description A liquid-phase cooling device of a refrigeration system has an outer tubular housing enclosing a heat exchanger through which a mixture gases and liquid constituting a working fluid media is heated and cooled while undergoing compression and expansion within a cavity formed in the outer tubular housing at an axial end portion thereof closed by an electromagnetic actuator under selective control of an electrical power source through which operation of the heat exchanger is effected. The actuator has a casing attached to the outer tubular housing of the heat exchanger at said axial end thereof within which a diaphragm attached to the axial end of the casing is exposed to the working fluid media within the cavity enclosed by the outer tubular housing of the heat exchanger. The diaphragm is engaged by a piston within the casing for axial deformation thereof to effect said compression and expansion of the fluid media under selective control of electrical current supplied from the power source to an electromagnetic coil through which a magnetic field is established within a body of magnetostrictive material disposed within the actuator casing between the piston and an end cap closing the axial end of the casing opposite the axial end to which the diaphragm is attached.
