in the bottom cylinder space, volume 2, is the useful refrigeration process of
the cycle.
4. Exhaust stroke
With the outlet valve open, the displacer moves from the top to the bottom of
the cylinder, displacing fluid from volume 2, below, to volume 1, above the dis-
placer. As it flows through the regenerator, the fluid is heated by the matrix to
near ambient temperature. This process cools the matrix ready for the gas en-
tering in the next cycle.
