Patent number: 6422070Abstract: Devices for measuring the mass of a flowing medium using a temperature-sensitive measuring element have the disadvantage that considerable measuring errors may occur in the event of a pulsating flow characterized by flow fluctuations. In order to counteract these measuring errors, the device (1) possesses an axially extending measuring duct (33), in which a temperature-sensitive measuring element (20) is accommodated. The measuring duct (33) extends from the inlet mouth (36) to a deflecting duct (34), out of which the flowing medium flows out from an outlet orifice (46) without any axial distance from the inlet mouth (36) and radially underneath the latter. The invention is provided for measuring the mass of a flowing medium, in particular for measuring the intake air mass of internal combustion engines.Type: GrantFiled: May 30, 2001Date of Patent: July 23, 2002Assignee: Robert Bosch GmbHInventors: Klaus Reymann, Dieter Tank, Uwe Konzelmann, Henning Marberg

Patent number: 6318170Abstract: A measurement device for measuring the mass of a medium flowing along a flow direction, in particular the intake air mass of an internal combustion engine, has a plate-shaped sensor element, which is inserted into a recess of a sensor support. The sensor element includes a membrane that supports a measuring element, which membrane encloses a hollow space embodied in the sensor element on the side remote from the sensor support. The sensor element is secured in the recess by means of a glue between the sensor support and a bottom face of the sensor element oriented toward the sensor support. According to the invention, the glue constitutes a glue seam that extends around the hollow space of the sensor element between the sensor support and the bottom face of the sensor element and is only open on the side remote from the flow direction by means of at least one recess in order to ventilate the hollow space.Type: GrantFiled: September 20, 1999Date of Patent: November 20, 2001Assignee: Robert Bosch GmbHInventors: Erhard Renninger, Hans Hecht, Gerhard Hueftle, Uwe Konzelmann, Matthias Kallabis, Andreas Stark, Michael Rudloff, Henning Marberg
