A transfer assembly for a mechanically controllable valve train includes a transfer member in which a valve lift adjusting device is integrated. The transfer member is configured to be operatively connected to at least one gas exchange valve directly or indirectly via a coupling element, to be movably supported in a cylinder head via a bearing, and to be operatively connected to a camshaft and to the valve lift adjusting device so that different maximum lifts of the gas exchange valve can be set.

A heat transfer unit for an internal combustion engine includes a first channel with an inlet and an outlet. The first channel is configured to have a fluid to be cooled flow therethrough. The second channel is configured to have a cooling fluid flow therethrough. A partition wall(s) is disposed to separate the first channel from the second channel. Ribs extend from partition wall(s) into the first channel and are disposed in a principal flow direction of the fluid to be cooled. The second channel comprises a first section and a second section in the principal flow direction. The ribs of the first section have a first cross section in a first flow-off portion that is constant in the principal flow direction. The ribs of the second section have a second cross section in a second flow-off portion that widens in the principal flow direction.

A heat transmission unit includes a channel conducting a coolant, and a channel conducting a fluid to be cooled. The two channels are separated from each other by a wall provided with ribs extending therefrom into at least one of the two channels. The channel conducting the fluid to be cooled includes a fluid inlet and a fluid outlet. The channel is separated by a partition wall, arranged in flow direction, into a first and a second partial channel having a first partial inlet for fluid and a second partial inlet for fluid, and a first partial outlet for fluid and a second partial outlet for fluid. At least the first partial inlet for fluid is adapted to be shut off by a first shut-off device.
