KASHIGIN'S SEPARATOR OF TWO MEDIA (VERSIONS) Russian patent published in 2014 - IPC F16K41/10 F16J15/36 F04B45/02 

FIELD: process engineering.

SUBSTANCE: set of invention relates to machine building and can be used in a wide range of equipment incorporating bellows. Proposed structure comprises bellows with crimps that have sections on vertices and recesses and lots there between. One end of said bellows can displace axially and is secured in the case or on the shaft while its opposite end is fixed on the shaft or in the case. Split spring is fitted above or inside said bellows. Reinforcing small split spring rings with interlock, ring cross-section being defined by bellows crimp shape. Note that said ring is made from material stronger than that of bellows. Invention covers two versions of the device for separation of two media.

EFFECT: expanded range of applications, axial stiffness, higher reliability and reparability.
