  • Publication number: 20220105266
    Abstract: A dosing pump, in particular a microdosing pump, has a pump chamber in which a fluid inlet is provided at a first valve seat and a fluid outlet is provided at a second valve seat. A control element is coupled to an actuator to move the control element in order to vary the pump chamber in terms of volume. The control element is movably mounted by means of a flexure hinge.

  • Patent number: 11118702
    Abstract: A valve includes an electrodynamic actuator which has a magnet arrangement for generating a magnetic field and a control element movable relative to the magnet arrangement. The control element includes an energizable coil which is arranged in the magnetic field and is firmly coupled to a coil carrier. The control element is movable between at least two defined positions. There are provided permanent-magnetically interacting holding force which retain the control element in at least one of the defined positions, even when the coil is currentless.
    Type: Grant
