A linear compressor, comprises a fixed member formed with a hermetically sealed compression chamber, a movable member axially movably received in the compression chamber of the fixed member, a plurality of resilient members each intervening between the fixed member and the movable member, driving means for driving the movable member, damping means for damping vibrations of the fixed member, the damping means including a retaining member fixedly connected to the fixed member and a weight member axially movably supported by the retaining member, first detecting means for detecting a displacement of the movable member, second detecting means for detecting a displacement of the weight member, and controlling means for controlling the driving means to have the movable member perform a reciprocally linear motion to ensure that the vibrations of the fixed member are damped by the damping means.
