Flow divider valve: a valve providing a plurality of output flows from a single fluid source [2] Flutter (Heimlich) valve: a specific one-way valve used on the end of chest drain tubes to treat a pneumothorax; Foot valve: a check valve on the foot of a suction line to prevent backflow
Pneumatic valve springs are metal bellows filled with compressed air [1] used as an alternative to the metal wire springs used to close valves in high-speed internal combustion engines. This system was introduced in Formula One in 1986 with the Renault EF-Type .

Valve guides are typically shaped in a tube with a flare at one end. Their replacement involves removing the worn part by driving it out with a hammer and specifically-shaped punch. Installation may involve shrink-fitting , heating the cylinder head and cooling the valve guide so as to ease insertion, then driving the new guide in quickly with ...
The effective mass of a traditional valve with spring includes one-half of the valve spring mass for symmetric springs and all of the valve spring retainer mass. However, a desmodromic system must deal with the inertia of the two rocker arms per valve, so this advantage depends greatly on the skill of the designer.
The following table gives formula for the spring that is equivalent to a system of two springs, in series or in parallel, whose spring constants are and . [1] The compliance c {\displaystyle c} of a spring is the reciprocal 1 / k {\displaystyle 1/k} of its spring constant.)
A flat spring fixed only at one end like a cantilever, while the free-hanging end takes the load. Coil spring Also known as a helical spring. A spring (made by winding a wire around a cylinder) is of two types: Tension or extension springs are designed to become longer under load. Their turns (loops) are normally touching in the unloaded ...
A swing check valve (or tilting disc check valve) is a check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow. The seat opening cross-section may be perpendicular to the centerline between the two ports or at an angle.
