PURPOSE: An inner pressure control valve of a compressor is provided to prevent melting of a sealing material and carbonization of oil by preventing gas of high temperature from flowing into a suction pressure area. CONSTITUTION: A suction port(71) is formed to circulate air to a discharge pressure area. A discharge port(72) is formed to circulate air to a suction pressure area. A valve main body(77) has a passage connecting the suction port with the discharge port. A sliding member(75) is installed at the valve main body, movable between a closed position shutting the passage and an open position opening the passage. An elastic member(74) is installed between the sliding member and the valve main body to place the sliding member at the closed position. A thermal reacting member(180) has a shape changeable according to a temperature. If the sliding member is placed at the open position, the thermal reacting member opens the passage in a low temperature while shutting the passage in high temperature. A support ball(75) is installed between the thermal reacting member and the sliding member.
