On the face of it that looks like a reasonable idea.. Is it your own idea or one you came across? There would be a lot of face to face friction/wear on the moving component and also the sealing of it could be quite tricky. None the less it is an interesting principle.
The design could be made into a double sided combustion chamber as it currently only looks like the upper chamber fires. The lower one could fire at 180degs to this as well. Would balance loading on the upper and lower faces.

Next issue is transfer of the power to an output shaft. The shaft will have linear movement FWD and AFT as it rotates so it would need to be on a spline of some sort. I think that would promote a lot of wear on the spline as it moved back and forth as well as being under torque. I expect there are other ways around that.

Sore this back in 2012 and if i remembered correctly they made a working version but the energy produce wasnt much more than the energy required to move the parts in the first place, so the output was very weak.
