Sealing systems consisting of stationary seat and rotating seal surfaces are considered. The seal and seat surfaces may be in surface contact or in line contact. The geometry of different types of seal-seat surfaces is discussed: (a) with surface contact between conical and spherical surfaces and surfaces of revolution, (b) with line contact of a surface of revolution and a conical surface. A new method for synthesis of conjugated surfaces for sealing systems is proposed. The method is based on specific applications of the general theory of enveloped surfaces. Seal and seat surfaces synthesized by this method are in surface or line contact at the closed position and do not interfere with each other at any open position. Relations between design parameters of sealing systems to meet these requirements are developed. The method presented uses general assumptions and can be applied for various types of seal-seat surfaces. Examples of synthesis of seal-seat surfaces are provided.
