本発明は、横形ロータリ式圧縮機に係り、特に摺動部の
信頼性を向上した横形ロータリ式圧縮機に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a horizontal rotary compressor, and particularly to a horizontal rotary compressor with improved reliability of sliding parts.

造である。The structure of a conventional compressor is described in Japanese Patent Application Laid-Open No. 59-21838.9, and will be explained with reference to FIG. 4. Case 1
A compression element consisting of a frame 4, a shaft 7, a cylinder 8, a roller 9, a sub-bearing 10, etc. and a motor 6 are housed inside the case 1, which is sealed by a lid 2 and a welded part 3, and a frame 4 which is connected to the case and welded part. This structure is connected by 5.

ル状であり、油１５を吸込み確実な給油を可能にする。Oil 15 is stored at the bottom of the case 1, and due to the reciprocating movement of the vane 13 of the compression element, the lubricating oil 15a of the sliding part is transferred from the suction piece 12 to the center of the shaft 7 via the oil discharge port 11 and the oil supply pipe 14a. The oil is sent to a provided oil reservoir 7a, reaches an oil groove 7C provided on the outer periphery of the shaft through a horizontal hole 7b, and lubricates the outer periphery of the shaft 7. here,
The suction piece 12 has a tapered inner diameter and a nozzle shape, and sucks in the oil 15 to enable reliable oil supply.

も高価であった。This suction piece 12 is formed by drawing a thin plate. Such conventional compressors do not take into consideration the following points. That is, as mentioned above, welding is essential in the manufacturing process of compressors, and electric welding is generally used. During welding, a large amount of hard metal spheres of several micrometers to several hundred micrometers, generally called spatter, are scattered. Some of the spatter 16 may enter the inside of the case 1 and adhere to the inner wall of the case 1, and furthermore, some of the spatter 16 accumulates together with the oil 15 at the bottom of the case. This is sucked up into the sliding part together with the lubricating oil 15a. As a result, the spatter 16, which is smaller than the clearance of the sliding part (generally about 10 micrometers), may enter the clearance and damage the outer circumferential surface of the shaft 7, potentially causing a locking accident. As a countermeasure to this problem, it is known to install a filter at the oil intake port,
It has been difficult and expensive to manufacture a filter that captures spatter smaller than 0 microns without reducing the amount of oil supplied.
本発明の目的は、信頼性に優れた横形ロータリ式圧縮機
を提供することにある。An object of the present invention is to provide a horizontal rotary compressor with excellent reliability.

磁石を設けたことを特徴とする。In order to achieve this object, the present invention is characterized by having a lubricant suction portion and a lubricant discharge portion (both of which are provided with a magnet for attracting spatter).
以下、本発明を図面により説明する。 Hereinafter, the present invention will be explained with reference to the drawings.
第１図は本発明の一実施例の構成を示す圧縮機の縦断面
図であり、第２図は第１図のＡ部分の拡大図である。FIG. 1 is a longitudinal sectional view of a compressor showing the configuration of an embodiment of the present invention, and FIG. 2 is an enlarged view of portion A in FIG. 1.
第１図において、第４図と同一符号は同一、又は均等部

永久磁石にょう捕えられるものである。The effect of attracting the spatter 16 with this configuration will be explained with reference to FIG. 2. In FIG. 2, lubricating oil 15a
The spatter 16 that has passed through the oil suction piece 21 at the same time is
After passing through the piece part, the oil passes near the outer wall surface of the tip of the oil suction piece 21 due to the vortex of oil generated at its outlet.
It can be captured by a permanent magnet.
また、第１図の実施例において、吸込ピース以外に油吐

ことかできる。FIG. 3 is a diagram showing the configuration of an embodiment of the pond, which is the main part of the present invention, in which a small piece of a permanent magnet 23 is arranged on the oil outlet side of the oil suction port 12 formed by drawing a thin plate. Similar to the above action, the lubricating oil 15a containing the spatter 16 is transferred to the small pieces 23 of the permanent magnet due to the oil vortex generated at the nozzle outlet.
Since the spatter 16 passes near the sputter 16, it is possible to efficiently capture the spatter 16.

近に集めてしまうこととなるからである。As shown in this embodiment (by arranging a small piece of a permanent magnet on the oil outflow side, that is, the outlet side of the oil suction boat, when the above small piece is arranged on the oil inflow side, that is, the population side of the oil suction boat), In comparison, spatter that has passed through the oil suction boat together with the lubricating oil 15a can be captured better.
This is because if it is disposed on the inlet side of the oil suction boat, the spatter accumulated at the bottom of the case 1 will be collected near the suction port 12 due to magnetic force.
