Abstract: An actuator-damper unit for use in orthotic or prosthetic devices. The actuator-damper unit includes a housing which may be fastened on the orthotic or prosthetic device and in which a cylinder is formed. A first piston is displaceably mounted in the cylinder and is coupled to a piston rod. The piston rod is disposed, via a first end, on the first piston and may be coupled, via a second end, to the orthotic or prosthetic device. The first piston separates two fluid chambers in the cylinder from each other and forms a piston-cylinder unit, wherein at least one further piston is coupled to the first piston in order to form at least one further, variable-volume fluid chamber.

Abstract: A joint device with an upper part and a lower part which are mounted on each other so as to be pivotable about a pivot axis, a hydraulic unit secured on the upper part and the lower part, and a housing in which a cylinder is arranged. A working piston is arranged in the cylinder and is coupled to at least one spring mechanism which transmits tensile forces and compressive forces and which engages on at least one abutment arranged displaceably inside the cylinder.

Abstract: An orthopedic joint device is provided, the device having an upper part, a lower part pivotably mounted thereon and an actuator fastened to the upper part and the lower part and having a drive shaft coupled to an output element via a force transmission device, the force transmission device having a load transmission element that can by adjusted depending on the load.

Abstract: The invention relates to an actuator for an orthopedic device with an actuator housing and a heat store for storing the heat produced during operation of the actuator, the heat store having a heat store housing that has a cavity and a heat storage medium present therein, or consisting of a heat storage medium. The heat store is designed to be attachable to or in the actuator housing and has a receiving region that matches an actuator housing region and, when the heat store is mounted, is in heat-transferring contact with the actuator housing.

Abstract: A joint device of an orthosis with an upper part and with a lower part that is arranged on the upper part in an articulated manner, with a first fastening device for securing the upper part to a patient and a second fastening device for securing the lower part to a limb, wherein the joint device connects the upper part to the lower part in an articulated manner and has an upper part binding and a lower part binding via which the upper part and the lower part can be secured to the fastening devices, wherein the joint device has at least four degrees of freedom.

Abstract: The invention relates to a device (40) for magnetically axially supporting a rotor, which rotor comprises a thrust bearing plate (32) connected to the rotor, in a magnetic thrust bearing (54) having at least two independently controllable bearing branches (3, 4, 41) which each comprise at least one coil (5, 42), wherein magnetic flux isolation of the bearing branches (3, 4, 41) is provided, which flux isolation consists in that at least two of the bearing branches (3, 4) are arranged one after the other in the circumferential direction and have a single common pole (9) which has a circularly closed circumference, the center point of which is arranged on the axis of rotation (35) of the rotor, wherein the coils (5) surround pole segments (11) connected to the common pole (9) and wherein the common pole (9) is arranged either radially inside or radially outside of the pole segments (11), and/or in that the thrust bearing plate (32) is divided into at least two coaxial plate parts (46, 61) which are associated w

Abstract: Disclosed is a flywheel (13) comprising a rotating element (13?) which rotates in relation to an axis of rotation and includes a radially outer flywheel mass member (24) that adjoins an inner shaft connection part (26) and tapers in the radial direction such that hollow projecting end pieces (24?) are formed. The external face of the outer flywheel mass member (24) has a radial indentation (25) that extends all around the flywheel mass member.
