Description

本实用新型提供了一种新型活塞,装入气缸或油缸中,是气动或液压系统中的重要零部件。
现有的小气缸活塞,用橡胶件制造,其不足之处在于抗热涨冷缩性差,密封性差,强度低,弹性差,耐磨性、耐油性亦较差。
本实用新型的目的在于克服上述不足之处而提供一种新型活塞。
本实用新型的目的是这样实现的:活塞为圆柱形,中央有孔,外圆柱面上的母线为曲线,端面为向内凹的曲面,有两个密封唇,本活塞既起活塞作用又起密封件作用,用同一种材料制造。
本实用新型的优点在于结构新颖,集活塞与密封件于一体,用同一种材料制造成整体,抗热涨冷缩性好,密封性好,耐油、耐蚀、耐磨性均好。
图1为活塞剖视图。
结合附图对本实用新型作进一步的说明。
活塞为圆柱形,中央有孔,外圆柱面上的母线为曲线,端面为向内凹的曲面,有两个密封唇,本活塞装入气缸或油缸中,既起活塞作用又起密封作用,活塞与密封件连为一体,用聚氨酯制造。

Claims (2)

1、一种活塞,圆柱形,中央有孔,其特征在于它的外圆柱面上的母线为曲线,端面为向内凹的曲面,有两个密封唇。
2、根据权利要求1所述的活塞,其特征在于它为用同一种材料制造的整体结构。
