Patent number: 9719574Abstract: Shock absorber and method for operating a shock absorber for a bicycle wherein a relative motion of a first and a second component interconnected via a damper device is dampened. The damper device includes a controllable damping valve with a field generating device with which a field-sensitive medium can be influenced for influencing a damping force of the damper device by applying a field intensity of the field generating device.

Publication number: 20150285326Abstract: 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.Type: ApplicationFiled: August 27, 2013Publication date: October 8, 2015Applicant: INVENTUS ENGINEERING GmbHInventors: Stefan Battlogg, Michael Kieber, Juergen Poesel

Patent number: 9126625Abstract: Closed-loop control of an energy absorber acting as a damper between two parts that are movable relative to one another. A damping force of the energy absorber, or damper, can be adjusted by way of the change in the viscosity of a magnetorheological fluid (MRF), which change can be influenced by a magnetic field of a coil. According to the method it is possible to decelerate an impact or a movement with the lowest possible forces in order to minimize possible consequential damage/loading by way of setting as constant a deceleration as possible, as small a deceleration as possible, by way of using the entire available deceleration travel, and low or zero residual speed at the end of the deceleration travel independently of the moving mass or speed.Type: GrantFiled: May 10, 2011Date of Patent: September 8, 2015Assignee: Inventus Engineering GmbHInventors: Stefan Battlogg, Jürgen Pösel, Gernot Elsensohn

Patent number: 8985149Abstract: A valve device is formed with a through-channel and a field generating device. A fluid which can be influenced by a field is provided in the through-channel and the field generating device is configured to act on the field-influenced fluid in the through-channel by way of a field. At least one adjustment device is provided with which the field that is active in the through-channel can be adjusted. A portion of the cross-sectional area of the through-channel can be adjusted, the portion being exposed to a field of a specific intensity so that the through-channel can also only partly be exposed to a field of a specific intensity. Thus, the through-channel, as seen in the direction of the flow, can be divided into regions of different flow resistance, whereby characteristic curves, which were previously attained only with difficulty, are easily obtained when using the valve device in a damper, for example.Type: GrantFiled: July 20, 2010Date of Patent: March 24, 2015Assignee: Inventus Engineering GmbHInventors: Stefan Battlogg, Juergen Poesel, Gernot Elsensohn
