Benefits of technology

[0009]The present invention has been made in order to solve the above problems. It is an aspect of the invention to provide a rotary compressor capable of preventing, to the maximum extent possible, oil within the compressor from being discharged toward a refrigerant gas discharge port.

Problems solved by technology

However, the above described rotary compressor has a problem in that the amount of oil gathered in the compressor may be gradually reduced as time passes.
If the amount of oil within the compressor is reduced, it is difficult to achieve efficient lubrication and cooling of the compression device and drive device of the compressor and consequently, the compressor may suffer from many problems, for example, overheating, malfunction, and performance degradation.
Furthermore, the oil discharged through the discharge port along with the refrigerant gas may have a risk of forming an oil film at an inner surface of a heat exchanger or pipe included in a cooling system employing the compressor.
This results in a degradation in the efficiency of heat exchange and consequently, a degradation in the performance of the cooling system.

Abstract

A rotary compressor for preventing, to the maximum extent possible, oil within the compressor from being discharged to a gas discharge port. The rotary compressor includes a drive device and a compression device which are mounted in a hermetic container. The hermetic container includes an upper cover formed with a gas discharge port. The rotary compressor includes a scroll chamber defined in an inner surface of the upper cover around the discharge port, to separate oil from gas to be discharged, and a discharge guiding member installed inside the upper cover, to guide the gas, discharged from the hermetic container, into the scroll chamber and to guide the gas, having passed through the scroll chamber, to the discharge port.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Applications No. 2006-0107236 and No. 2006-107235, filed on Nov. 1, 2006 in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a rotary compressor, and, more particularly, to a rotary compressor capable of preventing, to the maximum extent possible, oil within the compressor from being discharged toward a refrigerant gas discharge port.[0004]2. Description of the Related Art[0005]Korean Patent Laid-open Publication No 10-2004-0023069 (published on Mar. 18, 2004) discloses a rotary compressor in which an oil flow path is formed in a rotating shaft, to supply oil gathered in a bottom region of a hermetic container to a compression device during operation of the compressor.[0006]The oil flow path includes an upright flow path perforated from a...
