Claims

[Scope of Claim for Utility Model Registration] (1) A plurality of cylinders arranged one above the other in the axial direction through partition plates, discharge valves that open and close discharge ports in the valve chambers of these cylinders, and opening and closing strokes of the discharge valves. In a multi-cylinder rotary compressor equipped with a discharge valve mechanism each having a regulating cylindrical valve holder, the partition plate has a communication hole that allows the insides of the valve holders of the cylinders located on both sides of the partition plate to communicate with each other. A multi-cylinder rotary compressor, characterized in that the space formed between the valve chamber wall of each cylinder and the outer peripheral wall of the valve holder is disconnected from communication by the partition plate. (2) The multi-cylinder rotary compressor according to claim 1, wherein the partition plate has a communication hole formed coaxially with the valve holders and having a hole diameter smaller than the outer diameter of these valve holders. . (3) The partition plate has a communicating hole coaxially formed with the valve holders located on both sides of the partition plate, and the opposing ends of the valve holders are fitted into the communicating holes.Request for Utility Model Registration. A multi-cylinder rotary compressor according to item 1.
