Abstract

Inventia se refera la un amortizor care preia fortele datorate aparitiei socurilor prin intermediul unui elastomer si care poate fi folosit, de exemplu pentru amortizarea socurilor care apar în timpul deplasarii unui vehicul pe sine sau a unui autocamion, sau în cel al functionarii unei macarale. Amortizorul, conform inventiei, cuprinde o tija de care este fixat un piston care delimiteaza intr-un spatiu al unui corp cilindric niste camere inferioara si superioara, antre piston si corp existand un spatiu inelar prin care un elastomer poate curge din camera inferioara în camera superioara sau invers. Pistonul este strabatut de niste canale longitudinale prin care o degajare cilindrica frontala închisa spre în jos prevazuta în piston poate comunica cu camera superioara aceasta comunicare fiind închisa dupa ce pistonul si tija s-au deplasat spre în jos sau spre în sus pe o anumita distantade catre o piesa inelara mobila, avand un orificiu central, retinuta în degajare de catre un inel limitator filetat la exterior în scopul realizarii îmbinarii lui cu un capat frontal al pistonului, astfel ca piesa se poate deplasa între o suprafata superioara a inelului limitator si o suprafata frontala a pistonului care delimiteaza superior degajarea si care este îndreptata spre capatul inferior închis al corpului.
