    摘要: A rotary piston of a rotary piston internal combustion engine has radially and inner and outer annular seals carried within grooves of the rotary piston thrust surface axially facing the engine casing sidewall with the axial end face of the oil seal tapering radially outwards relative to the engine sidewall and forming lip angles between the tapered end wall of the seal such that the lip angle for the outer seal is between 1.degree. and 3.degree., the lip angle for the inner seal is between 3.degree. and 5.degree., and the spring biasing force acting on the radially outer seal is less than that acting on the radially inner seal. Preferably, an oil removal bore is formed in the land portion between the grooves for return of the oil delivered thereto by action of the oil seal to the oil pan of the engine.

    摘要: 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.
