In the present study the simplified test model of the commercial reciprocating compressor for an automotive air-conditioner is used to measure the displacement of the suction valves using a strain gauge and to investigate the velocity distributions of the discharge flow from the valves using PIV(Particle Image Velocimetry) technique. The new suction valves with the shape improved from the conventional valve are developed and the results of the measurement of the valve displacement for the new valves are compared with those of the conventional valve. It is found that the vibration for one of the new valves can be suppressed extremely compared with the conventional one from the experiment using both the present test model and the commercial reciprocating compressor. The reason of the vibration-reduction for the new suction valve is discussed from the results of the measurement of the displacement of the valve and the flow analysis. The design guide of the suction valve to prevent the vibration is presented in the study.
