| Zusammenfassung: | The invention is a piston for compressor with variable displacement in car air conditioning system, the piston rotates with the driving axis, and it moves reciprocally between the upper and subjacent dead centers through the tilted plate of driving shaft in the crank cavity, the character lies in: the piston has several oil pits on the outer surface contacting with the inner surface of cylinder hole.
一种汽车空调系统中可变排量压缩机的活塞，该活塞(7)随驱动轴(2)的旋转，通过安装在曲轴腔(15)内的驱动轴(2)上的斜盘(6)，在汽缸孔内从上死点到下死点之间往复运动，其特征在于：该活塞(7)在与汽缸孔内周面滑动接触的外周面上均匀设置多个油坑(71)。本发明活塞外周面油坑能够使斜盘与活塞的连接部件等得到有效的润滑，并能有效地降低活塞外周面与汽缸孔内周面之间的滑动阻力，大幅度抑制动力损失。 |
