ABSTRACT:
A linear compressor is provided which may be employed in refrigerators or air conditioners. The linear compressor includes a compressor mechanism disposed within a hermetic casing. The compressor mechanism includes a linear motor which makes a piston reciprocate within a cylinder and a piston oscillation controller. The piston oscillation controller controls oscillations of the piston so as to bring an actual top dead center position of the piston into agreement with a reference top dead center position and alters the reference top dead center position based on a given parameter such as an ambient temperature or a required thermal load of, for example, a refrigerator. An improved structure of the linear motor is also provided.
