| A compressor having a rotating member, which includes a drive shaft and a swash plate. A piston compresses gas and torsionally vibrates the rotating member. A damper is coupled to the shaft to reduce torsional vibrations of the rotating member. The natural frequency of the damper is substantially equal to that of the rotating member. The damper includes a metal pin coupled to the shaft, a weight coupled to the rotating member, and a rubberlike body arranged between the shaft and the weight. The pin functions as a spring acting in the direction of the torsional vibrations and has a spring constant that remains substantially the same within the operating temperature range of the compressor. The weight is vibrated torsionally with the rotating member by the pin to offset the torsional vibrations of the rotating member. The natural frequency of the damper is determined mainly by the mass of the weight and the spring constant of the pin. The rubberlike body absorbs the torsional vibrations of the rotating member and has a spring constant smaller than that of the pin such that the natural frequency of the damper is substantially unaffected by the rubberlike body. | ||||||
