VIBRATION ISOLATOR SPRING BY KOCHETOV Russian patent published in 2009 - IPC F16F1/32 F16F3/02 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering, instrument engineering and can be used for vibration insulation of process equipment. Vibration isolator contains case, flat annular resilient members connected to each other. Case is implemented in the form of cylinder course with cavity for fixation of external ring. Co-axial located cylindrical core is implemented with cavity for fixation of inner ring. Resilient spring member is implemented in the form of at least two resilient co-axial located rings - external and internal. Rings are rigidly connected to each other by means of at least two symmetrical resilient, diametrically located members with pass-through center groove, symmetrically located inside the member. Side surfaces of groove are conjugated by ends with diametrical surfaces, formed by reach-through holes, respectively located on external and internal rings.

EFFECT: it is achieved effectiveness increase of vibration insulation in resonant mode and simplification of structure and mounting.
