Abstract

PURPOSE:To decrease an oil-up rate while enabling oil, contained in gas fluid of flowing in a horizontal casing, to separate, and further by suppressing lubricating oil, accumulated in the bottom part in the casing, from being rolled up by the gas fluid, by a simple constitution. CONSTITUTION:In a horizontal scroll compressor, a compression element P and a motor 5 are internally mounted to a horizontal casing 1 to also open a suction pipe 13 to a motor side chamber S1. An oil separator, having a collision wall 82 opposed to an opening part of the suction pipe 13 and an opening part 83 opened in a direction orthogonal to the suction pipe 13 and further toward a suction port 6 of the compression element P, is provided in this casing 1. The opening part 83 of this oil separator is opposed to the suction port 6, to provide oil dropping space T for dropping down oil, separated in the oil separator, to a downward side from the opening part 83, between these opening part 83 and suction port 6.

In the compressor described above, after the oil mixed in the gas fluid flowing into the casing A is separated by the oil separator E as described above,
Only the gas fluid is sucked into the compression element B from the suction port D to be compressed. In the compressor having the above structure, the oil separator E is provided with the opening of the suction pipe C and the suction port. Since it is provided so as to block the front of the opening of the suction pipe C with respect to D, the gas fluid that has collided with the oil separator E is not directly sucked into the suction port D, but the bottom portion inside the casing A. Since the distance between the suction port D and the bottom portion where the oil is stored is not sufficient because it is horizontal, the suction port while winding up the lubricating oil stored in the bottom portion of the casing A. D will be sucked into the compression element B. Therefore, the lubricating oil rolled up by the gas fluid is also sucked into the compression element B together with the gas fluid, which causes a problem that the so-called oil rising rate increases.

As described above, according to the present invention, in the horizontal casing 1, the collision wall 82 facing the opening of the suction pipe 13, and the suction port 6 of the compression element P in the direction orthogonal to the suction pipe 13 are provided. An oil separator 8 having an opening 83 opening toward the front is provided, and the opening 83 of the oil separator 8 is opposed to the suction port 6, and between the opening 83 and the suction port 6, The oil separated by the oil separator 8 is introduced into the opening 8
By providing the oil spilling space T that is dropped from 3 to the lower side, the gas fluid introduced into the motor side chamber S1 through the suction pipe 13 collides with the collision wall 82 and mixes with the gas fluid. After separating the oil that has been stored, the gas fluid can be directly sucked into the suction port 6 from the opening portion 83, and the lubricating oil stored in the bottom portion of the casing by the gas fluid as in the conventional case. The problem of winding up the oil can be eliminated, and the oil separated by the collision wall 82 can be surely returned to the inner bottom portion of the casing from the opening 83 through the oil drop space T. The rising rate can be reduced.

The opening 83 is formed in the oil separator 8.
By providing a gas fluid outlet port 84 that is open at one side in the circumferential direction of the casing 1 at a position that is orthogonal to the opening direction of the casing 1, a part of the gas fluid from the suction pipe 13 is removed from the gas fluid outlet port 84 to the casing. Can be introduced in 1.
Since the introduced gas fluid can be swirled along the inner peripheral surface of the casing 1, the motor 5 can be cooled by the gas fluid.

Even if the oil separated on 2 is carried to the suction port 6 by riding on the flow of the gas fluid without flowing down from the oil drop space T, the oil flows into the suction port 6. It can prevent you from doing it. Therefore, the separated oil becomes
It is possible to surely return to the inner bottom portion of the casing 1 without remixing with the gas fluid sucked into the casing, and to reduce the oil rising rate.
