A separate actuator on the piping releases pressure in the line if it crosses a threshold. This releases the pressure on the back of the seal, causing the valve to open. The essential parts of a PORV are a pilot valve (or control pilot), a main valve, a pilot tube, the dome, a disc or piston, and a seat. The volume above the piston is called ...
A complete restoration includes not only repair of the parts that can be seen – the body, trim, chrome, wheels, and the passenger compartment – but also the components that are not necessarily visible or otherwise evident, including the engine and engine compartment, trunk, frame, driveline, and all ancillary parts like the brakes ...

A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance.
The axial flow valve, or Thayer valve, is a brass instrument valve design patented in 1978 by American inventor Orla Ed Thayer. [1] Designed with assistance from instrument maker Zigmant Kanstul, it was originally intended to replace the traditional rotary valve on the French horn , but instead revolutionized the design of trombone valve ...
The twin Moog servo valves are used to deform the shape of the die on this blow molding accessory designed by BMC Controls Limited. One example of servo valve use is in blow molding where the servo valve controls the wall thickness of extruded plastic making up the bottle or container by use of a deformable die. [10]
The type of jet engine used to explain the conversion of fuel into thrust is the ramjet.It is simpler than the turbojet which is, in turn, simpler than the turbofan.It is valid to use the ramjet example because the ramjet, turbojet and turbofan core all use the same principle to produce thrust which is to accelerate the air passing through them.
An incident occurred at unit 2 on 10 December 2020 at 12:22. Because of valve repair work, excessively hot water flowed to the reactor water clean-up system filters. The hot water dissolved materials from the filters. When the clean-up system was restarted, the dissolved materials flowed to the reactor core, where they became radioactive. This ...
