Patent number: 9874195Abstract: A pressure-measuring glow plug device includes a module housing, a glow plug configured to ignite a combustion mixture in a combustion chamber of an internal combustion engine, and a pressure-measuring device. The pressure-measuring device has a pressure sensor configured to detect the pressure in the combustion chamber. The glow plug is connected to the module housing by a flexurally elastic membrane. The force acting on the glow plug in the combustion chamber is transferred to the pressure sensor, which is supported on a supporting element by a preloading force. The supporting element is fastened rigidly to the module housing by a sensor housing. The glow plug device further includes a separate loading sleeve that is connected at one end to the pressure-transferring piece and at the other end to the supporting element. The loading sleeve is configured to apply the preloading force for the pressure sensor.Type: GrantFiled: April 30, 2013Date of Patent: January 23, 2018Assignee: Robert Bosch GmbHInventors: Janpeter Wolff, Wolfgang Koetzle

Publication number: 20150135811Abstract: Described is an elastic diaphragm for a pressure-measuring device for ascertaining a pressure in a combustion chamber of an internal combustion engine, especially a self-ignitable internal combustion engine, the diaphragm being accommodated in a housing of the pressure-measuring device in order to separate a pressure chamber from a cavity and in order to seal the housing from the pressure to be measured. The diaphragm has a pressure-application region. Furthermore, the diaphragm is developed in the shape of a ring and in cross-section has a U-shape that is open toward the cavity; the region of the diaphragm on which the pressure is acting is geometrically made up of two interconnected quarter circles, so that the pressurized region has a structure that is self-supporting with respect to the arising combustion pressure loads.Type: ApplicationFiled: April 30, 2013Publication date: May 21, 2015Inventors: Janpeter Wolff, Wolfgang Koetzle, Thomas Hauber, Stefan Leopold, Denis Gugel
