Abstract
The riveting sleeve (6) described is used to connect the component parts (3, 4, 5, 10, 11) of compressor valves (2). The riveting sleeve (6) passes through the valve parts (3, 4, 5, 10, 11) to be connected to one another and is provided with at least one radial groove (16, 22, 26) which starts from the inner or outer generated surface (17, 18) thereof and weakens the wall thickness of the riveting sleeve (6) in this area. On the other side of the generated surface (17, 18) the groove (16, 22, 26) is adjacent either to the wall of a valve part surrounding it or surrounded thereby, or it has opposite it a recess (19, 23, 27) in the valve part (3, 5, 25) adjacent to the riveting sleeve (6). By upsetting the riveting sleeve (6) by means of an applied axial force, the riveting sleeve (6) is deformed radially outwards or inwards in the manner of a bead, it being securely clamped in or on the adjacent valve part. If a recess (19, 23, 27) opposite the respective groove (16, 22, 26) is provided, the said recess (19, 23, 27) is filled with the deforming material of the riveting sleeve (6) and in this way a secure and play-free connexion is produced.
