摘要： A refrigerant material transfer adapter in the form of an instrument of semi rigid yet flexible plastic having a side tube projection that fits on an aerosol can valve stem of the type that opens the can valve for release of contents when the valve stem is sidewise angle deflected. The adapter has an outlet end with an opening shaped to fit on and over the low pressure suction side valve fitting of a refrigeration system. A center projection within the outlet end opening engages the valve stem of the refrigeration system suction side valve fitting so that when the adapter is pushed toward the refrigeration valve fitting the refrigeration system valve is opened. This is accomplished generally using both hands or with the thumb of the hand holding the aerosol can pressing against the back end of the adapter. With the adapter so positioned and pushed the hand holding the aerosol can moves the can so the valve stem inserted in the adapter side tube is deflected to a sidewise angle relative to the can sufficiently to open the can valve so that refrigeration gases and/or fluids are aerosol propelled from the can to the refrigeration system. This contributes a factor of safety in that the can valve is opened only after the refrigeration system valve is opened.

摘要翻译： 具有半刚性但柔性塑料的仪器形式的制冷剂材料转移适配器，其具有装配在气雾罐上的侧管突出部，该阀杆可在阀杆侧向角度偏转时打开罐阀以释放内容物 。 适配器具有出口端，该出口端具有适于安装在制冷系统的低压吸入侧阀配件上和上方的开口。 出口端开口内的中心突起与制冷系统吸入侧阀配件的阀杆接合，使得当适配器被推向制冷阀配件时，制冷系统阀打开。 这通常使用双手或用手的拇指握住气溶胶可压紧适配器的后端来完成。 如果适配器被如此定位并且被推动，则握住气溶胶的手可以移动罐，使得插入适配器侧管中的阀杆相对于罐足够地偏转到侧向角度以打开罐阀，使得制冷气体和/或流体 是从罐向制冷系统推进的气溶胶。 这导致安全性的因素是仅在制冷系统阀打开之后才能打开罐阀。
