する回転式ヘリウム圧縮機。[Claims for Utility Model Registration] A rotary piston 3 is eccentrically and rotatably housed in a cylinder 2, and both end surfaces of the cylinder 2 are closed by head covers 4 and 5, so that a compression chamber 8 is formed in the cylinder 2. Helium gas is introduced into the compression chamber 8, cooling oil is supplied into the helium gas, and the rotation of the rotary piston 3 compresses and discharges the helium gas. In the compressor, one of the head covers 4 and 5 is provided with a gas discharge port 21 that communicates the compression chamber 8 with the outside and discharges helium gas. An oil discharge port 22 that communicates the compression chamber 8 with the outside and discharges oil on the trailing side in the rotational direction.
On the other hand, a discharge valve 23 for opening and closing the gas discharge port 21 and the oil discharge port 22 is installed on the outside of the head cover 4 at the trailing end in the rotational direction of the rotary piston 3. A rotary helium compressor characterized in that an oil discharge port 22 is positioned so as to open before oil compression.
