An actuating drive for an adjustable actuating element may include an actuator for producing drive forces. A toggle lever may be connected to the actuating element by a first toggle lever joint. A force transmission may connect the actuator to the toggle lever. An output-side output element may be mounted pivotably on a supporting housing section of the actuating drive. The toggle lever may be connected to the output element by a second toggle lever joint. A transverse support may be oriented transversely to a linear movement direction and configured to support at least one of the toggle lever and the actuating element on a guiding housing section of the actuating device.

The invention relates to a device () for ventilating a crankcase of an internal combustion engine, comprising a ventilation line leading from the crankcase to the suction line of the internal combustion engine, an oil-mist separator () for separating the oil parts from the blow-by-gases containing the oil-mist from the crankcase is arranged in the path thereof. Also, said device () comprises a pump () which is arranged upstream of the oil-mist separator () and which is used to produce a negative pressure. The invention is characterized in that the oil-mist separator () and the pump () are embodied as connected modules thus providing a particularly compact structure.

The present invention relates to a heating device () for fuel with at least one PTC heating element () and a heat transfer device () in thermal contact with the latter, which exhibits two heat transfer elements (), and with a tubular casing () made of plastic that envelop the heat transfer device () and the a least one PTC heating element (), wherein the diesel fuel to be heated flows through the casing () and around the heat transfer device () during operation of the heating device (). Provided on the interior side of the tubular casing () is a guiding device that interacts with the at least one PTC heating element () and/or the heat transfer device () in such a way that at least one PTC heating element () and the heat transfer device () can be axially inserted into the casing () for assembling the heating device (). Of significance relative to the invention in this case is that a spring system () separate from the heat transfer device () is provided, which tensions the heat transfer device () against the guiding device so as to fix it in place.
