In rotary piston engines including apex seals each comprising a main body constituting a substantial part of the seal, an end piece disposed in abutting relationship to an end of the main body through slanted cam surfaces which serve to force the end piece axially outwardly to engage with the inner surface of the side housing when the end piece is resiliently biased radially outwardly by spring means, the method of assembling the apex seals in the rotary piston engine, which comprises providing a projection of consumable material between the main body of each seal and the spring means so as to retain the spring means preventing the end piece from being displaced over the end face of the center housing, the consumable material being of such a type that dissipates under heat produced during engine operation. |
