  • Piezoelectric valve
    Patent number: 6994110
    Abstract: The valve comprises a mobile needle having a movement in the valve body which is controlled by an amplified piezoelectric actuator. A bellows, surrounding an intermediate zone of the needle, is integral at a first end with the valve body and at a second end with the needle so as to isolate the actuator from the pressure chamber. At least one flexible guide blade of the needle is fixed on the one hand to the valve body and on the other hand to the needle. This flexible guiding enables any part sliding with respect to another part, liable to generate wear or contaminating particles, to be avoided, except for the seat and needle.
