Abstract
Disclosed herein is a linear compressor. In the present invention, an initial value control nut for controlling an initial position of a piston and a releasing protection nut for preventing the initial value control nut from releasing are combined in a bolt of a stator cover as a double nut method. The initial value control nut and the releasing protection nut are wound in the opposite direction. Therefore, it can prevent the initial value control nut from releasing, and can prevent the linear compressor from breaking down, thus improving the durability and the reliability.
Claims20
A linear compressor comprising:
- a stator cover fastened to a linear motor;
- a back cover spaced apart from the stator cover by predetermined distance;
- a piston which linearly reciprocates by the linear motor;
- a spring supporting member installed between the stator cover and the back cover, so as to gear with the piston;
- a main spring mounted between the spring supporting member and the back cover to elastically hold linear reciprocation of the piston;
- a connection device equipped in the stator cover to penetrate the spring supporting member and the back cover;
- an initial value control device combined with the connection device in a rear of the back cover, so as to control an initial position of the piston;
- and
- a releasing protection device combined with the connection device, so as to prevent the initial value control device from releasing.
