<p>PURPOSE:To decrease the pulsation of a pressure and reduce the vibration as well as the noise of the compressor by a method wherein flow resistances due to suction paths or the like to respective cylinders of the compressor are rendered to be substantially equal. CONSTITUTION:Refrigerant medium gas is induced into the cylinder 6a from the suction port 26 in a valve plate 9 via a suction valve 27 formed on a suction valve plate 22. The hights of the stoppers of the suction valves 27 are different for each cylinders 6a and the suction valve for a longer suction path is formed so as to be larger in the amount 1 of the valve lift, therefore, valiabilities in the flow resistances due to the different lengths of the suction paths are cancelled by the difference in the flow resistance due to the difference of the amount 1 of the valve lift and the flow resistances for each cylinders 6a become substantially equal thereby enabling to decrease the pulsation of the pressure of the compressor.</p> |
