0 (in engines, pumps etc) a round piece usually of metal that fits inside a cylinder and moves up and down or backwards and forwards inside it. -- píst
The role of flowcontrol valve and quick exhaust valve are to control the speed of piston.
The piston of linear cylinder normally operates in the forward and backward direction with two-control position valves.
The resonant frequency of each mode can be separately adjusted by means of two piston tuners.
This is because we feel that the oscillating piston problem, although interesting, lacks direct practical application.
Consumers consistently endorsed large-capacity double-action piston machines that were sturdy, hand-powered, labour-intensive, and mechanically reliable.
This paper describes a theory for a piston-operated compressor in which shock waves are used to heat the gas being compressed.
A rather dynamic plasma channel is formed under the compression by a magnetic piston in the fast capillary discharge channel.
However, the pressure acting on the front face depends on the motion of the piston and on the compression waves generated by it.
