Publication number: 20220403941Abstract: A device for controlling a flow rate and expanding a fluid in a fluid circuit. The device is formed with an enclosure and a valve element arranged inside the enclosure. The valve element which is arranged movably in a linear movement in the direction of a longitudinal axis relative to the enclosure has a sealing surface and a control area formed at a first end face of the valve element and arranged adjacent to the sealing surface in the axial direction. The sealing surface is formed as a lateral surface of a straight circular cylinder with a constant outer diameter. An outer diameter of a surface of the control area corresponds to the outer diameter of the sealing surface. The control area has throughflow apertures and at least one control aperture. The valve element in the control area is formed with a substantially hollow circular cylindrical-shaped wall.Type: ApplicationFiled: November 12, 2020Publication date: December 22, 2022Inventors: Carsten Ohrem, Daniel Zens, Gregor Dünnwald

Patent number: 10151277Abstract: A device of a system for air ducting of an internal combustion engine in a motor vehicle with a turbocharger arranged between an exhaust gas line and an intake line. The device includes a high pressure flow pathway with a valve branching from the exhaust gas line between the internal combustion engine and a turbine side of the turbocharger, a low pressure flow pathway with a valve branching in the flow direction of the exhaust gas downstream from the turbine side of the turbocharger, and an exhaust gas heat exchanger. A first flow pathway with a valve and a second flow pathway with a valve merge into a mouth region with a third flow pathway. At least one section of the high pressure flow pathway, the low pressure flow pathway, the flow pathways, and the exhaust gas heat exchanger are integrated inside a housing formed as a continuous compact unit.Type: GrantFiled: October 7, 2015Date of Patent: December 11, 2018Assignee: HANON SYSTEMSInventors: Carsten Ohrem, Peter Diehl, Stojan Cucuz
