Title:
COMPRESSOR INCLUDING ROUNDED PORTION FORMED AROUND DISCHARGE PORT THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/236096
Kind Code:
A1
Abstract:
The present invention relates to a compressor which includes: a rounded portion formed around a discharge port thereof; a cylinder from which a diaphragm has been removed for convenience of shaping the rounded portion; and a cylinder cover which can be coupled to the cylinder. The compressor includes a valve groove formed to be recessed toward the inside of the cylinder, and a discharge valve installed in the valve groove so as to open or close the discharge port. The valve groove may be formed to have one side in contact with the lower surface of a main side block and have the other side folded on the upper surface of a sub-side block. Additionally, the valve groove includes a rounded portion formed to protrude from one surface thereof and surround the outer peripheral surface of the discharge port and thus can reduce a contact area between the discharge port and the discharge valve.
