...engines or turbines, in which case they are referred to as air starters.

Piston Rings

(106 companies)
Piston rings are used for sealing cylinders. They can work at higher temperatures than elastomeric, fabric, or polymer seals.
...reciprocating compressors and rotary compressors. Reciprocating compressors utilize the thrust of a crankshaft-driven piston moving within a cylinder to create the motive pressure. Rotary compressors move gas through the system by the motion of rotating...

Drum Pumps

...specific. There are a number of variations of positive displacement pumps. Diaphragm and piston pumps, which drive fluid via a pulsed discharge, are the most common drum types. For more information on these different types of pumps, visit IEEE...

Liquid Handling Pumps

(2,399 companies)
The moving parts in these pumps operate in either a rotary or reciprocating manner. Rotary. Rotary pumps use a rotor to move fluid, where parts (gears, ridges, vanes, etc.) of the rotor act as dividers between chambers. As the rotor rotates, liquid...
...have fixed-volume chambers. Beyond this distinction, each type differs based on its specific mechanism for fluid compression. The five main types of compressors are piston, rotary, screw, scroll, and centrifugal. Piston Compressors. Piston compressors...

Metering Pumps

...of these include fixed speed, variable speed, electric drive, solenoid drive, and magnetic drive. The drive mechanism translates the rotary motion of the driver into reciprocating movement. Industrial duty metering pumps will submerge this portion of the pump...

Air Cylinders

...differential in the cylinder chambers. One side of a piston flange can be pressurized to provide force and motion with a spring (providing return force after pressure is released), or both sides can be alternately pressurized for bi-directional powered...

Hones and Honing Tools

(143 companies)
...and honing tools include width, rotary speed, and shank or bore diameter. Hone width is measured in English units such as inches (in), feet (ft), and yards (yd); or in metric units such as millimeters (mm), centimeters (cm), and meters (m). Typically...

Engine Starters

(55 companies)
Engine starters provide the initial rotation for internal combustion engines. They cause the pistons to move before ignition, enabling the engine to turn over so that it can then operate under its own power.

Air Compressors

(1,185 companies)
...for industrial applications. There are three basic types of air compressors: reciprocating, rotary screw, and centrifugal. Reciprocating air compressors use pistons to compress the contents of an air cylinder and force them into a storage tank...

...pressures. There are many variations of positive displacement pumps, all of which are described in IEEE GlobalSpec's Pump Types page. This video depicts the operation of a hydraulic piston pump developed by Graco Dispensing Machinery. Video Credit: Era...

Aircraft

...as a glider in instances of engine failure. Rotary wing aircraft spin rotors at a rate to create upward lift. While not as fast as planes, rotary wing aircraft have better maneuverability. Rotors are essentially large, vertical-axis propellers. The most common...
Grinders and grinding machines use an abrasive that is bonded to a wheel, belt or disc to remove material and improve surface finish. Devices can be pneumatically driven or powered by a combustion engine or electric motor. Grinders and grinding...
...a reciprocating or rotary mechanism. Most rotary types use a drive rather than a lever or crank. In reciprocating type hand pumps, a hydraulic or pneumatic piston is used to create the pressure needed to move the media. Hydraulic pumps - pumps which...
