Two-gauge pressure regulator connected to gas cylinder used for breathing gas supply. Pressure regulators are used with diving cylinders for Scuba diving. The tank may contain pressures in excess of 3,000 pounds per square inch (210 bar), which could cause a fatal barotrauma injury to a person breathing it directly. A demand controlled ...
Cylinder valve – a shutoff valve directly coupled to the cylinder shell at the neck or boss which is opened to allow gas flow into or out of the cylinder, and closed to prevent such flow. It usually has a threaded inlet/outlet opening to which other equipment can be connected, but in some cases may have an integral pressure regulator on the ...
The crankcase air outlet, where the PCV valve is located, is generally placed as far as possible from the crankcase breather. For example, the breather and outlet are frequently on opposite valve covers on a V engine, or on opposite ends of the valve cover on an inline engine. The PCV valve is often, but not always, placed at the valve cover ...
an inlet or exhaust valve in a piston engine or compressor; a direct coupled valve to control the flow of gas into or out of a gas storage cylinder. a scuba cylinder valve to control the flow of gas into or out of the diving cylinders of a scuba set; a valve to control flow of the actuating fluid into or out of a hydraulic or pneumatic cylinder
The word poppet shares etymology with "puppet": it is from the Middle English popet ("youth" or "doll"), from Middle French poupette, which is a diminutive of poupée.The use of the word poppet to describe a valve comes from the same word applied to marionettes, which, like the poppet valve, move bodily in response to remote motion transmitted linearly.
A cylinder manifold is system of pipes and valves for using a group of gas cylinders, or boil-off from vacuum insulated evaporators, to feed a single supply line.The advantages of the manifold system as compared with using a single cylinder are increased capacity and reliability, and also the possibility of a centralized supply for multiple users.
Stiffer valve springs can help prevent valve float and valve bounce but at the expense of increased friction losses, higher stresses, and more rapid wear in the valvetrain. Various techniques have been used to offset the effect of stiffer springs, such as dual-spring and progressive-sprung valves, roller-tipped tappets, and pneumatic valve ...
