Definitions

  • FIG. 1 is a longitudinal sectional view of the pressure vessel according to the invention
  • FIG. 2 is a detail view of the periphery of the deformable partition
  • FIG. 3 is a detail view of the periphery of the partition mounted on the closure member before it is positioned in the container of the pressure vessel.
  • the pressure vessel comprises a container 11 of strong, rigid material such as steel or aluminum capable of withstanding the pressure to which the unit is subjected.
  • the container is cylindrical along the major portion of the body thereof and has a hemispherical end 12 which has an opening 13 in which an outlet member 14 is mounted having a port 15 through which fluid such as oil under pressure may flow.
  • the cylindrical portion of the container 11 at the mouth thereof is of larger diameter than the main body of the container, defining a curved shoulder 16.
  • FIG. 1 has an axial opening .18 designed to receive a suitable air connection (not shown).
  • the side wall '19 of the cover member 16 defines a substantially cylindrical portion adapted to fit into the cylindrical mouth of the container lll.
  • the outer periphery of the cover member is curved in vertical cross section as at 20 so that it may seat on the correspondingly curved shoulder 16 of the container.
  • the portion 19a of said cylindrical portion 19 is of outer diameter substantially the same as the inner diameter of 'the container adjacent the curved shoulder 16 thereof so that it will fit snugly therein to center the cover member in the container.
  • the lower portion 191) of cylindrical portion '19 is of outer diameter less than the inner diameter of the container to define a space therebetween to receive the periphery of a detormable partition 22.
  • the partition 22 illustratively is a collapsible and expansible bladder having an enlarged mouth and which desirably is of resilient mate-rial such as rubber or synthetic plastic of like physical characteristic.
  • the bladder defines two chambers in the pressure vessel, i.e., an oil chamber 23 which is in communication with the passage.
  • the outer surface of the bladder 22 has 'an annular outwardly extending flange 31 of length substantially equal to one-half the length of the bead 27 with the lower surface of the flange 31 defining substantially a right angle as at '32 with respect to the adjacent wall surface 33 of the bladder.
  • the lower cylindrical portion 19b of the cover member has two spaced annular grooves 3 4, 35 in its outer surface in which the annular beads 27, 28 respectively are positioned.
  • the upper wall 36 of groove 34 is preferably inclined upwardly from the side wall 37 of the groove 34 and the length of the wall portion 38 intervening between grooves 34, :35 is less than that of the portion 29 of the bladder intervening between beads 27 and 28.
  • the beads 27 and 28 are of transverse thickness such that when the bladder 12 is mounted on the cover member I17 with the beads 27, 28 positioned in grooves 34, 35, respectively, prior to insertion of the cover member and bladder 22 into the container, as shown in FIG. 3, the
  • outer wall surface 33 of the bladder will extend transversely beyond the cylindrical portion
  • the annular flange '31 will also extend outwardly beyond the wall surface 33.
  • the lower bead 28 With the cover member 17 so mounted, the lower bead 28 will be compressed into groove 35 with the rounded end 42 of the depending portion 19 embedded into the inner wall of the bladder inwardly below the lower bead 28.
  • the top surface 42' of end 42 defines an abutment for the undersurface 28' of bead 28, so that the latter will be hooked onto said rounded end 42.
  • the upper bead 27 will be compressed in groove34 and will be deformed so that it will engage the inclined surface 36 of groove 34 substantially filling the latter.
  • beads 27 and 28 will also cause them to deform toward each other vertically so that the material 29 between the beads 27, 28 will be con voluted as shown at 45 in FIG. 1 and by reason of the spacing between the opposed wall of the container and the periphery of portion 38 of the cover member 17, the convoluted portion will be loosely supported in such space.
  • the bladder 22 is charged with gas under pressure and then the oil chamber 23 is charged with oil under pressure greater than that of the gas in chamber 25.
  • the bladder 22 will contact and expand exerting tension on the wall thereof. This tension will be exerted first on the lower bead 28 and possibly move it out of its groove slightly so as to break the fluid seal caused by the compression of the bead 28.
  • a pressure vessel has been provided which by reason of the provision of two beads with a convoluted portion therebetween, one of which beads form the fluid seal in conjunction with an annular groove in the support member for the bladder and the other of which acts as a hooking member in conjunction with another annular groove in the support member, the convoluted portion will prevent transmission of even the slight displacement imparted to the hooked bead during use of the pressure vessel, to the sealing bead, so that dependable sealing action will be afforded.
  • a pressure vessel comprising a rigid hollow container having a mouth at one end and having a port at the other end, a cover member adapted to be positioned in the mouth of the container, said cover member having a port, means securely to retain said cover member in place, a flexible partition of resilient deformable material positioned in said container and intervening between said ports, said partition having two annular beads spaced apart a substantial distance and located near its periphery and positioned on the side of the partition adjacent the port in the cover member, said cover member having a head and a cylindrical portion extending inwardly from said head into the container and transversely spaced therefrom, said cylindrical portion having a pair of spaced annular grooves in its outer surfaceadapted to receive the annular beads on said partition, the groove remote from the mouth of the container defining an abutment for the associated bead, the spacing between the bottom of said grooves and the adjacent surface of the container, and the unstressed transverse thickness of said beads being such as to place both of said beads under lateral compression when assembled in said container
