Pneumatics uses compressed air as a drive medium. The company manufactures cylinders, [4] valves, valve systems, [5] as well as units for compressed air preparation and is increasingly focusing on electronic networking of system parts. Vacuum technology for non-contact transport systems, such as those used in the food industry [6] is an ...
A camless or free-valve piston engine is an engine that has poppet valves operated by means of electromagnetic, hydraulic, or pneumatic [1] actuators instead of conventional cams. Actuators can be used to both open and close valves, or to open valves closed by springs or other means.
Pneumatic cylinder, also known as air cylinder, is a mechanical device which uses the power of compressed gas to produce a force in a reciprocating linear motion. [ 1 ] : 85 Like in a hydraulic cylinder , something forces a piston to move in the desired direction.
Pneumatics (from Greek πνεῦμα pneuma 'wind, breath') is the use of gas or pressurized air in mechanical systems. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other ...
Pneumatic tubes (or capsule pipelines, also known as pneumatic tube transport or PTT) are systems that propel cylindrical containers through networks of tubes by compressed air or by partial vacuum. They are used for transporting solid objects, as opposed to conventional pipelines which transport fluids.
Pneumatic actuator operating a valve through a rack-and-pinion mechanism. [7] A pneumatic actuator is similar to a hydraulic one but uses a gas (usually air) instead of a liquid. [8] [9] Compared to hydraulic actuators, pneumatic ones are less complicated because they do not need pipes for the return and recycling of the working fluid. On the ...
Compressed air is commonly also used, at lower pressures, to control the engine and act as the spring force acting on the cylinder exhaust valves, and to operate other auxiliary systems and power tools on board, sometimes including pneumatic PID controllers. One advantage of this approach is that, in the event of an electrical blackout, ship ...
Hydropneumatic refers to the pneumatic (gas) and hydraulic (water) components needed for operation of the devices. Hydropneumatic accumulators or pulsation dampeners are devices which prevent, but do not absorb, alleviate, arrest, attenuate, or suppress a shock that already exists, meaning that these devices prevent the creation of a shock wave ...
