Abstract

1,108,097. Refrigerating. GENERAL MOTORS CORPORATION. 18 Aug., 1966 [25 Aug., 1965], No. 370301/66. Heading F4H. A combined Stirling engine and Stirling refrigerator comprises a cylinder 12 and two displacers 14 and 16 forming three working volumes 18, 20 and 22 connected through regenerators 24 and 26, the energy input to the system being provided by a heating coil 17, and the displacers being connected in a spring mass system so as to vibrate under the influence of pressure changes in the system at such a resonant frequency as to provide the necessary thermodynamic motion. A cooling coil 19 is provided and refrigeration occurs at a coil 21. A suitable spring system is illustrated in Fig. 3, in which the displacer 16 is formed as a differential piston with smaller and larger upper and lower faces sliding on an enlarged portion 32 and a stem portion 34 respectively of a stud 28 connected to the cylinder. The upper displacer 14 has a stem 44 provided with a disc 46 sliding within the enlarged portion 32 of the stud 28. Springs 42 and 48 act, both in tension and compression, between the first displacer and the stud and between the second displacer and the stud, and a spring 56 acts between the two displacers. A solenoid 66 is provided to act through an armature 64 on the upper displacer to start the system. In an alternative spring system, Fig. 6 (not shown), the springs connecting the two displacers and the upper displacer and the stud are disposed in the working space between the two displacers. The cycle operates with the lower displacer leading the upper by 90 to 120 degrees.
