用于摆动式压缩机,减少唇环磨损并防止压缩空气泄漏。
专利摘要
唇形环附接到活塞,以便相对于活塞在圆周方向上可旋转,并且在活塞的环附接槽和唇形环的附接部分之间设置密封部分。在吸入冲程期间,唇形环可在活塞的圆周方向上旋转,从而使磨损分布在唇形环的唇部分的整个周边上。在压缩冲程期间,可通过设置在环附接槽和唇形环之间的密封部分防止空气从压缩腔泄漏。
Original abstractA lip ring is attached to a piston so as to be rotatable relative to the piston in a circumferential direction, and a seal portion is provided between a ring attachment groove of the piston and an attachment portion of the lip ring. During a suction stroke, the lip ring can be rotated in a circumferential direction of the piston, thus distributing wear around the entire periphery of a lip portion of the lip ring. During a compression stroke, leakage of air from a compression chamber can be prevented by means of the seal portion provided between the ring attachment groove and the lip ring.
