    Abstract: An oscillation-type compressor comprising: a block (302) and a piston (5); a motor (3) including a stator (3a) and a mover (3b); a movable element (12) including said motor (3b) and said piston (5); a stationary element (13) including said block (302) and said stator (3a); an elastic element (314) having a portion fixed to said movable element (12) and another portion fixed to said stationary element (13); a cylinder (4) accommodating said piston (5) so as to allow said piston (5) reciprocating in an axial direction; a displacement detector (319) connected to said piston (5) in the axial direction for detecting a position near a top dead center of said piston (5); top dead center position detecting means (320) for obtaining said top dead center position of said piston (5) based on a signal obtained from said displacement detector (319); current/voltage detecting means (321) for detecting a current or voltage value of said motor (3); and power supply means (322) for changing the voltage applied to said motor (3) based on output signals of said top dead center position detecting means (320) and said current/voltage detecting means (321).

    Abstract: Compressor is provided with an oil pump comprising an inclined passageway formed in the lower portion of a main shaft and inclined outward from below to above, a choke having a suction hole in the center that is smaller in cross section than the inclined passageway formed in the lower end of the main shaft, and a lower communicating section establishing communication between the lower end of a spiral groove and the inclined passageway, whereby the lift for the lubricating oil can be effectively increased.

    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.

    Abstract: A sealed type electrically driven compressor that efficiently pumps up a necessary amount of lubricating oil even during low speed rotation and achieves good assembling workability by a simple construction. It is provided with an oil pump comprising an inclined passageway formed in the lower portion of a main shaft and inclined outward from below to above, a choke having a suction hole in the center that is smaller in cross section than the inclined passageway formed in the lower end of the main shaft, and a lower communicating section establishing communication between the lower end of a spiral groove and the inclined passageway, whereby the lift for the lubricating oil can be effectively increased.
