Compressor having pressure controlled for improving oil distribution

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;
• 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 the compression element is disposed above the driving element, and oil is supplied to the compression element from an oil reservoir in a bottom part of the sealed container by an oil pump, and
• wherein the fluid is discharged from the discharge port into the sealed container, and a pressure on a side of the other surface of the compression member is set to a value which is higher than that of a pressure of the fluid sucked into the suction port and which is lower than that of a pressure in the sealed container.
