摘要： A linear motor includes a piston cylinder having a first diameter and extending along a first cylindrical axis. The piston cylinder includes a first side wall. A piston is disposed within the piston cylinder and the piston is movable along the first cylindrical axis within the piston cylinder. The linear motor includes a bearing cylinder having a second diameter and extending along a second cylindrical axis. The bearing cylinder includes a second side wall. A bearing is disposed within the bearing cylinder, and the bearing is movable along the second cylindrical axis within the piston cylinder. A linkage mechanically couples the piston to the bearing. A motor stator generates an electromagnetic field. A ferromagnetic feature interacts with the electromagnetic field generated by the motor stator to impart linear force on the piston. The second diameter is greater than the first diameter.

摘要： A linear compressor includes a cylinder that defines a compressor space and that is configured to compress refrigerant in the compressor space, a piston located in the cylinder and configured to perform a reciprocating motion in an axial direction relative to the cylinder, a mover coupled to the piston and configured to transmit a driving force to the piston to cause the piston to perform the reciprocating motion, a stator that defines a cylinder space that receives the cylinder, in which the stator is configured to generate the driving force together with the mover, and a supporting unit that includes an overlap portion that covers at least a portion of the stator, that is coupled to the stator, and that contacts the stator.

摘要： A compressor crankcase heating control method for a heat pump system includes selectively actuating a first switching device to connect and disconnect first and second power lines to and from second and third switching devices, respectively, the first and second power lines receive a first voltage. The compressor crankcase heating control method further includes, when the first and second power lines are disconnected from the second and third switching devices via the first switching device, actuating the second and third switching devices thereby connecting third and fourth power lines to ends, respectively, of at least one winding of a stator of an electric motor of a compressor. The at least one winding of the stator of the electric motor heats the crankcase of the compressor. The third and fourth power lines receive a second voltage that is less than the first voltage.

摘要： In a sealed compressor (100) of the present invention, a suction muffler (160) includes a communication pipe (162) coupled to a suction hole (151a) of a valve plate (151). The communication pipe (162) extends upward from the suction muffler (160) toward the other end of a cylinder (133), and is provided at an upper end thereof with a communication pipe exit section (162a) which is in communication with the suction hole (151a). The cylinder head (152) is formed on a lower portion with a recess (152d) accommodating the communication pipe exit section (162a) therein. A gas inflow space (152b) in the interior of the sealed container is formed between the communication pipe exit section (162) and a recess (152d). The gas inflow space (152b) in the interior of the sealed container is a space which is in communication with a sealed space inside of the sealed container (101).
