A temperature-controlled battery, for a vehicle drive, has numerous flat battery cells electrically interconnected and which are combined parallel to each other and are distributed in several battery chambers in a thermally insulated battery housing to form cell packages. Spacers are arranged between the battery cells. A flowable first heat-transfer medium in contact with the battery cells is enclosed in the battery housing. The first heat-transfer medium exchanges heat with a second heat-transfer medium enclosed in a channel system via the heat-transfer surfaces enclosed in the battery housing. The channel system has a supply line and a discharge line leading out of the battery for the temperature-controlled exchange of heat outside the battery. For forced convection at the battery cells, at least one pump is enclosed in the battery housing. The pump has a flow connection to the first heat transfer medium on the supply and outlet sides.

The invention relates to a device for the variable actuation of gas exchange valves for internal combustion engines, wherein at least one cam (2) pertaining to a camshaft (1) mounted in a housing rotates according to the engine speed. The cam (2) first drives an intermediate member (4) which performs a clear oscillating, rotary movement and has a rotational axis (7) that can be displaced in the housing parallel to itself along a curve of displacement (8), said intermediate member comprising a control cam (5) having a lifting region (5b) and actuating an output member (11) that, in turn, actuates at least one valve (13). The aim of the invention is to enable one such device to be reliably controlled. To this end, the control cam (5) has a catch region (5a), and the intermediate member (4) is mounted on a bearing having an axis which corresponds to the rotational axis (7), said bearing being arranged in such a way that it is guided in a forced manner and can be displaced parallel to the curve of displacement (8, 28, 35), by means of an articulation (16, 24, 26) connected to the cylinder head or the housing or by a slide (34) that is guided in the housing in a positively locking manner. The invention also relates to a method for operating an internal combustion engine comprising a plurality of cylinders using at least one of the inventive devices.

A disc clutch wherein at least one first clutch disc, having internal teeth mating with the external splines of a first rotary hub, frictionally engages at least one second clutch disc, having external teeth mating with the internal splines of a second rotary hub coaxial with the first hub, when the clutch is engaged. Engagement of the clutch takes place in response to actuation of a cylinder-piston unit having a reciprocable piton which can directly or indirectly bear upon one of the two outer discs of the package including the first and second discs. The splines of the hubs and/or the teeth of the clutch discs are capable of undergoing deformation, particularly elastic deformation, to thus facilitate a more accurate selection of the magnitude of torque to be transmitted between the hubs by way of the frictionally engaged clutch discs.

The seal or pattern between two machine parts has on one of the sealing gap-forming, facing surfaces (5) a plastic layer (1) with closely juxtaposed depressions (8) which have the form of partly cut off voids of an expanded plastic structure. They are formed by the removal of a plastic layer (3) expanded on the machine part, the layer thickness being so uniformly reduced that the voids (4) of the bottom void layer (4) adjacent to the base surface (5) of the machine part are open. This avoids the insulating action of the closed voids of an expanded plastic layer and the latter has a very limited weight, which avoids any risk of the layer being detached or separated due to centrifugal forces. Moreover, in simple manner, a honeycomb-like, open surface structure is obtained, so that there is a labyrinth effect in the sealing gap. In order to obtain minimum, sealing gaps by running in the open, honeycomb-like surface structure is particularly advantageous, because the solely linear contact which occurs ensures a rapid running in of the mating surface, which can be abrasively prepared. The seal or packing is particularly suitable for very rapidly rotating machine parts.

A heat exchanger unit is disclosed, the heat exchanger unit including a first tube element unit, a second tube element unit, and an engine machine apparatus having an expansion step unit and a compression step unit. Each of the tube element units is adapted to condition a fluid flowing therethrough. Desirably, the fluid is compressed in the compression step unit and expanded in the expansion step unit in such a manner that technical operation is transferred from the expansion step unit to the compression step unit so that an inner recovery of energy is made possible.

The invention is characterized in that the gas exchange valves of a cylinder are displaced in a displacement unit (15, 34) jointly and independently of the displacement of the displacement devices of the other cylinders. Every displacement unit (15, 34) is associated with separate actuators for actuating the same. Angle of rotation sensors (42, 43) are provided to detect the angle or rotation signals of the crankshaft and the camshaft or any other shaft rotating at half the crankshaft speed. These angle of rotation signals are used to derive the common idle phase of all valves of a cylinder to be jointly adjusted, a control unit (44) effecting the displacement of every displacement unit (15, 34) during said common idle phase.
