Abstract: An air mass flowmeter with a housing having an air-guiding path in which an air mass sensor element is arranged on a sensor element carrier in the housing and is electrically connected to a circuit carrier by connection wires. The circuit carrier is also arranged in the housing the air mass sensor element is positioned accurately in the air-guiding path by a positioning element that engages into a positioning element receptacle formed in the sensor element carrier.

Abstract: The transmission includes at least ten gear-selection pressure chambers which are provided for the selection of a plurality of transmission gears, at least two actuation valves, each of which is provided for setting at least one actuation pressure for the gear-selection pressure chambers, at least one first selection valve unit, at least one second selection valve unit, and at least one third selection valve unit which are provided for connecting the actuation valves to the gear-selection pressure chambers. The second selection valve unit is directly connected to four gear-selection pressure chambers in order to transmit actuation pressure and the third selection valve unit is directly connected to six other gear-selection pressure chambers and directly to the second selection valve unit in order to transmit actuation pressure.

Abstract: In a hydraulic control arrangement for an automated shift transmission, in particular a dual clutch transmission in a motor vehicle including a hydraulic control arrangement, the hydraulic control arrangement has a main pump and a controllable additional pump which jointly ensure that oil is supplied to the hydraulic control arrangement. The additional pump can feed into a control channel of a lubricating pressure slide and build up an adjustable lubricating fluid control pressure. The lubricating fluid pressure in the lubricating cooling system is adjusted in a simple and inexpensive manner by lubricating pressure slide changes modifying the lubricating control pressure in the lubricating cooling system.

Abstract: A sensor device has a sensor element, two connecting elements configured as a wire and are led out of the sensor element, and a supporting element having a supporting body and two supporting feet to support the temperature sensor in a housing. The two connecting elements, the sensor element and the supporting body bound between themselves a two-dimensional clearance of a predefined width and height. A minimum dimension of the sensor element and the length and height of the supporting feet are dimensioned, relative to the clearance, such that neither the sensor element nor one of the supporting feet can enter the clearance of an adjacent sensor device.

Abstract: One or more contact elements for transmitting calibration data during the calibration of a sensor of the sensor device are electrically connected to a signal processing unit of the sensor. The contact element has a contact region in a groove of a housing part of the sensor device. A sealing compound, which seals the contact region, is introduced into the groove and a cover is brought into contact with the sealing compound in the groove. The groove, the sealing compound, and the cover are configured and they interact in such a way that the chamber communicates only with a working medium which is to be sensed by the sensor.
