A rotary valve.

摘要

A rotary valve assembly (10) for an internal combustion engine is disclosed. The rotary valve assembly has a split housing (23; 21/22) which provides a cylindrical passage (26) within which a valve rotor (15) is located. Surrounding the valve rotor is a sealing sleeve (27) which is biased into sealing contact with the valve rotor by means of the split housing, and the split housing is sealingly connected to a head (11) of an internal combustion engine by means of an annular seal (36) having a V-shaped transverse longitudinal cross-section.
