A fluid valve includes a valve member located between a first cavity and a second cavity, and an actuator that includes a pilot. The valve member is moved by the balance between the pressure prevailing in the first cavity and the pressure prevailing in the second cavity. The valve member includes a longitudinal hole that can be blocked by the pilot so as to modify the pressure prevailing in the first cavity and the force acting on the valve member so as to vary a fluid flow rate between an inlet and two outlets. The valve member is attached to a piston, one end of which is located in a third cavity. The force acting on the valve member is determined by the pressures prevailing in the various cavities.

Fluid valve

A fluid valve is suitable for use with a hydraulic circuit of an item of aircraft equipment. The fluid valve includes a valve body having one inlet, two outlets and a communication channel with an external pressure source. The fluid valve further includes an electric solenoid actuator located in the valve body and having a movable ferromagnetic pilot. A valve member is movable inside valve body to at least partially block a passage between said inlet and one of the two outlets. The valve member at least partially defines first and second cavities. A fixed limiter is disposed within the communication channel such that a displacement of the movable pilot causes a variation in pressure in one of the first and second cavities to produce a force for moving the valve member.

Fluidic valve

The present application relates to a valve for a cryogenic gas. The valve includes a body with a main inlet, a main outlet, and a main passage. The valve also includes a main shutter for the main passage, the main shutter including an auxiliary inlet, an auxiliary outlet, and an auxiliary passage, in which an auxiliary shutter is arranged, which includes a closing surface configured to close the auxiliary outlet and be able to drive the main shutter in the closing direction, and a drive surface configured to drive the main shutter in the opening direction, while resting on the edge of the auxiliary inlet and blocking the auxiliary inlet partially in order to brake the flow there. The drive surface is formed by drive lugs which are connected to a head of the auxiliary shutter. The lugs form a bayonet coupling between the shutters. The present application also relates to an electrovalve.

Aerospace electrovalve for high-pressure cryogenic gas

The present application relates to an electromagnetic valve, in particular for high-pressure cryogenic gas for a rocket. The valve includes a body in which a passage is formed connecting an inlet to an outlet, a seat communicating with the passage, a ball sealing the seat when the valve is at rest, a magnetic circuit with a coil, a magnetic shell, and a plunger displacing the ball relative to the seat thereof in order to open and/or close the seat. The plunger is telescopic, i.e., extendable and retractable. The plunger includes two ferromagnetic portions that are movable relative to one another and relative to the passage. The portions are fitted one inside the other and define air gaps Eand Etherebetween. The valve includes a magnet and a spring on either side of a secondary portion to hold the secondary portion in the closed position, distancing a ball from the exhaust seat.

Electromagnetic valve for high-pressure cryogenic gas

An arming and safety device for a pyrotechnic chain, the device including a housing presenting an inlet zone for a pyrotechnic stream and an outlet zone for the pyrotechnic stream, an arming element housed in the housing between the inlet and outlet zones and adapted to move between a disarmed position in which it blocks the passage of the pyrotechnic stream and an armed position in which it allows the pyrotechnic stream to pass, and an electric motor for driving the arming element. The stator of the electric motor is situated outside the housing, and the rotor is contained entirely inside the housing.
