It’s a dedicated hacker who has the patience to build an engine from scratch. And it’s a borderline obsessed hacker who does it twice. [Meanwhile In the Garage] is of the second ilk, and in the video ...

Description: This valve incorporates the cam-action, low-friction plug operation that provides tight shutoff over a long service life in a variety of flow control applications, including high- and low ...

How do you know when something's a genius invention? For me, it’s when I see it and instantly go: why didn’t I think of that? Today, we’re talking about one of those: the RevForce engine by Alpha Otto ...

The valves, which can move from fully-open to fully-closed in as little as 30 msec, reportedly can fit in a fraction of the package space ordinarily needed for comparably-rated valves using a linear ...

The rotary valve also means that the blockages caused by conventional poppet valves are not an issue as poppet valves are not needed in Alpha-Otto’s design. As the cylinder drops during combustion, ...

3D printing techniques enable quieter, higher performing designs for final control elements. Control valve noise is a problem in many plant environments. The sound is created by very high pressure ...

The "rotary valve" is the key to the operation of power steering. It directs the power steering fluid under pressure to either side of the rack piston, which converts hydraulic power to mechanical ...
