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).
