摘要： A toothing for a gerotor pump comprises a plurality of outer teeth (10) at a gerotor inner element (1) and a plurality of inner teeth (20) greater by one at a gerotor outer element (2), wherein a centre (M1) of the gerotor inner element (1) is offset from a centre (M2) of the gerotor outer element (2) by an eccentricity (e), the outer teeth (10) thereby meshing with the inner teeth (20). A contour of the outer teeth (10) at the gerotor inner element (1) is essentially defined by a curve of a single ellipse from a tooth tip (11) continuously via tooth flanks (13) to a transition radius (14) towards a tooth space or a tooth root (12); wherein the principal axis of the ellipse is arranged radially to the gerotor inner element (1) and the centre of the ellipse determines a radius (Rmin) at the gerotor inner element (1) which corresponds to the maximum meshing depth of the gerotor outer element (2) between the outer teeth (10) at the meshing.

摘要： An adjustable lubrication oil conveying system for a combustion engine is proposed which comprises a screw pump for conveying lubrication oil with at least one screw rotatably accommodated in a screw chamber, wherein the screw pump is arranged such that a suction side of the screw chamber is connected with an intake path from an oil sump of the combustion engine, and a pressure side of the screw chamber is connected with a feed path to moving parts of the combustion engine. The lubrication oil conveying system is characterised in particular in that the screw pump is driven by the combustion engine; and towards the suction side of the screw chamber, an adjustable throttle valve is provided by means of which a flow cross-section of the intake path is gradually limitable between an opened position and a closed position. Therefore, the oil pressure in a combustion engine is, for the first time, adjusted by suction throttling in connection with a screw pump.

摘要： The invention relates to an electric coolant pump for a coolant circuit of an internal combustion engine, having a radially accelerating pump impeller and a spiral housing section of a pump housing. A control circuit is arranged about an inlet on the side of the pump housing opposing the electric engine, and is accommodated in an ECU chamber. An open side of the pump chamber and an open side of the ECU chamber are separated by a heat-exchange cover, which is opened into the pump chamber at a mouth of the inlet, wherein a material from which the ECU chamber is made has a lower heat conductivity than a material from which the heat-exchange cover is made.
