HERMETICALLY CLOSED TYPE ELECTRIC COMPRESSOR
Document Type and Number:
Japanese Patent JP2002098056
Kind Code:
A
Abstract:
To solve the problem of lowering the heat exchange rate of a refrigerating cycle due to a large quantity of refrigerator oil discharged to the refrigerating cycle from a discharge pipe in a conventional hermetically closed type electric compressor used for an air conditioner or a refrigerator.
Oil covers are provided on the upper and lower sides of a stator, and a porous filter is installed between the lower oil cover and a support part for supporting an auxiliary bearing. Discharged gas positively passes through the filter after passing through a space formed by the inner diameter of a closed container and a compressor component.
