PUSH-PULL COMPRESSOR HAVING ULTRA-HIGH EFFICIENCY FOR CRYOCOOLERS OR OTHER SYSTEMS

摘要

A method includes generating a first varying electromagnetic field using a first voice coil of a first actuator. The method also includes repeatedly attracting and repelling a first magnet of the first actuator based on the first varying electromagnetic field. The first voice coil is connected to a first piston of a compressor, and the first magnet is connected to an opposing second piston of the compressor. Attracting the first magnet narrows a space between the pistons, and repelling the first magnet enlarges the space between the pistons. The method may further include generating a second varying electromagnetic field using a second voice coil of a second actuator and repeatedly attracting and repelling a second magnet of the second actuator based on the second varying electromagnetic field. The second voice coil may be connected to the second piston, and the second magnet may be connected to the first piston.
