When the hot side piston temperature rise, thus causing pressure on the piston are moved to the right, and when the heat until the temperature stability. The pressure will be reduced.
When the Pistons summer temperatures increase. The pressure piston is moving to the right. And heated until the temperature constant. The pressure is reduced
When the piston of the hot temperature increase. Thus, causing the pressure piston is moving to the right. And when be heated until the temperature stability, the pressure is reduced.
