Abstract
A two-stroke internal combustion engine having a seal assembly disposed between a piston and a running surface. The seal both lubricates and prevents exhaust of combustion gases. A first element, which ensures gas tightness, is received in a countersunk portion of the running surface. A second element, which ensures oil tightness, is partially embedded into the first element. A biasing element presses the second element against the first element so that the second and third elements are at least partially held within the first element.
