The axial flow valve, or Thayer valve, is a brass instrument valve design patented in 1978 by Orla Ed Thayer. Designed with assistance from Zigmant Kanstul...

has led to many radical valve designs since the 1970s, such as the Thayer axial flow valve and Hagmann valve. Axial flow valves are an alternative for...

A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables...

compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially. This differs from other rotating compressors such...

An axial piston pump is a positive displacement pump that has a number of pistons in a circular array within a cylinder block. It can be used as a stand-alone...

A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening...

valve that allows blood to flow in one direction through the chambers of the heart. A mammalian heart usually has four valves. Together, the valves determine...

check valve, non-return valve, reflux valve, retention valve, foot valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through...

long travel axially (the control input) makes for a very small and precise change radially (affecting the resultant flow). Needle valves may also be used...

engines use a power valve system to get similar results to VVT. The valves within an internal combustion engine are used to control the flow of the intake and...

models employ a dual-bore slide, and many models are now made using Axial or Hagmann valves. Double slide contrabass trombones are still made by German makers...

Both free-flow and demand regulators use mechanical feedback of the downstream pressure to control the opening of a valve which controls gas flow from the...
