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.
Pump Module component. Part of the piston/cylinder set.
The head which moves inside the cylinders of a steam locomotive when pressured by steam.
A disk or short cylinder attached centrally to a rod and fitted closely inside a hollow cylinder, within which it can be driven up and down by fluid pressure (in engines).
A partly hollow cylindrical part closed at one end, fitted to each of the engine's cylinders and attached to the crankshaft by a connecting rod. Each piston moves up and down in its cylinder, transmitting power created by the exploding fuel to the crankshaft via a connecting rod.
It is a partially hollow cylindrical metal engine part with a closed end which fits into the engine cylinder. It is usually joined to the crankshaft through the connecting rod and fitted with rings to seal it in the cylinder.
the cylindrical object housed within the cylinder. Serves three purposes: 1) to bear the rotational energy from the gears and transfers it to a lateral energy 2) compresses the spring and 3) bears the piston head
Pushes air from the cylinder into the barrel
The part which compresses the combustion fuel/air mixture in the cylinder on the compression stroke. Pistons come in 3 basic flavors; domed top (high CR), flat top (standard CR) and dished top (low CR).
Component, usually in the form of a cylinder closed at one end, that converts fluid pressure into mechanical movement and force, or vice versa, within a smooth walled cylinder, in which it is a sliding fit.
A piston is a cylindrical piece of metal that moves up and down inside an engine's cylinder. It is closed at the top and mostly open at the bottom. It is attached to the connecting rod and when the fuel charge is fired, will transfer the force of the explosion to the connecting rod then to the crankshaft.
A partly hollow, cylindrical metal engine part that is closed at one end and fits into the engine cylinder. Connected to the crankshaft via the connecting rod and usually fitted with rings to seal it in the cylinder.
A piston is a round metal disk attached to a rod that moves up and down in a cylinder.
The component that moves up and down in the engine cylinder.
Attaches to the driver that moves up and down to drive nail.
A circular element that moves up and down in the cylinder, compressing the air-fuel mixture in the top of the chamber, helping to produce horsepower.
A disc which fits tightly into the back of a cartridge against its content.
A cylindrical member forming the internal element of a cylinder assembly that transmits or receives motion by a connecting rod. Fluid acts with the piston to convert pressure energy into linear motion.
The piston is a "plug" that moves up and down in the cylinder depending on the position of the crankshaft in its rotation. During 3 strokes of a 4 stroke engine the piston is pulled or pushed by the crankshaft while during the compression stroke it is pushed by the explosion of the air / fuel mixture.
A round cup that slides through the cylinders to create the flow of air through the engine and transfer the energy of combustion to the crankshaft.
Cylindrical-shaped component that forms the movable seal in a cylinder.
A cylindrical piece of metal that moves up and down inside the cylinder of a hydraulic motor.
of diesel engine, a cylindrical metallic block with a few grooves cut around the circumference at the top edge; acting together with the piston rings in the grooves, it serves to seal the compressed intake air and combustion gases in the cylinder above it and transmit the expanding gas forces downward to turn the engine via the connecting rod
Cylindrical component that slides in 3 closely-fitting metal tube or cylinder and transmits pressure. The pistons in an engine, for example, compress the fuel/air mixture, transmit the power to the crankshaft, and push the burnt gases out through the exhaust valves.
The part that moves up and down in a compressor cylinder .
A moveable cylinder that fits in a bore. Soft Pedal -The soft, springy feeling detected when the brake pedal is depressed.
A cylindrically shaped part which fits within a cylinder and is actuated by fluid pressure.
A disc with a seal that fits tightly into the back of a cartridge against the contents and serves to expel the contents.
The sliding piece that is put into motion by pneumatic pressure. Typically, pistons consist of a short cylinder fitted inside a cylindrical tube in which it moves in and out.
A short cylinder fitting closely in a tube in which it moves in two directions against a liquid or a gas.
A cylindrical part, closed at the top, that moves up and down inside the cylinder to compress the fuel/air mixture and drive the engine by means of a connecting rod, which is attached to the piston at one end and to the crankshaft at the other.
A round metal cylinder which is attached to the top end of the connecting rod, inside of the cylinder. The piston compresses the air - fuel mixture on the upward motion, and is pushed downward when the air - fuel mixture explodes. This downward motion then drives the crankshaft.
A disc which moves backwards and forwards inside a hollow cylinder.
A cylindrical piece of aluminum that moves up and down inside each of the engine's cylinders. The piston compresses the air-fuel mixture during it's upward motion and then moves back down the combustion chamber when the mixture explodes, this downward motion is what drives the crank shaft.
The piston fits into an internal cylindrical part of an engine called a sleeve and slides up and down during the combustion cycle. The piston turns the engine's crankshaft via a connecting rod, converting the energy of combustion into rotational torque. The piston and sleeve of an engine are replaceable but must both be replaced at the same time.
round, caliper component in a disc brake that is moved outward by fluid pressure to press the pads against each rotor face.
A piece of machinery that moves up and down in the cylinder to provide an engine's 'horsepower'. The piston is pulled up by the crankshaft and then pushed down again by the explosion of air and fuel in the combustion chamber, to produce a constant motion.
Solid cylinder within a cylinder pumping and compressing fluid as it moves back and forth.
In general, a piston is a sliding plug that fits closely inside the bore of a cylinder.
In optics, the term piston is simply the mean value of a wavefront or phase profile across the pupil of an optical system. The piston coefficient is typically expressed in wavelengths of light at a particular wavelength. Its main use is in curve-fitting wavefronts with Cartesian polynomials or Zernike polynomials.
