Abstract: A variable displacement vane pump with electronic oil pressure control provides efficient pumping of engine oil precise regulation of engine oil pressure. The variable displacement oil pump includes a rotor supported in a housing for rotation about an axis of rotation and a slide ring movably supported in the housing. A plurality of vanes extends between the rotor and the slide ring to define a plurality of variable displacement pumping chambers. An electronic drive mechanism is configured to position the slide ring with respect to the axis of rotation, and a controller is configured to drive the electronic drive mechanism for selectively positioning the slide ring to adjust an eccentricity of the slide ring relative to the axis of rotation such that the displacement of the pumping chambers is varied.

Abstract: A device for separating liquid from a gas is provided. The device includes at least one gas supply opening via which the gas can be guided in an axial direction into a separation chamber and against a baffle surface. The baffle surface deviates at least partially from a surface that is aligned perpendicular to the axial direction.
