Abstract

L'innovazione in oggetto รจ stata concepita al fine di migliorare i sistemi di alimentazione della pressione dell'olio, che determina lo spostamento degli sfili costituenti un cilindro telescopico oleodinamico.Infatti la presente soluzione consente alle guarnizioni (6) di ogni pistone (2), di non scorrere a ridosso dei fori di alimentazione (4), in quanto questi vengono praticati all'esterno del pistone ed in modo non direttamente passante verso l'interno dello stesso.Al pistone (2), viene praticata una tornitura interna che determina la formazione di una scanalatura circonferenziale (5), formantesi dopo il montaggio del cilindro (1) nella rispettiva camera del pistone.The innovation in question was conceived in order to improve the oil pressure supply systems, which determines the displacement of the extensions forming a hydraulic telescopic cylinder. In fact, the present solution allows the seals (6) of each piston (2) , not to slide close to the supply holes (4), as these are made outside the piston and in a way that does not pass directly towards the inside of the same. At the piston (2), an internal turning is performed which determines the formation of a circumferential groove (5), which is formed after the assembly of the cylinder (1) in the respective piston chamber.
