Abstract: An insulator device for a battery housing, the battery housing comprising at least one housing wall for enclosing an interior for receiving a battery cell arrangement, the insulator device comprising at least one first insulating layer arranged between the battery cell arrangement and the housing wall in the interior, wherein the at least one first insulating layer is configured for electrical and thermal insulation of the battery cell arrangement.

Abstract: A counterflow temperature control device for the temperature control of at least one object, comprising at least one first temperature control section including at least one first flow channel for a temperature control medium to flow through in a first flow direction from a first channel inflow to a first channel outflow along a first flow path, and at least one second temperature control section including at least one second flow channel for a second temperature control medium to flow therethrough in a second flow direction from a second channel inflow to an opposite second channel outflow along a second flow path, wherein the first flow direction is designed to extend substantially opposite to the second flow direction, and wherein the at least one first and second flow channels are in thermally conductive connection with the at least one object to be temperature-controlled.

Abstract: A multi-channel temperature control device with at least one temperature control body comprising at least two flow channels, each with a channel cross-section for the flow of a temperature control medium along a flow path from a channel inlet to a channel outlet, at least one distribution channel for supplying the temperature control medium to at least two channel inlets, and at least one return collection channel for discharging the temperature control medium from at least two channel outlets, wherein at least two flow channels are connected in a materially bonded or adhesive manner to at least one distribution channel and/or to at least one return collection channel, and/or wherein at least two flow channels are integrally formed with at least one distribution channel and/or with at least one return collection channel across at least a part of the circumference of the channel cross-section.

Abstract: The invention relates to an internal combustion engine comprising a turbocharger between an air filter and a crankcase, a fuel tank, and a ventilation arrangement for the fuel tank, comprising a jet suction pump.

Abstract: The invention relates to a single-stage or multistage suction jet pump comprising a propelling nozzle (5), one or more suction nozzles (2), a diffuser (7), and a volume flow limiting valve in or directly in front of the propelling nozzle. The volume flow limiting valve has a valve element (4) in the overpressure region (1) of the suction jet pump, said valve element having an opening (8) with a cross-sectional area which is smaller than the cross-sectional area of the propelling nozzle (5). The valve element spans at least one additional gap opening (9) which first releases the cross-section of the gap opening (9) when the pressure difference between the overpressure region (1) and the suction region (2) increases and which switches in the event of a defined large pressure drop and the valve element (4) reduces or closes the cross-section of the gap opening (9) such that the volume flow flowing over the opening (8) is limited to a defined level even in the event of a further increasing pressure difference.
