A pressure sensor for a brake booster includes a housing that receives a pressure sensor element and which has a first fluid connection, via which the pressure sensor can be connected to the brake booster. The housing has a second fluid connection with a receiving opening which at least partly receives a flow valve and a connection socket for a vacuum pump, wherein the flow valve releases the flow of fluid in the direction of the vacuum pump and blocks the flow of fluid in the opposite direction. The flow valve is designed as a membrane insert and is inserted into the receiving opening.

An angle sensor for determining a rotation angle of a rotatable body, such as a steering column in a motor vehicle, includes a gear wheel. The orientation of a magnetic field generated by the gearwheel is configured to be detected by a magnetic field sensor. The gear wheel is comprised of a magnetisable material, such as hard ferrite, into which a magnetization is introduced. The gear wheel is stronger in a central region than in an edge region in which the teeth are arranged. In order to weakly magnetize the edge region, which minimizes a negative influence of the teeth on the homogeneity of the generated magnetic field, the front face of the gear wheel is configured to be magnetized. The magnetization process advantageously takes place at the same time as an injection moulding process to form the gearwheel. A method is implemented to produce the gear wheel.
