Abstract
A compressor assembly for use with a Pulse Tube cryocooler is disclosed. The compressor assembly includes a central hub having a plurality of faces, and at least four compressor modules mounted on the central hub. Each of the compressor modules is mounted on a face of the plurality of faces. Each compressor module comprises a piston mounted in the central hub and configured to reciprocate along an axis of travel within the central hub. The pistons are mounted head-to-head with each other and collective reciprocation of the pistons along the respective axes minimizes vibration forces of the compressor assembly in X, Y, and Z translational axes of motion.
