Definitions

n.名词 noun

1
- : a disk or cylindrical part tightly fitting and moving within a cylinder, either to compress or move a fluid collected in the cylinder, as air or water, or to transform energy imparted by a fluid entering or expanding inside the cylinder, as compressed air, explosive gases, or steam, into a rectilinear motion usually transformed into rotary motion by means of a connecting rod.
- : a pumplike valve used to change the pitch in a cornet or the like.

as inmotor

Synonyms

Froghoppers produce suction power with a pumplike structure in their heads, where muscles pull on a membrane to generate negative pressures, akin to a piston.
A steam engine is a device that transforms energy of one sort into energy of a different sort, and it can perform useful tasks, such as moving a piston, without ever violating that principle of conservation of energy.
It is a very simple plan, and will be perfectly tight; it is by restoring an equilibrium on both sides of the piston.
The water-piston is 10 inches in diameter, drawing and forcing 35 feet perpendicular, equal beam.
When she had finished her up-stroke the steam passed from under the pole on to the top of the piston in the cylinder.
Then he came down from London and found that the piston of his engine was half an inch smaller in diameter than the cylinder.
The steam in ordinary working was shut off when the piston had moved from an eighth to a quarter of its stroke.
