Abstract: A linear motor of the present invention has: a stator having a stationary iron core and a magnet wire; a mover having a moving iron core and a magnet; and a plate-shaped elastic member for supporting the mover in a manner to rock in the rocking directions. This construction eliminates a sliding portion for supporting the mover so that it can reduce the loss, which might otherwise accompany the reciprocation of the mover. Moreover, a linear compressor using this linear motor is high in efficiency and reliability.

Abstract: A reciprocating linear motor (3) for a compressor comprises a stator (3a) with a ring coil (106) embedded in an annular segmented yoke (104). Each segment (104a-d) of the yoke (104) has a central part (80) consisting of laminations (70) of higher permeability and outer parts (90,101) made from a material of lower permeability and lower electrical conductivity.

Abstract: A vibrating compressor which may be employed in refrigerators is provided which includes an elastic mechanism designed to produce reaction against movement of a piston through a moving mechanism such as an electric motor to oscillate the piston to change the volume of a compression chamber. The elastic mechanism consists of a plurality of discs connecting at the center with the piston. Each of the discs has slits curved in a scroll fashion to form spring arms. The discs are laid to overlap each other and shifted in angular position from each other so that the arms of one of the discs coincide with the slits of adjacent one of the discs, thereby avoiding direct contact of the arms of adjacent two of the discs.
