Publication number: 20120186921Abstract: A shock absorber for a bicycle or another, at least partly muscle-powered, vehicle has a damper device with a damper housing in which a first and a second damper chamber are separated from one another via at least one damper piston. A piston rod connected with the damper piston extends from the damper piston through the second damper chamber out of the damper housing. The first damper chamber is in communication with the second damper chamber via a flow duct that leads through the piston rod out of the damper housing toward at least one throttling device. The flow duct, at the throttling device, has a damping duct provided with a field-sensitive rheological fluid which, by way of a field generating device disposed at the throttling device, can be exposed to a field of a predetermined strength to influence the pass-through flow of the field-sensitive rheological fluid through the throttling device.Type: ApplicationFiled: January 25, 2012Publication date: July 26, 2012Applicant: DT SWISS INC.Inventors: Stefan Battlogg, Martin Walthert, Gernot Elsensohn, Jürgen Pösel

Publication number: 20120119123Abstract: 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: ApplicationFiled: July 20, 2010Publication date: May 17, 2012Applicant: INVENTUS ENGINEERING GMBHInventors: Stefan Battlogg, Juergen Poesel, Gernot Elsensohn

Publication number: 20100251574Abstract: A shoe contains an adjustable space for the foot and several fluidically connected chambers. In order to adjust the space for the foot, the flowability of a magnetorheological fluid can be influenced by one or more devices that generate a magnetic field and thereby adjust the space for the foot resulting in a better fitting of the shoe. The novel system may also be implemented in orthoses (e.g., pronation correction) or in complete shoes with orthotics devices for correcting musculoskeletal abnormalities.Type: ApplicationFiled: June 14, 2010Publication date: October 7, 2010Applicant: INVENTUS ENGINEERING GMBHInventors: Stefan Battlogg, Jürgen Pösel
