Up to the present time, the Philips’ gas-refrigerating machine has been capable of running continuously for about 2000 hr. During this time the output has gradually decreased due to clogging of the regenerator by oil. For industrial applications it would be a distinct advantage to achieve a considerably longer running time. Consequently, piston and rod sealing have been one of the main objectives of research and development on the Philips-Stirling refrigeration machine.
