Abstract

Ifølge oppfinnelsen er det frembrakt et støtforsterkende apparat som omfatter et stort sett rørformet innvendig element (10), et stort sett rørformet utvendig element (12) som er aksialt bevegelig i forhold til det innvendige element (10), en primær energilagringsanordning (50) som er innrettet til å lagre energi når det innvendige element (10) beveges enten i en første eller en andre aksial retning i forhold til det utvendige element (12), og en sekundær energilagringsanordning (48) som er innrettet til å lagre energi når det innvendige element (10) beveges i en første aksial retning i forhold til det utvendige element (12). Den primære energilagringsanordning (50) kan omfatte en primær forspenningsanordning. Den sekundære energilagringsanordning kan omfatte en sekundær forspenningsanordning. Den primære og/eller den sekundære forspenningsanordning kan være et fjærorgan valgt blant tallerkenfjærer, spiralfjærer, væske- og gassfjærer. Det støtforsterkende apparat omfatter fortrinnsvis rørformete elementer som har dobbeltskuldrete høytorsjonssammenkoplinger (J1, J2, J3).
