DISPOSITIVO AMORTIGUADOR DE RETROCESO, ESPECIALMENTE PARA ARMAS AUTOMATICAS DE TIRO RAPIDO

摘要

The recoil cushioning device comprises a recoiling member guided in a fixed member with cushioning means comprising a constant volume chamber placed between two diaphragms, said chamber being subdivided into three areas separated by constrictions. A recovery spring is compressed during recoil. When the recoil amplitude is adequate a bearing surface is applied against a cushion, which increases rigidity.
