  • Fastening device for connecting a valve spring retainer to a valve stem
    Patent number: 6375158
    Abstract: A fastening device for connecting a valve spring retainer to a valve stem has a clamping sleeve, which acts radially on the valve stem and which blocks the valve spring retainer axially against the force of a valve spring on the valve stem, with the valve spring retainer being held displaceably on the valve stem. In order to provide a fastening device between a valve spring retainer and a valve stem of an internal combustion engine that is functionally dependable over a long operating period and is easy to assemble and disassemble, it is provided that the valve stem has, at least in the region of the clamping sleeve, a continuous cylindrical circumferential surface and that the clamping sleeve consists of a shape memory alloy.
