Abstract:
1. An autonomous valve assembly for the regulation and elevation of the pressure in pneumatic equipment, being an assembly of the type that comprises an air-regulating body with an compressed air inlet, connected to a source of compressed air, a valve body connected to said regulating body to receive compressed air from said air-regulating body and which includes an air-diverter plunger with reciprocating movement to cyclically divert the compressed air through connection ducts to a pressurization plunger assembly with reciprocating movement within a pressurization casing defining external pressurization chambers and internal pressurization chambers, inside of said pressurization casing the compressed air provided in said air inlet is compressed and the pressure is elevated above the pressure at a point of entry, said pressurization plunger assembly including a rod that is slidingly mounted within a duct of said valve body, wherein said duct crosses the valve body, connecting said internal pressurization chambers, presenting said rod, at its ends, two pressurization plungers that sealingly slide within said air pressurization casing, said rod being slidingly mounted using said valve body, said valve body having inlet valves, to channel the highly-compressed air for its posterior usage and outlet valves for the outlet of the air whose pressure has been increased, and valve plungers, to cyclically direct the air towards said diverter plunger to make said diverter plunger move cyclically with reciprocating movement, an elevator being characterized by: said air regulation body consisting of a first air pressure regulator adjusted to a first pressure and a second air pressure regulator adjusted to a second pressure, being mounted between said pressure regulators a selection switch to activate one of the two pressure regulators.
