Claims

[Scope of Claim for Utility Model Registration] 1. A horizontal compressor in which an electric motor and a compression mechanism driven by the electric motor are housed in a sealed casing, and the inside of the sealed casing is divided into a motor chamber and a compression chamber by a partition plate. A horizontal compressor, characterized in that the outer circumferential portion of the partition plate is brought into surface contact with the inner circumferential wall of the hermetic casing by elastic force. 2. The horizontal compressor according to claim 1, wherein at least the outer peripheral portion of the partition plate is made of an elastic material. 3. The partition plate is formed of a highly elastic plate-shaped disk, and its outer periphery is curved so as to expand toward the rear in the insertion direction, while the outer diameter of the insertion tip of the partition plate is equal to the inner diameter of the sealed casing. The horizontal compressor according to claim 1, which is smaller in size and has an outer diameter at its insertion rear end larger than the outer diameter of the closed casing. 4. The partition plate is fixed to the main bearing of the compression mechanism, and a boss hole into which the boss of the main bearing is fitted is bored in the center of the partition plate,
3. The horizontal compressor according to claim 3, wherein slits extending in the axial direction are formed on the outer periphery of the partition plate at intervals in the circumferential direction. 5 A plurality of elastic inward protrusions are formed in the boss hole formed in the center of the partition plate, and the partition plate is press-fitted and fixed to the boss of the main bearing by the inward protrusions. Horizontal compressor according to scope 4. 6. The horizontal compressor according to claim 2 of the utility model registration, wherein the elastic body is a leaf spring. 7. The horizontal compressor according to claim 2, wherein the elastic body is a sealing ring attached to the outer periphery of the disk-shaped partition plate, and the outer periphery of the partition plate is formed of the elastic body by this sealing ring.
