Definitions

  • the invention relates to a pressure accumulator with a housing, which consists of an upper and a lower part and the interior is divided by an elastic partition into a gas and a liquid space, the upper part until it rests against a stop in the cylindrical opening of the lower part is inserted and the edge of the cylindrical opening of the lower part is deformed without cutting around the edge of the upper part.
  • a pressure accumulator which has a lower part, in the cylindrical opening of which an upper part is inserted.
  • the depth of insertion of the upper part into the lower part is limited by the abutment of the edge of the upper part on a shoulder on the inner wall of the lower part.
  • this housing is subdivided by an elastic partition into a gas and a liquid space, the partition being inserted with a bead formed around its periphery into a groove which is open radially outwards at the region of the upper part which is pushed into the lower part.
  • the upper part in the area of its opening has a radially outwardly protruding circumferential projection of approximately rectangular cross-section, and in the inner wall of the lower part in the area of the opening a radially inwardly open annular groove is formed, before the assembly of the Housing, the inside diameter of the lower part on the side facing away from the opening is smaller and on the side facing the opening larger than the outside diameter of the extension of the upper part, so that the upper part into the lower part until one side surface of the extension lies against the side wall remote from the lower part opening the annular groove is insertable and the cross-section of the annular groove is designed prior to the assembly of the housing such that it acts on the outer circumference of the lower part in the region of the annular groove with a radially inward component and a compo directed axially towards the lower part opening Nente the cross section of the approach can be adjusted and in the assembled state, the approach of which engages in the lower part of the inserted upper part in the annular groove.
  • the side surface of the extension which is farther from the opening of the upper part is inclined radially inward in the manner of an undercut.
  • this causes the neck of the upper part to be braced axially in the annular groove of the lower part and thus a fixed installation position.
  • This increases the axial bracing that already occurs due to the axially elastic springback of the axially deformed part.
  • Aluminum is particularly suitable as a material because of its favorable elastic properties.
  • the inside diameter of the lower part is advantageously approximately the same on both sides of the annular groove.
  • the upper part is advantageously formed at the mouth of its opening with a circumferential cylindrical edge which can be inserted into a correspondingly designed cylindrical guide in the lower part on the side of the annular groove facing away from the opening is.
  • a simple way of fastening the elastic partition in the housing is achieved in that in the lower part on the side facing away from the mouth opening An annular groove is formed in the annular groove, which is open in the axial direction towards the mouth opening and into which a bead is formed which is circumferentially formed on the edge of the partition wall and on which the end wall of the mouth opening of the upper part is in contact when the housing is assembled.
  • the pressure accumulator shown in the drawing has a housing which consists of a lower part 1 and an upper part 2.
  • a radially inwardly open annular groove 3 is formed in the inner wall, the cross section of which is approximately rectangular in the assembled state of the housing.
  • the inner wall is designed as a cylindrical guide 4, into which the upper part 2 can be inserted with a cylindrical rim 5 which is formed at the mouth of its opening.
  • the end of the cylindrical guide 4 on the side facing away from the annular groove 3 simultaneously forms the radially outer one Side wall of a circumferential groove 6 which is open in the lower part 1 in the axial direction towards the mouth opening.
  • An elastic partition 7 dividing the housing interior into a gas space 9 and a liquid space 10 is provided at its edge with a circumferential bead 8 which is inserted into the circumferential groove 6 of the lower part 1.
  • the end wall 11 of the mouth opening of the upper part abuts on the bead 8 and thus holds it in its installed position in the groove 6.
  • the upper part 2 is formed in the region of its cylindrical mouth opening with a radially outwardly projecting peripheral projection 12, the cross section of which corresponds to the cross section of the annular groove 3 when the housing is assembled.
  • the side surface 13 of the extension 12 which is farther from the opening of the upper part 2 is inclined radially inward in the manner of an undercut.
  • the upper and lower parts Before the housing is assembled, the upper and lower parts have the shape shown in FIG.
  • the inner diameter of the lower part 1 is smaller on the side of the annular groove 3 facing away from the opening and larger on the side of the annular groove 3 facing the opening than the outer diameter of the extension 12. This enables the lower part 2 until one side surface 14 of the extension lies against the opening 12 on the side wall 15 of the annular groove 3 which is more distant from the lower part opening.
  • the cross section of the annular groove 3 is formed before assembly of the housing so that it is through a the pressure acting on the outer circumference of the lower part 1 in the region of the annular groove 3 is deformed such that after the deformation it corresponds to the cross section of the extension 12.
  • the pressure acting on the lower part 1 has a radially inwardly directed component and an axially directed component towards the lower part opening. Such pressurization can be achieved, for example, during a pulling process.
  • the annular groove 3 engages around the neck 12. Relieving the lower part 1 of the deformation pressure leads to a springback of the deformed part of the lower part 1 in the axial and radial directions. Since the side surface 13 of the shoulder 12 is inclined radially inwards and the side wall 16 of the annular groove 3 is deformed to a corresponding inclination, the radial springback also causes the shoulder 12 of the upper part 2 to be braced in the annular groove 3 in addition to the axial springback. so that a secure and firm connection of the two housing parts 1 and 2 is achieved under all operating conditions.
