    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: PROBLEM TO BE SOLVED: To reduce the vibration of a vibration type compressor used for a refrigerator and air conditioner. SOLUTION: As this compressor is constituted by a weight 21, constituted so as to surround a compressor main body 2, by which the gravity center is nearly matched with the gravity center of the compressor main body 2 or the reciprocating shaft of a piston 5 and a spring 22 whose one end is installed on an air-tight casing 1 or fixed element 12 and whose other end is installed on a weight 21 and elastically deformable in the axis direction of the piston 5, the vibration exciting force of the compressor main body 2 is matched with the action point of the action force from a dynamic vibration exciting instrument and the vibration can be reduced surely.

    Abstract: PROBLEM TO BE SOLVED: To ensure the reliability by reducing the frictional wear of a slide part, in a vibration type compressor used in a refrigeration cycle. SOLUTION: This compressor is provided with a recessed part 14a continuing to the circumferential direction at the outer periphery surface of a piston 14, a slide part 14b whose one end is always faced to the inner periphery of a cylinder 4 and the communication groove 14c whose other end is not connected to the circumferential direction, positioned to both sides of the recessed part 14a at the outer periphery surface of a piston 14. The lubrication oil flow of the axial direction of the piston is improved and the lubrication oil can be supplied over the entire slide area and a drop of reliability such as the wear by the oil supply shortage of the slide part can be prevented.

    Abstract: PROBLEM TO BE SOLVED: To suppress a sliding loss and to enhance operation efficiency by providing a fixed element constituted of a stator of a motor and a cylinder, a moving element constituted of a mover of the motor and a piston and an elastic element whose part is fixed to the moving element and the fixed element and forming a recessed part in a sliding part of the cylinder and the piston. SOLUTION: When a motor 3 is energized, a mover 3b fixed to a piston 14 is sucked in a magnetic pole direction of a stator 3a, continuously, the mover 3b is pushed in an opposite direction with elastic force stored in an elastic element 8 disposed between the mover 3b and a block 6 and the piston 14 is reciprocated in an axial direction by this repetition. As a result, coolant gas is led to a compression chamber 9 within a cylinder 4 via a low pressure chamber 7a, and after coolant gas is compressed, coolant gas is discharged via a high pressure chamber 7b. At this time, sliding loss is reduced by reducing sliding area of the piston 14 and the cylinder 4 and an efficient operation is realized by forming recessed parts 14a of a plurality of lines which are not continuous in an edge peripheral direction and extend in the axial direction on an outer peripheral part of the piston 14.
