Abstract

An oil supply device for a hermetic compressor comprises: a crankshaft connected with a motor so as to rotate together with it and having a lubricating oil flow passage inside; a sleeve connected with the lower part of the crankshaft so as to become a One body, rotating together; an oil absorbing member arranged to maintain a uniform interval with the inner peripheral surface of the sleeve for oil absorption; and a supporting device for supporting the oil absorbing member to slide, the supporting device is connected between the sleeve and the oil absorbing member in order to maintain a static state. The oil-absorbing member is supported in such a way that it cannot rotate around the center of rotation of the sleeve, so that it is not affected by the vibration of the operating compressor, and a uniform gap is maintained between the inner peripheral surface of the sleeve and the oil-absorbing member, thereby Improve the reliability of fuel supply.

Description

Technical field [0001] The invention relates to an oil supply device for a hermetic compressor, and more specifically, to an oil supply device for a hermetic compressor that can increase the oil supply and improve the lubricating performance. Background technique [0002] Generally, a hermetic compressor is used as a device for supplying compressed fluid and is mainly used in cooling systems, such as refrigerators, air conditioners, and so on. [0003] figure 1 It is a cross-sectional view of a hermetic compressor in the prior art. [0004] See figure 1 , The hermetic compressor in the prior art includes the following components: a sealed housing 1 forming a sealed space inside; an electric motor 3 installed inside the sealed housing 1 to provide driving power; The compression device 30 that compresses the fluid by the driving power of 3; and the oil supply device 20 that supplies lubricating oil to the inside of the sealed housing 1 to complete the lubrication and cooling fun...
