LUBRICATING FAT FEEDING DEVICE FOR CONSTRUCTION MACHINERY, ESPECIALLY MARTINETES AND HYDRAULIC DRIVING DEMOLITION TENSES.

摘要

THE INVENTION REFERS TO A LUBRICATING FAT FEEDING DEVICE FOR CONSTRUCTION MACHINES PRESENTING A PUMP UNIT (1) CONNECTED TO A LUBRICATING FAT RESERVE (22) CONTAINER, WITH A PAD (3) THAT MOVES IN VAIVEN RECTILINE FORM WITHIN A HOLLOW SPACE (4). TO ENSURE THAT A COMPRESSIBLE ENVIRONMENT (AIR) ASPIRED BY EXAMPLE TO THE HOLLOW SPACE (4) IS EVACUATED AS FAST AS POSSIBLE, THE HOLLOW SPACE (4) IS SUBDIVIDED BY A COMPLEMENTARY DEVICE IN A COMPRESSION SECTION AND A CONTINUED SECTION PUMPING (F). THROUGH THE COMPLEMENTARY DEVICE, OPERATED BY A SUFFICIENTLY HIGH PRESSURE LEVEL OF THE COMPRESSION SECTION (V) THAT IS ONLY REACHED WHEN LUBRICATING GREASE PUMP IS ESTABLISHED, A RETURN COMMUNICATION IS THROUGH BLOCKED, BETWEEN THE COMPRESSION ) AND THE FEEDING CONDUCT (14) AND BETWEEN THE FAT RESERVE CONTAINER (22) AND THE HOLLOW SPACE (4), WHILE THE HEAD OF THE PACKAGE (3) IS FOUND DURING HIS ADVANCE (ARROW 7) INSIDE THE SECTION OF COMPRESSION (V).
