Definitions

  • the invention relates to a 3-chamber cylinder for liquid or gas Working medium.
  • a hydraulic cylinder is known from the prior art, which works on the principle a flow chamber and a return chamber works. All telescopic presses too work according to the same system.
  • the invention relates to a 3-chamber cylinder for liquid or gas as Working medium, consisting of a sealing axially displaceable in an inner cylinder guided hollow piston with a hollow piston rod, the Inner cylinder is provided at one inner end with a cylinder bottom which the hollow piston rod is sealingly guided, and one over an outer Cylinder base firmly connected to the hollow piston rod, sealing on the Inner cylinder axially displaceably guided outer cylinder, so that a first flow chamber between an outer cylinder bottom of the inner cylinder and the hollow piston is formed, a second flow chamber between the outer Cylinder base of the outer cylinder and the inner cylinder base of the inner cylinder is formed around the hollow piston rod and a return chamber between the inner cylinder bottom of the inner cylinder and the hollow piston is formed around the hollow piston rod.
  • the 3-chamber cylinder according to the invention can be used in machines and systems Hydraulic cylinders can be used individually or in combination.
  • the invention Cylinder can be used in all machines and devices in which conventional Cylinders with a 2-chamber cylinder system (forward and return) are used in Energy generation systems, compressors, as compressors and as pressure transducers.
  • the design can also be used in internal combustion engines by the return chamber c works as a combustion chamber and the explosion shocks act on both pistons or the first flow chamber a and the return chamber c act as combustion chambers and the explosion impacts on four piston surfaces act or all three chambers as combustion chambers in cycle a + b to c, where b is the second flow chamber.
  • the 3-chamber cylinder works on the same principle in all areas, namely with 2 flow chambers (a and b) and a return chamber (c) or vice versa.
  • a 3-chamber cylinder according to the invention has compared to the conventional Cylinder different advantages on:
  • the pressure in Chamber c increased to 100% and by operating the chamber c the pressure in the Chambers a and b can be reduced to 100%.
  • the gravity pressure can be used of the 3-chamber cylinder by acting on the enlarged piston area by up to be increased to 95%.
  • Figure 1 shows a longitudinal section through the 3-chamber cylinder through the Openings 51 to chamber a and 58 to chamber b driven with liquid or gas will (advance). The liquid escapes through the openings 59 and 55 or the gas from chamber c (return).
  • the liquid must or the gas can be pumped into chamber c at twice the pressure since this working stroke only takes place from a chamber c and not, as with compressed air, from two chambers.
  • Figure 2 shows the longitudinal section of the 3-chamber cylinder in the retracted and Figure 3 in the extended state.
