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: 8757652Abstract: A valve is particularly suited for a movement damping apparatus. The valve has a field-generating device, such as a magnet unit, and a fluid that is subjected to the field, such as a magnetorheological fluid, is pressed through a flow path forming a bottleneck. At the bottleneck the fluid is subject to the field and it changes its flow characteristics in response to the field. The flow path is divided into at least two flow tracks by a partition that forms one or more additional friction surfaces.Type: GrantFiled: March 15, 2013Date of Patent: June 24, 2014Assignee: INVENTUS Engineering GmbHInventors: Stefan Battlogg, Jürgen Pösel Poesel, Gernot Elsensohn
