Looking at the following illustration, it appears to me as if the ring is being forced to the bottom of the ring groove by combustion gas pressure.
But I am thinking that the pressure on the top of the piston is so much greater than the pressure on the ring that the ring would be forced to the top of the ring groove. That is, the piston moves the ring downward and not the gas pressure.
Is my thinking wrong?
