A propellant valve (100) includes a ferromagnetic shell (102) and a pair of coils (106A, 106B) within an opening (104) of the ferromagnetic shell. The propellant valve includes a bobbin (108) extending from an upper section (102A) of the ferromagnetic shel...

A reduced gain thrust control valve (10) for use in a rocket engine has a housing with a fluid inlet and a piston and cylinder unit (14) for controlling a fluid output of the control valve. The fluid inlet is formed by at least one metering element (30) fo...

The method involves determining a law of variation of coefficient of pressure drop of a liquid in a pneumatic or hydraulic device, based on a specific angle, through a preset choice of the shape of an orifice of a fixed grid of a valve, independently of an...

The method involves providing a shutter to define a control range satisfying a fixed precision of pressure loss or stability of an operating point of a hydraulic or pneumatic system. The shutter selects center or width of the control range based on frontal...
