In a two-strok engine, two pistons (11a, 11b) are coupled together so that when there is a compression stroke in one cylinder (15a), there is a power stroke in the other cylinder (15b). The shaft (13) connecting said pistons (11a, 11b) is equipped with dynamic magnetic bearings (12) and contactless seals (14), such as labyrinth seals.
