In an exhaust-gas recycling device for an internal combustion engine, especially a diesel engine, in which the quantity of the recycled exhaust-gas part stream is controlled by an exhaust-gas recycling valve equipped with a diaphragm, the material of which can be destroyed above a specific temperature, a reliable closing of the valve before the critical diaphragm temperature is reached will be ach...

The can filling machine has a filling head which for cans of differential filling hole (3a,3b) by using one or the other of two sealing rings (29,30) of different dias., corresp. to the can dia. The filling head has two pressure chambers (9,17), with both used to press the head onto the can, when filling a larger dia. can (3a). When filling the smaller dia. can (3b), the chamber (17) is vented to ...
