摘要： The invention relates to a sensor arrangement for determining a tank fill level of a liquid (7), especially a reducing agent for removing nitrogen from the exhaust gases of an internal combustion engine, which liquid is contained in a tank (5), at least two electrically conductive measuring electrodes (14, 16) being at least partially embedded in a carrier (8, 32) that is produced of an electrically non-conductive material. The sensor arrangement comprises a temperature sensor (44), especially a resistor (74) with negative temperature coefficient being used as a temperature sensor, which is integrated into the carrier.

摘要： The invention relates to a bypass valve for internal combustion engines, which is used for connecting the pressure side to the suction side of a charging device (24). Said bypass valve (34) comprises an electromagnetic actuator (36) and a valve housing (40) in which a closing component (41) is movably accommodated. The closing component (41) is provided with a pressure-impinged valve member (42) that can be moved in a duct (32.1, 32.2) as well as a switchable sealing element (44).

摘要： The invention relates to an oil-separating device (2) for crankcase gases in an internal combustion engine, comprising a pre-separating device (28), a cyclone separating device (30), a fine separating device (32) and an optional valve device (36), which are provided on the rocker cover (4) of the internal combustion engine in the form of a cascade. The aim of the invention is to simplify the construction of the oil separating device and to make assembly easier. Said aim is achieved, whereby the pre-separating device (28), the cyclone separating device (30), the fine separating device (32) and the optional valve device (36) are arranged on the outside of the rocker cover (4) and covered by a housing part-shell (6), which, together with the external side (20) of the rocker cover (4) forms a housing for the separating device (2).

摘要： The invention concerns an exhaust gas return valve whose valve member (15) cooperates with a valve seat (13) of a muff (8) of an exhaust gas return pipe (6), the muff (8) projecting into a pipe (1) of the intake system of an internal combustion engine, and the valve seat facing towards the inlet end of the exhaust gas return pipe (6). In this way, a valve member (15) of the exhaust gas return valve is acted upon by exhaust gas pressure in the closure direction, additionally to a pressure spring (29) against which an armature (25) of an electromagnet (20) acts in the opening direction. In order to equalize the forces acting in the closure direction, the exhaust gas is guided via a duct (42) in the valve stem (17) into a control space (41) which is sealed with respect to the pressure in the pipe (1) by a movable wall (36) with an operating surface which corresponds substantially to the operating surface of the valve member (15). In this way, the forces are equalized such that the control of the exhaust gas return valve depends only on the electromagnetic forces and the force of the pressure spring (29).
