摘要：A rod wiper for disposition about the rod of a fluid actuator comprises anannular wiper element of relatively high durometer having a pair of axially spaced lipsengageable with the rod of the actuator, and an annular elastomeric element ofrelatively lower durometer disposed radially outwardly of said wiper element. Theelastomeric element is normally engaged with only the wiper element and with an axialwall of a rod housing. However, the elastomeric element is movable into engagementwith a radial wall of the rod housing in the presence of dirt and scale on the rod. The axialforce on the elastomeric element results in an increased bias of the lips of the wiperelement on the rod.
