Compressor

A compressor comprising:

• a compression element comprising a cylinder in which a compression space is constituted;
• a suction port and a discharge port which communicate with the compression space in the cylinder;
• a support member which closes an opening of the cylinder;
• a rotary shaft which is rotatably supported by a bearing formed on the support member;
• a compression member whose one surface crossing an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and which is disposed in the cylinder to be rotated by the rotary shaft and which compresses a fluid sucked from the suction port to discharge the fluid via the discharge port;
• a vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member and which partitions the compression space in the cylinder into a low pressure chamber and a high pressure chamber;
• and
• a piston ring seal which is disposed on the rotary shaft disposed in a position corresponding to the bearing.

A compressor comprising:

• a driving element stored in a sealed container;
• and a compression element driven by a rotary shaft of the driving element,
• the compression element comprising:
• a cylinder in which a compression space is constituted;
• a suction port and a discharge port which communicate with the compression space in the cylinder;
• a compression member whose one surface crossing an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and which is rotatably disposed in the cylinder and which compresses a fluid sucked from the suction port to discharge the fluid from the discharge port into the compression space;
• and
• a vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member and which partitions the compression space in the cylinder into a low pressure chamber and a high pressure chamber,
• wherein a pressure of the compression member on the other surface side is set to a value which is lower than that of a pressure in the sealed container.
