Abstract: PROBLEM TO BE SOLVED: To prevent the excessive adherence of a reed valve, suppress the generation of noise and suppress an increase in motive power consumption caused by excessive compression, while reducing the number of precesses of a discharge valve and the number of parts to reduce a cost.
SOLUTION: Each opposite face of the reed valve 22 and a valve seat 21 has magnetism of homopolarity to lift the reed valve 22 from the valve seat 21 by using the bounce of the magnetism. When inverse pressure is generated between the valve seat 21 and the reed valve 22 that are closely adhered to each other by an air pressure difference that is created at a discharge valve chamber 15 side and higher than that of a discharge hole 13, and when the reed valve 22 is separated from the valve seat 21, the separation is facilitated by using the bounce of the magnetism to separate the reed valve 22 from the valve seat 21 without a delay in response and with less shock.

Abstract: PROBLEM TO BE SOLVED: To improve the reliability of an intake check valve which is arranged in an air intake passage of a gas compressor so as to prevent counterflow of gas when the operation is stopped, to decrease the number of components and to reduce the cost.
SOLUTION: Permanent magnets 34a, 31a having polarities which attract each other are attached to a seal section of a valve core 34 and a seal section of a stopper 31, respectively, so that the valve may be closed by the attraction force of the magnets 34a, 31a. When the operation of the gas compressor is stopped, the valve is closed by the attraction force of the magnets, and during operation of the gas compressor, the air suction force of the gas compressor overcomes the attraction force of the magnets so as to open the valve.
