Grease oil aspirator of enclosed type compressor

Abstract

The invention provides an engine oil suction device of a hermetic compressor, which comprises the following parts: a sleeve of a pumping chamber to conduct engine oil pumping operation inside; a pumping roller which is arranged opposite to an eccentric position of the rotating center of a rotational axis which rotates through a motor part, provided with at least one side contacted with the inner face of the pumping chamber and slides into a fixed round track; vanes which is raised towards the inside of the pumping chamber, supported through flexible assemblies and provided with the front end contacted with the pumping roller, and divides the internal space of the pumping chamber; an engine oil path generation device with a path which leads engine oil to flow to the inside of the pumping chamber and a path which conveys the engine oil discharged from the pumping chamber to an engine oil channel of the rotational axis. The invention can pump and supply the engine oil for executing operations of cooling and lubricating more smoothly, thereby improving the operating reliability of the compressor.

Description

technical field [0001] The invention relates to an oil suction device of a hermetic compressor. Background technique [0002] Such as figure 1 As shown, the casing 1 constitutes the appearance of the scroll compressor, and a closed space is formed inside the casing 1 . The casing 1 is composed of an upper cover 1a, an outer frame unit 1b, and a lower cover 1c, and a suction pipe 2 and a discharge pipe 3 are attached thereto. Wherein, the above-mentioned suction pipe 2 penetrates the above-mentioned casing 1 and sucks the working fluid from the outside; the above-mentioned discharge pipe 3 is used for discharging the compressed working fluid. In addition, an oil storage portion 1d for storing engine oil is formed on the lower cover 1c of the housing 1 . [0003] A motor unit 4 is attached to the inside of the casing 1, and the motor unit 4 includes a stator 4a and a rotor 4b. Wherein, the above-mentioned stator 4a is fixedly arranged inside the above-mentioned casing 1; t...

Problems solved by technology

But, speaking from its structure, will not be close to the inner surface of above-mentioned suction cavity 16 exactly

As a result, the engine oil in the suction chamber 16 itself will leak to other areas, and a relatively small amount of engine oil will be sent to the above-mentioned engine oil flow path 5b, so that the engine oil cannot be supplied smoothly.
