ABSTRACT:
A seal mountable between a piston-like element and a cylinder-like element, one of which is formed with a groove opening toward the other, has a supple annular core with an inner periphery and an outer periphery spaced radially therefrom. One of these peripheries lies in the base of the groove and the other periphery is turned radially toward the other element. A central contact ring is compressed radially between the other periphery and the other element and at least one rigid guide sleeve has an end region at least partially surrounding the core and formed with an end face axially engageable with the contact ring. The sleeve lies between the elements. The annular core is elastomeric, the contact ring is formed of readily deformable material having a very low coefficient of friction, and the guide sleeve is formed of a very stiff and durable synthetic resin.
