摘要： A linear compressor vertically mounted inside a hermetic shell (8) and including: a reference assembly with elements including a block defining a cylinder (2); a resonant assembly with elements including an actuator (4) that carries a piston (1); and a linear electric motor including a magnet member (5) and a coil (6) for driving the actuator that reciprocates the piston (1) within the cylinder (2). There are provided: a first resilient element (20) mounted between the resonant assembly (1, 4, 5) and one end of the shell (8); a second resilient element (21) mounted between the reference assembly (2) and the other end of the shell (8); and a third resilient element (22) mounted between the reference assembly (2) and the resonant assembly (4), with the first and the second resilient elements (20, 21) applying opposite forces to the shell (8) upon reciprocation of the piston (1).

摘要： A linear motor and a linear compressor including said motor. The linear motor comprises a set of inner laminations (90), forming the stator, mounted around the outer circumference of a fixed member (60), and a set of outer laminations (30) mounted spaced from the inner laminations (90). An actuator (85) is connected to a movable member (80) and carries a magnet member (86) in the space defined between the inner laminations (90) and the outer laminations (30). The upper ends of the inner laminations (90) and outer laminations (30) are connected by a connecting element (100) made of a non-magnetic material, in order to stabilize the laminations and serve as a suspension mounting for the set of outer laminations (30). Application of electric current to a coil (95) causes the actuator (85) to move and carry the movable member (80) with it. The fixed member (60) is defined by the cylinder of the compressor and the movable member (80) by the piston, which is reciprocated inside the cylinder to compress a refrigerant gas, and the connecting element (100) does not contact the cylinder. This arrangement does not require any special configuration of the cylinder or use of an additional plate to provide the connection to the outer laminations.

摘要： A system for adjusting resonant frequencies in a linear compressor comprising, in the interior of a shell: a linear motor (20): a cylinder (1); a piston (10) reciprocating inside the cylinder (1); and an actuating means (9) operatively coupling the piston (10) to the linear motor (20), said system comprising: a detecting means (D) to detect a load imposed to the linear motor (20), in an operational condition of the latter related to the gas pressure in the discharge thereof; and a frequency adjusting means operatively associated with the detecting means (D) and with the resonant assembly, in order to define, as a function of said operational condition, a frequency adjustment, by varying at least one of the values related to the mass of the resonant assembly and to the average stroke of the piston (10), to a value of the mechanical resonance frequency corresponding to the electrical supply frequency.
