摘要：A valve rotator is effective between a valve stem of an internal- combustionengine and a support, normally the cylinder head. The rotator comprises an upper springplate, a lower spring plate spaced along an axis below this upper plate, a compressionspring braced axially between the plates, a two-part link element having an upper partrotationally secured to the valve stem and a lower part rotationally fixed in at least onerotational direction relative to the axis on the lower plate, and a unidirectional clutchbetween the lower part and the support and permitting the lower part to rotate aboutthe axis only in the one direction relative to the support. Normally the lower plate isrotatable relative to the upper plate and the lower part is generally cylindrical, centeredon the axis, and fixed rotationally on the lower plate. The clutch is also normally providedbetween the lower plate and part and the support. Such a rotator is connected with theclutch so that it turns with the valve.
