mechanical engineering; internal combustion engines. SUBSTANCE: invention is designed for timing systems of internal combustion engine. According to invention, bead limits free axial displacement of spool into bushing and maintains required microclearance between mating parts at initial stage of operation. thermocouple starts operating as temperature action increases at linear expansion of "bushing- spool" working pair to provided minimum clearance between these parts and prevent jamming. EFFECT: prevention of jamming of conical spool, preservation of compression in engine cylinder by stabilizing clearance between bushing and spool cone at combined operation of limiting bead and thermocoupled. 7 cl, 1 dwg
