It is supported at the inner upper position of the sealed casing (1) as shown in a) via a fixed scroll (21) and a frame (3) fixed inside the revolving casing (1). A motor (4) is arranged at a lower position, and a drive shaft (5) connected to the motor (4) is connected to the frame (3).
While freely supporting rotation through a plurality of bearings (6),
A transmission mechanism C is disposed at the upper end of the drive shaft (5) and drives the revolving scroll (22) of the compression element (2) to revolve relative to the fixed scroll (21) as the drive shaft (5) rotates.

As the pump element (7) rotates, the lubricating oil stored in the oil reservoir (1a) is pumped up and supplied to the bearing (6) and other lubricated parts from the oil supply passage (5a). I'm doing my best.

:'b-f-mjl'P As shown in detail in the bottom oil sump (1a) of the casing (1), the oil sump (1a)
) A cylindrical filter (8) having a large number of pores is attached in a rod-like manner to the oil sump (1a) at a position facing the lower end of the drive shaft (5) which is inserted into the oil sump (1a). (8) surrounds the outer periphery of the lower end of the drive shaft (5) and connects the upper end of the filter (8) with the drive under the surface of the lubricating oil stored in the oil sump (1a). It is attached to the oil sump (la) so that a predetermined opening (8a) is formed between it and the shaft (5).

路（５ａ）への給油が保障されるのである。By doing so, when the drive shaft (5) is rotationally driven,
Since the filter (8) does not follow the rotation and the lubricating oil in the oil sump (1a) is not agitated by the filter (8), the oil level in the oil sump (1a) is always approximately equal to This ensures that the drive shaft (5) is kept at a constant height and that the drive shaft (5) is supplied with oil to the oil supply passage (5a).

The lubricating oil in the oil reservoir (1a) is introduced into the interior from a) and is supplied to the oil supply passage (6a) of the drive shaft (5).

防止できるのである。In this case, the lubricating oil in the oil reservoir (1a) is supplied from the opening (8a) to the oil supply passage (5a) of the drive shaft (5) without being passed through the filter (8). However, unlike in the past, lubricating oil is not supplied to the oil supply passage (5a) due to clogging of the filter (8), and the worst case scenario in which lubrication failure occurs in each lubricated part can be prevented. be.

Since the cylindrical filter (8) is enclosed and has its upper end opened below the oil surface of the oil sump (1a), it is installed as if it were a conventional filter.
The lubricating oil stored in the oil sump (1a) passes through the filter (8).
) causes the oil level to fluctuate, and the drive shaft (5
) can prevent a situation in which the amount of oil supplied to the oil supply passage (5a) decreases, and even if the filter (8) becomes clogged, the amount of oil supplied to the oil supply passage (5a) can be prevented. The predetermined amount of oil supplied to the passageway (5a) can be ensured, and it has become possible to reliably prevent the worst-case scenario in which each lubricated portion suffers from poor lubrication.
