  • Fluid metering valve
    Patent number: 11578685
    Abstract: A motorised fluid metering valve includes an inlet pipe, a discharge pipe and a motor moving a piston that can move linearly between a closed position in which a distal end of the piston sealingly engages with a seat of matching shape, and an open position. The valve is configured to have a flow rate that varies continuously between the closed position and the open position depending on an axial position of the piston. The inlet pipe opens in a periphery of the discharge pipe, with a constant protuberance regardless of the position of the piston, the protuberance not extending radially beyond a barycentre of the discharge pipe. Also, the motor is a rotary electric motor moving the piston in translation.
