Summary

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. This paper is focused on the effects of shape of the suction valve on the vibration reduction. First, the size of the conventional valve hole and the width of the tip of the conventional valve are changed and seven new valves are manufactured to reduce the vibration of the valve. Consequently, it is found that one of the new valves is the most effective for vibration reduction. Next, the influence of the natural frequency on vibration reduction is investigated using one of the new valves by changing the material and the thickness of the valve. Finally, the reason for the vibration reduction for one of the new valve is discussed from the results of the flow analysis around the valve. The vibration reduction for one of the new valves is confirmed by measurement of the displacement of the valve in the reciprocating compressor for the automotive air conditioner.
