Abstract

Martello idropneumatico azionato dall'azione reciproca di un pistone di percussione e di una valvola di controllo direzionale, comprendente un pistone avente gradini di diametri grandi e piccoli che separano l'interno di un camera di pistone prevista per far entrare detto pistone in quattro camere, una prima camera comunicando per mezzo di un primo passaggio con una linea e pressione, la seconda camera essendo definita da un gradino della parte mediana di detto pistone che la connette ad un linea di scarico, la terza essendo definita da un gradino formato su di una porzione superiore di detto pistone e la quarta definendo una camera per gas separata dalla terza camera tramite un fermo di tenuta, una camera di valvola prevista per introdurre un sistema a valvola che è disposto parallelamente a detta camera si pistone, un passaggio per convertire una linea a pressione di fluido o olio in una linea di scarico e che connette detta camera di valvola con la seconda camera, un passaggio per far ritornare un fluido o olio scarico che è convertito in stato depressurizzato dopo aver lavorato, un primo passaggio è previsto per erogare un fluido sotto pressione da detta luce di ingresso nella prima camera, un secondo passaggio è previsto per erogare un fluido sotto pressione da detta luce di ingresso in detta camera di valvola camera autopressurizzabile, ed un passaggio previsto per mettere in comunicazione detta camera di valvola con la terza camera.
