たのである。(Problems to be solved by the invention) By the way, in the space (S1) where the gas vent hole (A) is opened, a discharge port (D) of the compressed gas compressed by the compression element (CP) is opened. Therefore, the gas discharged from the discharge port (D) interferes with the lubricating oil discharged from the gas vent hole (A) to the space (S1), and this lubricating oil is discharged together with the discharged gas. It is lifted to the upper space (S2) through the air gap (G) of the motor (M), etc., and particularly when high speed rotation is performed during inverter operation, the lower side is removed from the gas vent hole (A). Space (S1)
Since the amount of oil discharged to the upper part becomes large, the amount of oil lifted to the upper space (S2) by the discharge gas also becomes large, and the amount of oil in the oil reservoir becomes small, causing a so-called oil rising problem. Of.

とを特徴とする密閉形圧縮機。A motor (2) and a compression element (3) are installed in a closed casing (1), and a discharge port (2) for releasing compressed gas is provided at the top of the compression element (3) on the opposite side of the motor (2). 35) and a bearing (5) that supports the drive shaft (4) of the motor (2), and an oil supply passage (41) is provided in the shaft center of the drive shaft (4). Bottom oil sump (1
(a) is a hermetic compressor whose other end is opened between the motor (2) and the compression element (3) through a gas vent hole (43), wherein the motor (2) and the compression element (3)
Between the discharge port (35) and the opening position of the discharge port (35) in the radial direction, the oil discharge passage opening space (6A) where the gas vent hole (43) is opened and the discharge port (35) are opened. A hermetic compressor characterized in that a partition body (9) for partitioning the gas path open space (6B) is interposed.
