Abstract: A window for a grain trailer, having an oval-shaped stem with a perimeter to fit within a hole of a grain trailer having similar size and shape, the perimeter substantially uniform throughout a length of the window, an integrally-formed flange on one end of the stem, the flange having a perimeter that extends outwardly from the perimeter of the stem, a groove adjacent an end of the window and having a perimeter that extends inwardly from the perimeter of the stem. a bracket to fit within the groove and against an inside wall of the grain trailer to prevent the window from sliding out of the grain trailer, a compressible seal against a surface of the flange that faces toward the groove and seals the hole of the grain trailer such that dust and other particles cannot ingress into an interior of the grain trailer.

Abstract: An oil supply system for a machine, such as for a power unit of a motor vehicle, with a module body made of plastic including a collection tank which is divided into a prechamber and a main chamber. A predelivery pump can extract oil from the prechamber and pump it into the main chamber, a main delivery pump can extract oil from the main chamber and pump it to the machine, and a return line can return oil from the machine to the prechamber and/or the main chamber. A power unit for a motor vehicle can include such an oil supply system, wherein a predelivery suction opening is arranged on the floor of the prechamber and a main delivery suction opening is arranged on the floor of the main chamber, and the power unit is configured to be mounted in the motor vehicle with an orientation such that a line running through the two suction openings is arranged approximately parallel to the transverse axis of the vehicle.

Abstract: A gear pump having a drive shaft and at least two gear wheel pairs which each include a drive gear wheel and a driven gear wheel. The two gear wheels of a gear wheel pair are in meshing engagement with one another, and the drive gear wheels are arranged on the drive shaft and in torque-transmissive engagement with the drive shaft. The gear pump has a freely rotatably mounted shaft on which the driven gear wheels of the gear wheel pair are arranged in torque-transmissive engagement, wherein the driven gear wheels are mounted on the freely rotatably mounted shaft by means of a clearance fit.

Abstract: A liquid pump, in particular for providing a supply to a transmission of an electric or hybrid drive module of a motor vehicle, having a pump housing wherein a pump chamber and a pump rotor are arranged, wherein the pump chamber is connected to an outlet channel to which a temperature sensor is assigned, wherein the temperature sensor has a lead frame and an SMD sensor element.
