  • Patent number: 11882976
    Abstract: A liquid distributor for a liquid-transfer system of a conveyor dishwasher has first, second and third connections. The liquid sprayed in at least one final-rinse zone of the conveyor dishwasher can be fed to the liquid distributor via the first connection, wherein some of the liquid fed to the liquid distributor can be discharged, via the second connection, to a line system which can be connected to the second connection, and wherein the rest of the liquid fed to the liquid distributor can be discharged, via the third connection, to at least one line system which can be connected to the third connection. The liquid distributor has an interchangeable aperture component, which defines the fraction of liquid which is fed to the liquid distributor via its first connection and is to be discharged, via the second connection, to the line system which can be connected to the second connection.

  • Patent number: 11781639
    Abstract: An oil management system for a vehicle includes a differential housing, a transmission housing, a lubricant tank, a suction line, a lubricant pump, and an air suction pump. The transmission housing is connected to the differential housing in an air-tight manner, and a lubricant through-passage is defined between the transmission housing and the differential housing. The lubricant tank is provided in the differential housing and has a lubricant suction opening in a lower region. The lubricant pump conveys lubricant from the lubricant tank through the suction line and conducts the lubricant to the lubrication points in the differential housing and the transmission housing. The air suction pump pumps air from the lubricant tank into the transmission housing so that an excess air pressure is maintained in the transmission housing.

  • Patent number: 11691497
    Abstract: A transmission system suitable for operation with a drive machine includes an input shaft for a drive power, at least one output shaft for outputting drive power, a power-split transmission section having at least one variable transmission branch and a mechanical transmission branch, a manual transmission, a transmission system controller, and at least one first and second electric machine for generator and motor operation. The electric machines are electrically connected to one another. The drive power is divided up and conducted by the mechanical and variable transmission branch. An input-coupled, magnetically electric epicyclic gear stage brings together the variable transmission branch and mechanical transmission branch, and is activated by the second electric machine such that the output shaft of the transmission system rotates counter to a direction of rotation at the input shaft to provide a forward and reverse operation of the transmission system.
