Document Type and Number:
WIPO Patent Application WO/2023/191265
Kind Code:
A1
Abstract:
A discharge unit of a reciprocating compressor according to an embodiment of the present specification may include a pulsation reducing member located inside a discharge muffler, wherein the pulsation reducing member may include a partition wall member and/or an extension part. The partition wall member may include a first partition wall located on the inner surface of the bottom portion of a muffler cover and protruding toward a muffler body, and a second partition wall located on the inner surface of the bottom portion of the muffler body and protruding toward the muffler cover. In addition, the extension part may be formed as a part of a discharge hose or may be a part manufactured separately from and connected to the discharge hose. The extension part may have a first inlet hole in an end thereof. In the reciprocating compressor having this configuration, pulsation caused by a high-pressure refrigerant discharged periodically can be effectively reduced by varying at least one factor among the number of partition walls provided in the internal space of the discharge muffler, the distance between the partition walls, the length in the vertical direction of the partition walls, the position of the partition walls, and the length in the vertical direction of a flow path, or by adjusting the height, direction, and the like of the first inlet hole formed in the end of the extension part in various ways.
