Abstract: An oil pump configuration for a motor vehicle includes an oil pump having a pump part and an electric pump motor, wherein the pump part is operatively connected to the electric pump motor. The pump part and/or the electric pump motor can be mounted to a housing which at least partially delimits an oil chamber. Sealing problems at the pump part are prevented and the required installation space is low because the pump part can be mounted inside the housing and the electric pump motor can be mounted from the outside to the housing.

Abstract: The sensitivity of scattered-light fire detectors for small particles can be increased substantially when blue light is introduced into the measuring volume in addition to an infrared radiation and the scattered radiation produced by the particles is measured and evaluated separately from each other in the infrared and blue region both in the forward scattering region as well as in the backward scattering region. This can be realized by a fire detector that includes two transmitter LEDs (2.1a, 2.1b) and two photodetectors (2.2a, 2.2b), with these components being arranged such that the photodetectors receive both the forward scattered radiations as well as the backward scattered radiations of the longer and shorter wavelengths separately from each other. A multi-channel evaluation circuit is provided downstream of the photodetectors.
