Document Type and Number:
WIPO Patent Application WO/2021/235036
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a linear compressor with which it is possible to reduce noise and improve reliability, while reducing the size of the compressor. The linear compressor of the present invention is provided with: a casing 3; a cylinder 9 provided inside the casing 3; a piston 8 which reciprocates within the cylinder 9; an armature 5; a magnetic field element 4; a spring 6 connected to the piston 8 and to the casing 3; and a spring 7 connected to the cylinder 9 and the casing 3. Among the armature 5 and the magnetic field element 4, the one having the greater mass is mechanically connected to the one of the piston 8 and the cylinder 9 having the smaller mass, and the one of the armature 5 and the magnetic field element 4 having the smaller mass is mechanically connected to the one of the piston 8 and the cylinder 9 having the larger mass. Furthermore, the armature 5 and the piston 8 or the cylinder 9 that is mechanically connected to the armature 5, and the magnetic field element 4 and the cylinder 9 or the piston 8 that is mechanically connected to the magnetic field element 4 have substantially the same weight.
