Abstract: A subassembly and a method of producing a subassembly. The subassembly has a dividing body or separating body and at least one flow channel formed on the dividing body and extending along it with at least one flow path to influence a flow of a magneto-rheological fluid along the flow channel of the dividing body. The dividing body includes a magnetic field generation device for generating a magnetic field and a field closing device. At least the magnetic field generation device and the field closing device are filled with at least one solidifying medium using a placeholder which can be removed to form the three-dimensionally predefined flow channels on the dividing body.

Abstract: A damper has a damper chamber divided by a movable piston into first and second chambers, which are connected via a return channel, a controllable throttle valve and a connecting channel. A magnetic field source controlled by an electronic control device applies a magnetic field to a magnetorheological damping medium flowing through the throttle valve. A compensation chamber has a pre-loaded compensation volume connected to the throttle valve and the second chamber. A one-way circuit with one-way valves causes the damping medium to flow in the same direction of circulation when the piston rod plunges into the damper chamber and when it emerges therefrom. A first one-way valve on the piston allows the damping medium to flow from the second into the first chamber. A second one-way valve between the throttle valve and the second chamber allows the damping medium to flow from the throttle valve into the second chamber.

Abstract: Shock absorber for an at least partially muscle-powered bicycle having a damper device having a first and a second damper chamber assigned thereto which are hydraulically coupled with one another through a damping valve. In the damping valve a flow duct with a field-sensitive, rheological medium is provided. The damping valve has a field generating device assigned to it which serves for generating and controlling a field intensity in the flow duct of the damping valve. The flow duct comprises in the damping valve a collection chamber which is hydraulically connected with the first damper chamber through a plurality of flow apertures, wherein at least one flow aperture is configured as a through hole and at least one flow aperture, as a closable valve opening provided with a one-way valve. The collection chamber is hydraulically connected hydraulically with the second damper chamber via a plurality of fan-type damping ducts each separated from one another by a fan wall.

Abstract: A suspension fork for a bicycle has a tube system with an inner tube and an outer tube that are movable relative to one another. A damper system with a field-sensitive damping fluid is provided within the tube system. The damper device has a damper chamber that is partitioned to form a first chamber and a second chamber by a movable piston attached to a piston rod. A first throttle valve with a first field generating device and a second throttle valve with a second field generating device enable influencing the first and second throttle valves. First and second switching valves are provided. The first and second throttle valves and the first and second switching valves are interconnected such that in the compression stage there is flow only through the first throttle valve while in the rebound stage the first and second throttle valves are connected in series.

Abstract: A damper device for a bicycle suspension fork has a magneto-rheological damping medium. A piston partitions a damper chamber into first and second chambers that are connected via a return duct, an adjustable throttle valve, and a transfer duct. A field-generating device generates a magnetic field in a damping duct of the throttle valve. A one-way circuit is provided for the damping medium, with two one-way valves disposed to cause a same direction of circulation of the damping fluid both when the piston rod plunges into and retracts from the damper chamber. A first one-way valves in the piston allows a flow of the damping medium from the second into the first chamber. A second one-way valve in the transfer duct allows a damping medium flow from the transfer duct into the second chamber. The adjustable throttle valve control the plunge and the retraction of the piston rod.
