Abstract:
A cryocooler is described that can include a pressure wave generator, and a refrigeration device (for example, a cold-head), which can be used to liquefy a gas when the gas is exposed to a surface of the refrigeration device. The pressure wave generator can include one or more motors. Each motor can include a stator, and at least one electrical coil wound around a portion of the stator. The electrical coil can generate a reversing magnetic field when alternating electric current is passed through the electrical coil. The motor can further include a pressurized container that can be placed within the space enclosed by the stator, and a piston that can be placed inside the pressurized container. The stators can be placed external to the pressurized container. The piston is made by combining magnets that have opposite and transverse polarities, and are combined adjacently on a common reciprocating axis.

Claim (Index 1):
A pressure wave generator for an acoustic load comprising:\n a. a stator including a pair of magnetic pole faces defining a space therebetween; b. a pressure cylinder received within the space defined between the magnetic pole faces of the stator; c. an electrical coil wound around a portion of the stator external to the pressure cylinder and configured to receive an alternating electrical current such that electromagnetic fields of alternating directions are formed between the pair of magnetic pole faces; d. a piston configured to slide linearly within the pressure cylinder, said piston including a first permanent magnet portion and a second permanent magnet portion, said first and second permanent magnet portions being transversely oriented so as to assert opposite magnetic fields and configured so that the piston reciprocates within the pressure cylinder as an alternating electrical current is applied to the electrical coil; e. said pressure cylinder including a sealed first end and containing a gas between the sealed first end and the piston so that a gas spring is formed between the sealed first end and the piston; f. said pressure cylinder including a second end including an opening configured to communicate with an acoustic load so that pressure waves of a working fluid are generated within the pressure cylinder between the piston and the second end of the pressure cylinder as the piston reciprocates, where the pressure waves exit the pressure cylinder via the opening.
