PURPOSE: A structure of a gas channel of a reciprocating compressor is provided to prevent concentration of stress of a valve, and to prevent colliding noise and separation of the valve by dispersing refrigerant gas introduced into a compression space. CONSTITUTION: A piston(110) is joined to a mover of a reciprocating motor, inserted to a compression space of a cylinder to slide, has a suction channel(111) formed therein in moving direction thereof, and suction connecting ports(112) formed on an inside of the suction channel to penetrate a front end thereof and to be opened and closed by a suction valve(120). Magnet mounting grooves(113) are formed on a circumference of a front end side of the piston at regular intervals to allow magnets(M) to be laid therein at regular intervals so as to fix the suction valve. The suction channel is formed coaxially with the piston. The suction connecting ports are formed to be smaller than a diameter of the suction channel, and placed on a center of the suction channel. The suction valve is spirally formed, and has a fixed part(121) formed on a circumference thereof to be attached and fixed to the magnets laid in the piston; and an opening and closing part(122) formed on a center thereof.
