In a venting system, in particular for a fuel tank of a motor vehicle, which has a sorption filter for temporarily storing fuel evaporating from the fuel tank and a fluid-conveying conveying device situated between the sorption filter and an air supply or an intake manifold of an internal combustion engine, according to the present system, the conveying device is a bidirectional conveying device which is switchable in a first conveying direction in the direction of the internal combustion engine for regenerating the sorption filter and in a second conveying direction in the direction of the sorption filter for carrying out a fuel tank leak diagnosis.

Venting system, in particular for a fuel tank

A device for selectively regenerating and performing tank leakage diagnosis of a tank ventilation system has a sorption filter and a pump. The sorption filter is configured to temporarily store fuel evaporating from a fuel tank. The pump is arranged at a fresh-air side of the sorption filter and is connected in fluid-conducting fashion to the sorption filter. The pump is configured to generate a fluid flow to regenerate the sorption filter.

Device for selectively regenerating or performing tank leakage diagnosis of a tank ventilation system

Method and apparatus for detecting tank leaks, in which a gas pressure acts on a fluid which is situated in a tank, and in which the gas pressure in the tank or tank system is changed, wherein a tank leak is detected by evaluation of a temporal profile of a sum pressure of the fluid which is situated in the tank.

Servo-drive for rotary angle adjustment of an actuator for controlling

A method for positionally securing two components together, in which a hollow body is introduced into the two components. Once the final position of the components relative to one another has been established, the hollow body is driven directly into the second component with the application of axial pressure and sonic energy. The method is suitable for employment with thermoplastic components whose relative position to one another is known beforehand, an example being in the assembly of housing parts of a rotary adjuster for controlling a flow cross section in internal combustion engines.
