Abstract

본 발명은 스크롤 압축기내에 설치되는 선회스크롤과 고정스크롤의 랩 선단부에 열팽창계수가 큰 재질의 지지부재와 내마모성이 양호한 재질의 팁시일재를 상대 스크롤의 경판에 밀착시키기 위해 탄성체와 같은 부품을 사용하는 종재 장치에 비해 가공 및 조립이 용이해질수 있게 한 스크롤 압축기의 팁실링 장치를 제공하기 위한 것이다.The present invention uses a component such as an elastic body to closely adhere the support member made of a material having a high coefficient of thermal expansion and the tip seal member made of a good wear resistance to the hard plate of the counter scroll at the lap end of the swing scroll and the fixed scroll installed in the scroll compressor. It is an object of the present invention to provide a tip sealing device for a scroll compressor that can be easily processed and assembled as compared to the finishing device.

본 발명은 스크롤의 랩(22)선단부에 홈을 형성하여 이홈에 지지부재(30)를 삽입 고정하고 지지부재에 형성된 오목홈부에 팁시일부재(31)를 결합하여 지지부재의 열팽창력에 의해 열팽창력에 의해 팁시일부재가 상대스크롤의 경판에 밀찰되게 하여서 된 스크롤 압축기의 팁실링장치이다.The present invention forms a groove at the tip of the wrap (22) of the scroll to insert and fix the support member (30) in this groove, and to couple the tip seal member (31) to the concave groove formed in the support member by thermal expansion force of the support member It is a tip sealing device of a scroll compressor in which the tip seal member is pressed against the light plate of the counter scroll by the force.
