Résumé

In this study the simplified test model of a commercial reciprocating compressor for an automotive air-conditioner is designed to investigate the velocity distributions of the discharge flow from the suction valve using PIV (Particle Image Velocimetry) technique and to measure the displacement of the valve. The displacement of the conventional valve in the test model is observed using the high speed video camera and is also measured using a strain gauge. On the other hand the velocity distributions around the suction valve are measured using PIV and the relation between the velocity distributions and the movement of the valve is investigated. Furthermore the new valve with the shape improved from the conventional valve is designed and the results of the flow visualization and the measurement of the valve displacement for the new valve are compared with those of the conventional valve. The authors found that the vibration of the new valve can be suppressed 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 valve is discussed from the results of the present flow analysis.
