Abstract
For manufacturing a seal between two machine parts (10, 11) which together enclose a space (14) in which, at least at times, high pressure and/or high temperature prevail, sealing means which contain a curable composition (30) are arranged between the two machine parts (10, 11). The curable composition (30) is applied directly onto one or both machine parts (10, 11) in liquid form at least in the area which does not directly adjoin the space (14) in which, at least at times, high temperature and/or high pressure prevails. The two machine parts are built in before the curing of composition (30). A sealing ring can be inserted between the two machine parts (10, 11) directly around the edge of the high pressure and high temperature space (14) or that edge can be slightly raised and the curable composition (30) can be used for sealing outside this area. The sealing ring can lie in a recess of a seal surface (12) of the peripheral wall of the chamber (14), the recess being dimensioned so that the pressure required for the seal is exerted on the sealing ring in the assembled state of the two machine parts (10, 11). The two machine parts can be the elngine block (10) and the cylinder head (11) of a piston engine.
