摘要 |
A scroll type compressor which includes a compression unit, a crankshaft having an oil passage therein, and an electric motor stator having an oil return hole. An oil pump feeds oil into the oil passage of the crankshaft, and an oil drain tube receives return oil from the compression unit and feeds the oil to the oil return hole of the electric motor stator. The drain oil tube advantageously includes an upper nonflexible drain opening which receives oil from the compression unit. The oil then passes through a nonflexible portion which includes a bend or bent portion, and then to a flexible portion which extends from the elbow into the oil return hole of the electric motor stator.
