The discharge valve impact force on the valve retainer and valve plate play a critical role on the NVH characteristics of the wobble plate compressor. Another contributing factor to compressor NVH is in-cylinder bore over-pressure. In order to improve the NVH characteristics, a reduction in the valve impact forces and in-cylinder over-pressure is essential. The focus of this paper will be a new valve plate assembly change utilizing a unique design arrangement. This new design change significantly improved compressor NVH characteristics due to reduction in the the valve impact force as well as in-cylinder over-pressure. A slight reduction in compressor cooling capacity was observed. Research efforts are continuing to overcome this reduction.
