A rotary valve assembly 24 for controlling intake and exhaust of gases to and from working chambers 12 of an I.C. engine, a fluid motor or a gas compressor comprises an intake port, an exhaust port, and, when used in an I.C. engine, an ignition hole which may be accommodated in a ceramic sleeve 28. Rotatably disposed within the sleeve is a valve body 56 having a valving combustion chamber 108 open to the working chamber 12. A ceramic segment seal member 119 movably mounted on the valve body has sealing surfaces engageable with the sleeve 28. A face seal 61 is located between a head plate 17 and the rotatable valve body 56. The valve body and segment seal member 119 are rotatably driven to sequentially align the valving combustion chamber 108 with the intake port, ignition hole, and exhaust port during operation. <IMAGE> |
