Abstract
A foam control device includes a first member coupled to an oil reservoir of a compressor and a second member to prevent foam from flowing into an interior section of the compressor. when a shaft of the compressor rotates. The second member controls a position of the first member based on at least one condition which, for example, may include an amount of oil in the reservoir, an environmental condition, or the type of oil or refrigerant used. According to one embodiment, the first member includes a plate containing one or more apertures that allow oil, suctioned from the reservoir, to pass back into the reservoir when the compressor shaft rotates.
Claims31
A scroll compressor, comprising:
- a container to hold a predetermined amount of oil;
- a shaft to transmit rotational force to a rotating scroll, the rotating scroll engaging a fixing scroll to form one or more pressure chambers for compressing refrigerant gas, the shaft further suctioning oil from the container to lubricate one or more parts of the compressor;
- and
- a member to prevent foam from flowing into one or more interior portions of the scroll compressor. when the shaft rotates.
