<p>PROBLEM TO BE SOLVED: To provide a gas compressor which reduces the number of components thereby reducing the costs while maintaining a function of a non-return valve.SOLUTION: A non-return valve 30 which blocks reverse flow of a refrigerant gas from a suction chamber 16 to a suction port 7 side includes: a valve body 31 disposed in a substantially cylindrical guide case 33 integrally formed with a suction chamber 16 side end surface (a front side block 14) of a compressor body 5, the valve body 31 capable of moving along a longitudinal direction of the guide case 33; and a coil shaped spring 32 which biases the valve body 31. An outer periphery part 31b of the valve body 31 is biased to a valve seating surface 7a of the suction port 7, which is formed around a lower end of an opening facing the interior of the front head 3, by a biasing force generated by the spring 32.</p> |
