Differential pressure sensor in a capacity control valve for a compressor

Abstract From the Canadian patent

This invention is directed to a useful improvement in a capacity control valve for use in a fluid compressor with a relatively high pressure HP and a relatively low pressure LP for changing the operational characteristics thereof by using the relatively high pressure HP taking into consideration such an observation that an increased pressure losses of the refrigerant as generated from an increased flow rate thereof and the thermal load on the car cooler would occasionally occur on the part of the relatively high pressure HP during the operation. This improvement is as, summarized in brief, concerned with a capacity control valve of the type operative to take the intermediate pressure AP for …
