Abstract: An exhaust gas feed device for an internal combustion engine includes an exhaust gas recirculation duct comprising an end, an outlet, and an outflow cross-section. An air intake duct opens into the exhaust gas recirculation duct. A flow-guiding element is arranged in and at the end of the exhaust gas recirculation duct. An exhaust gas recirculation valve comprises a regulator body. The regulator body is configured to control the outflow cross-section. A valve seat is arranged at the outlet at the end of the exhaust gas recirculation duct in which the flow-guiding element is arranged. The valve seat is configured to limit the outflow cross-section of the exhaust gas recirculation duct.

Abstract: The invention refers to a device (11) for flanging the end (13) of a metal tube (13) to achieve a circumferential surface extending outward at right angles from the tube (13), comprising a flanging tool (17) adapted to be attached to the end of the tube (13), the flanging tool (17) having a guiding arrangement (31) drivable by a shaft (33, 48) of the guiding arrangement (31) and a pressure element (27) attached to the guiding arrangement (31), the guiding arrangement (31) comprising shifting means (35) driven by the rotating (89) shaft (33, 48) for shifting the pressure element (27) in an outward radial direction (37) with respect to the tube (13).

Abstract: A device is indicated for flanging the end of a metal tube to achieve a circumferential surface extending outward at right angles from the tube. It has the form of a cylindrical housing with a flange at its open end for fastening a clamping tool which is fastened to the tube, and its other end is closed by a bottom part. The housing has a flanging attachment that is able to rotate around the longitudinal axis of the housing, and a hand-wheel which is attached to a connecting element and extends outward through the bottom part. The hand-wheel is rigidly linked to a guide part of the flanging attachment by a threaded rod which fits through a suitably threaded bore in the bottom of the housing. A pressure element of the flanging attachment is guided by a pin which also forms part of the flanging attachment. The pressure element is operationally attached to the guide part so that it is able to rotate with it around the longitudinal axis of the housing.
