摘要： In relation to a vane type gas compressor in which a cylinder block, a front side block, a rear side block, a rotor and vanes are made of aluminum alloys, and a rotor shaft which is supported between bearing portions of the both side blocks in a manner freely capable of rotation is made of an iron series metal. It is intended that a refrigerant which does not destroy the ozone layer is used, and no cohesion is caused at the bearing portions even when the bearing portions are in a no-lubrication state. HFC-134a (1,1,1,2-tetrafluoroethane; CH₂FCF₃) containing no chlorine in its component is used as the refrigerant. Bushes and which are made of cast iron subjected to the phosphate coating treatment are provided at boss portions of the both side blocks.

摘要翻译： 关于其中气缸体，前侧挡块，后侧挡块，转子和叶片由铝合金制成的叶片式气体压缩机，以及转子轴，其被支撑在两侧块的轴承部分之间 能够自由旋转的方式由铁系列金属制成。 意图是使用不破坏臭氧层的制冷剂，即使在轴承部处于非润滑状态下也不会在轴承部分产生内聚。 使用其成分中不含氯的HFC-134a（1,1,1,2-四氟乙烷; CH 2 FCF 3）作为制冷剂。 在两侧块的凸台部设置有经过磷酸盐处理的铸铁制成的衬套。
