In an uncoupling element for uncoupling vibrations of the turbocharger of an internal combustion engine from an exhaust system with a bellows, provisions are made, especially for achieving a lower stiffness with short overall length, for the bellows to be a diaphragm bellows.

Uncoupling element

The present invention pertains to a device for cleaning gases containing particles with a bellows and with at least one filter element arranged in the bellows. To ensure effective filtration without limitation of the mobility of the bellows, the present invention provides for at least one filter element to be fixed at a bellows inner flange of a bellows corrugation in a positive-locking manner.

Device for the purification of particle-laden gases

The invention involves a device for exhaust gas recirculation of a combustion engine, with an intake module and an exhaust gas recirculation tube projecting with its gas outlet end into the intake module. Openings are created in the peripheral wall of the gas outlet end of the exhaust gas recirculation tube so that the device is easier to manufacture, wherein peripheral wall parts stay in place as bars to which a baffle plate is coupled for the exhaust gas stream.

Device for exhaust gas recirculation and process for manufacturing it

The invention relates to a device for the movable connection of pipe ends, particularly of motor vehicle exhaust systems, with a flexible pipe element, such as a metal bellows, hose or the like, and with damped, spring elastic elements acting between the connection ends of the flexible pipe element. Such a device must have a simple construction, but must on the one hand compensate the relative movements acting between said connection ends and on the other ensure the necessary restoring forces for restoring the pipe element to its central position. In such a device, the invention provides for the elements to be held in expanding fastenings of supports parts, so that the linear spring characteristic of the elements is progressively modified by the expanding fastenings.
