Abstract: A beverage held in a container is rapidly cooled by placing the container in a flexible sleeve defining a sleeve chamber that is cooled, either directly or by a secondary loop of heat transfer fluid, by a closed refrigeration circuit. An agitation assembly is selectively operable to oscillate the sleeve about a yaw axis. During active cooling, a cooled fluid (such as refrigerant or a secondary heat transfer fluid) flows through the sleeve chamber while the agitation assembly is simultaneously operated to rapidly cool the beverage held within the container.

Abstract: The invention refers to a linear compressor, comprising: a shell (20); a cylinder (30) affixed to the shell (20) and defining a compression chamber (C); a piston (40) to be displaced in reciprocating movement in the interior of the compression chamber (C) during the operation of the compressor; a linear electric motor (50) mounted to the shell (20); and an actuating means (60) operatively coupling the piston (40) to the linear electric motor (50), in order to make the latter displace the piston (40) in a reciprocating movement in the interior of the compression chamber (C), the actuating means (60) being coupled to the piston (40) by an elastic means (70), so that the actuating means (60) and the piston (40) be displaced in phase opposition during the operation of the compressor.

Abstract: A compact compressor comprising a first tubular housing portion; a second tubular housing portion having a first end region open to the first tubular housing portion and a second end region defining a compression chamber and housing a piston; an electric motor carried by the first tubular housing portion; a driving means connecting the piston to the electric motor; a valve plate seated against the second end region of the second tubular housing portion; and an end cover fixed to the second tubular housing portion and acting against the valve plate and providing, internally and through the valve plate, fluid communications between the compression chamber and the suction line and discharge line of a refrigeration circuit to which the compressor is coupled.
