Abstract: A valve component includes a first disk-shaped joining part and a second disk-shaped joining part. The first disk-shaped joining part has a first opening and has an elevation in a first region of the first disk-shaped joining part which runs at least partially peripherally around the first opening. The second disk-shaped joining part is joined to the first disk-shaped joining part and has a second opening which together with the first opening defines a channel for flow of a fluid medium therethrough. The second disk-shaped joining part further has a depression in a second region of the second disk-shaped joining part which runs at least partially peripherally around the second opening and which opposes the first region of the first disk-shaped joining part. The elevation interacts with the depression in sealing fashion.

Abstract: A first clutch link for a driving clutch is capable of engaging another clutch link through interaction of a receptacle chamber and a projection. The first clutch link includes a contact surface and a counter surface, which are located on parallel planes. A hole is implemented behind the counter surface and is connected via a gap to the receptacle chamber. This hole extends parallel to the longitudinal axis of the driving clutch. A spring element is situated in the hole and has a contact area for contact on the other clutch link, which protrudes through the gap into the receptacle chamber. The hole has at least one opening, whose edge projects at least partially radially inward with respect to the hole in order to prevent the spring element from slipping through the opening of the hole.
