  • Bistable actuator, actuator arrangement, method for actuation and use
    Patent number: 9689408
    Abstract: A method for bistably actuating an actuator includes applying positive pressure in an actuator fluid supply that is fluidly connected to an actuator chamber by means of an actuator fluid supply connection, wherein a working positive pressure is generated in the actuator chamber, whereby an actuator element fluidly connected to the actuator chamber is brought from a resting position to an actuation position, pressure-tight sealing of the actuator fluid supply connection, so that the working positive pressure in the actuator chamber is maintained and the actuator element remains in the actuation position.
