Abstract: A coolant delivery device for an internal combustion engine, in particular for a motor vehicle, includes a pump, a an activatable electric motor, a shut-off valve, a return line, a heating device, and a common module housing. The pump is configured to deliver liquid coolant, and includes a suction port configured to connect to a tank, and a pressure port for the coolant and which is assigned to the engine. The motor is configured to drive the pump. The valve is assigned to the suction port. The return line is configured to connect to the tank, and includes at least one check valve. At least the pump, motor, valve, heating device, and the at least one check valve together form a delivery module and are positioned in the common module housing.

Abstract: A water injection device of an internal combustion engine, including a water tank for storing water, at least one water injector, a conveying element for conveying water from the water tank into the water injector, and a shut-off element, which is situated in an area between the conveying element and the water injector, and which is configured to maintain a system pressure between the shut-off element and the water injector at a level such that water situated in the area is prevented from evaporating. An internal combustion engine, which includes a water injection device.

Abstract: The invention relates to a holding-down means (100) for fixing battery cells (2) in a battery submodule (70), comprising positioning elements for positioning the holding-down means (100) relative to the battery cells (2), and comprising guide elements for guiding cell connectors (80) which connect the battery cells (2), wherein gas-venting openings which pass through from a top side to a bottom side are provided in a central region of the holding-down means (100), and wherein the sealing elements which surround the gas-venting openings are provided on the bottom side of the holding-down means (100). The invention also relates to a battery submodule (70) which comprises a plurality of battery cells (2) and cell connectors (80) which connect the battery cells (2), and also at least one holding-down means (100) for fixing the battery cells (2).

Abstract: A water injection device of an internal combustion engine is provided. The water injection device includes a water tank for storing water, and a delivery element for delivering the water. The delivery element is connected to the water tank. The water injection device further includes at least one water injector for injecting water. The at least one water injector is connected to the delivery element. The water injection device further includes a pressure sensor, which is arranged in a line region between the delivery element and the water injector, and a control unit, which is designed to determine, on the basis of pressure data of the pressure sensor, a formation of vapor in the aforementioned line region when the water injector is closed and the delivery element is deactivated.
