FIELD: engines and pumps.
SUBSTANCE: cellular element 1 with case 2 and cellular structure 3 with multiple channels 4 composed by at least one partially shaped meta layer 5. Said metal layer forms joint points 6 to fix cellular structure 3. Cross-section 8 of said structure has radial zones 38, 39, 40 with joint points 6 arranged at different density therein. Note here that al least in one zone 1-20% of inner contact points 7 in said cross-section 8 form one joint point 6.
EFFECT: longer life, higher teat shock resistance and durability, better antivibration vibroacoustic performances.
