[origin: WO2022194407A1] The invention relates to a valve rotating device comprising: a valve stem seal (2) having a valve rotating device (6); a cylinder head support (8); and a spring support (10) intended to rest against a valve spring during operation. The valve rotating device is designed to rotate the spring support relative to the cylinder head support (8) during operation, and a valve stem seal, which is designed to rest against a valve stem and to seal the latter during rotational and axial movements, is fitted to the cylinder head support (8) of the valve rotating device.
