar shape. From the same source Italian formed pestone for a large pestle or rammer, and this, via French, is the source of piston.
