Definitions

  • the invention relates to a modular pressure vessel comprising a center section having a rounded, longitudinal sidewall, the sidewall defining a longitudinal axis and extending from a first opening at a first end of the center section to a second opening at a second end of the center section that is opposite the first end,
  • Pressure vessels contain pressurized fluid, such as air.
  • pressurized it is meant the pressure inside the vessel is greater than the ambient atmospheric pressure.
  • Pressure vessels have many applications, such as in automotive air suspension systems, for portable air supply systems, industrial air tanks, and others. Typical pressure vessels are limited in their capability, where a given vessel structure is suited for only one specific application and cannot be easily changed or expanded for other applications.
  • Existing pressure vessels require complex manufacturing methods and produce unreliable and non-durable fluid retaining structures. Repairs thereto often are required, which are expensive and labor-intensive.
  • the US patent US 10,436,386 B2 describes a modular pressure vessel consisting of an extruded center section with two end caps, which creates a space for storing a pressurized fluid and containing a rail system for mounting technical components, like a compressor for instance, within the vessel.
  • the problem underlying the present invention was to provide a modular pressure vessel which does not suffer from the disadvantages of those suggested by the art.
  • the invention relates to a modular pressure vessel comprising a center section having a rounded, longitudinal sidewall, the sidewall defining a longitudinal axis and extending from a first opening at a first end of the center section to a second opening at a second end of the center section that is opposite the first end,
  • the present disclosure generally relates to a modular pressure vessel having two separate compartments.
  • the modular pressure vessel comprises the following features:
  • Fig. 1 shows a modular pressure vessel (1), compromising a center section (2), two end caps (3, 4) and a divider cap (7) in the center, which is visible in Fig. 3 .
  • the divider cap (7) splits the vessel into two compartments (5 ,6), of which the first one (6) is housing a compressor (8) and related components, as well as a pressure reduction valve (10).
  • the second compartment (5) is used to store pressurized air.
  • the center section (2) of the vessel consists of an extruded aluminum profile, which has four holes along its longitudinal axis to guide threaded rods (11) through it. These threaded rods (11) are used to attach the end cap of the pressurized compartment (4) to the divider cap (7). In addition to that, the threaded rods (11) are used as guides for mounting the compressor (8) within the first compartment (6).
  • the extruded center section (2) is mechanical processed to remove the longitudinal holes in the length of the first compartment (6), to ensure enough space for the compressor and for ease of mounting the divider cap (7). All caps are centered and guided within the center section using an O-Ring. The pressure compartment is sealed using a profiled seal between the caps and the machined surfaces of the center section.
  • Fig. 8 shows the layout of the compartment (6) housing, the compressor (8) and related components.
  • the compressor (8) is mounted to two metal sheets (12), which are decoupled from the center section and the caps. This decoupling (13) is reducing the overall noise level when the compressor is running.
  • the outlet port of the compressor (8) is connected to the second compartment (5), so the sucked in air is compressed into the pressurized compartment (5).
  • Fig. 9 shows that pressure sensor (14) is mounted to the dividing cap (7) to measure the pressure inside the pressurized compartment (5).
  • the compressor (8) is either switched on or off by the internal control unit.
  • a fan can be mounted to the ventilation slots which are machined into the center section (2) to force air exchange between the ambient and the first compartment.
  • the airflow is of additional use to cool the compressor (8).
  • Ventilation openings can also be added to the cap of the first compartment (3), which also includes the electrical connections as well as the compressed media output.
  • Running the compressor (8) at ambient pressure and with constant exchange of air between the ambient and the compartment (6) assures, that there will not be excess humidity accumulating within the compressor (8). In addition to that, it is not necessary to decompress the compressors (8) head in order to run it, which leads in less mechanical stress for the parts. All in all, the lifetime of the compressor (8) can be vastly increased, and the compressor (8) can be run to its specifications.
  • Splitting the pressure vessel (1) into a pressurized (5) and a not pressurized compartment (6) results into a loss of volume to store compressed air in.
  • the internal pressure of the vessel (1) may be increased up to 18 bar, which results in a near equalization of the product of pressure and volume. This means, that nearly the same amount of media can be stored within the vessel (1).
  • the product of pressure and volume increases at a rate of around 30% greater than current implementations of the state of the art.
  • a pressure reduction valve (10) is added to the device within the first compartment (6). This valve assures (10), that the output pressure does not exceed 12 bar.
  • the second compartment (5) and the compressed media output are connected via a hole in the dividing cap (5), as well as a pipe.
