A measuring device including a Hall sensor arranged in a centrally and axially movable manner in a magnetic tube. Each half of the magnetic tube includes a north and south pole that are diametrically opposed, wherein the north pole on the first half of the tube is also diametrically opposed to the north pole on the second half of the tube, and the south pole formed on the first half of the tube is also diametrically opposed to the south pole on the second half of the tube.

A safety valve, such as for a refueling vent line between the tank filler neck and the active charcoal container in a motor vehicle. The safety valve is inserted into the refueling vent line being configured as a float valve. When fuel penetrates into the refueling vent line, and thereby into the safety valve, the outlet of the safety valve is closed by the float. The safety valve is provided with an anti-pollution pipe-end opening onto the environment and closed at normal pressure by a closure operated by a diaphragm. At an elevated pressure in the safety valve, the diaphragm effects an opening of the closure at the anti-pollution pipe-end.

A tank venting device for motor vehicles having a fuel tank, an adsorption filter connected thereto that receives the fuel vapors, an air inlet valve, and a regeneration line to the engine in which an air delivery pump is arranged. A regeneration valve controlled by the engine is provided in the regeneration line before the air delivery pump in order to control the regeneration flow rate.

A heating module for a mixture-compressing combustion engine which is arranged between an induction pipe and a cylinder head of the combustion engine. The induction pipe, the heating module and the cylinder head delimit at least one intake port in which at least one electrically heatable heating element is arranged which constitutes a component of the heating module. The heating module is connectable with connecting terminals to an electric current source and the joining surfaces between the induction pipe, the heating module and the cylinder head are sealed by a sealing device. The heating module includes at least one thin plate made of metallic material. A conductor made of electrically conductive material is secured on the plate. The sealing devices are constructed in one piece with the heating module on the side facing the induction pipe and the side facing the cylinder head.

Heating module for a combustion engine

A heating module for an internal combustion engine with external mixture formation and fuel injection and at least one intake port and one injection nozzle is disclosed. An electrically heatable heating element, which can be surrounded by flow on all sides, is arranged in the intake port, the heating element being capable of connection to an electrical power supply by means of terminals. The heating element is formed by a laminated composite part which has a trough-shaped cross section transverse to the direction of flow.
