FIELD: space material science.
SUBSTANCE: invention relates to process equipment intended for growing chalcogenide crystals in microgravity conditions – an important direction in space material science. Axial compensator of spring-piston type contains unloaded compensating element made in the form of helical cylindrical graphite spring 1 arranged between two cylindrical pistons 2 from quartz glass so that cylindrical rods 3 of pistons 2 are centering elements for spring 1.
EFFECT: design of the compensator provides for repeated actuation to compensate loads arising at launch of the carrier rocket, with increase of volume of loading in ampoules at its melting or dissolution in melt, at landing of descent device with ampoules containing grown crystals.
