摘要： An oil seal protector for rotary engines is provided to prevent deleterious combustion gases from damaging the oil sealing assemblies provided on each side of the engine rotor. The sealing assemblies include an O-ring and the protective device comprises annular grooves which extend completely about the sealing assembly on each side of the rotor and which are located radially outwardly from such sealing assemblies. A seal ring is fitted within each of the annular grooves of the protective device and spring means are provided for urging the ring against the sides of the engine housing.

摘要： A paint composition is provided, which comprises a copolymer comprising the following constitutional units (A), (B), and (C) as essential components: (A) a (meth)acrylate monomer unit having a straight-chain, branched-chain, or cyclic alkyl group; (B) at least one monomer unit selected from the group consisting of a monomer unit having an unsaturated double bond and a hydroxyalkyl group, a monomer unit having an unsaturated double bond and an epoxy group, and a monomer unit having an unsaturated double bond and an alkoxysilyl group; and (C) a monomer unit having an unsaturated double bond and a maleimide group. The paint composition is excellent in weatherability and coating gloss. The composition may be contained in an organic solvent such as cyclic ethers, aromatic hydrocarbons, esters, and ketones. The organic solvent may be one that comprises 40% or more of a saturated hydrocarbon. In this case, it is preferred that a (meth)acrylic ester monomer having an alkyl group of 8 to 20 carbon atoms accounts for 5 to 50% by weight of the total amount of the constitutional units of the copolymer.

摘要： An oil seal assembly is provided for a rotary engine in which an annular groove is formed in the side of the engine rotor with an oil seal ring being fitted within said annular groove. The oil seal ring is pressed against the side wall of the engine housing by annular spring means, and detent means are inserted between the ends of the annular spring means, the detent means being engaged in recesses carved in the innermost wall of the oil seal ring and in the bottom wall of the annular groove of the rotor to restrain relative motion therebetween during rotation of the rotor.
