Definitions

  • accumulators are manufactured by cold deforming a sheet metal disc in two operations, namely a first operation making it possible to obtain a cylindrical or conical blank whose end has a domed bottom and is provided with a gas filling orifice. first chamber, and a second operation in which, after fixing the membrane in the envelope using the cup, the cylindrical part of the blank is constricted to give it a spherical shape having an axial orifice in which it is crimped and welds a liquid supply fitting into the second chamber.
  • the cup may have a conical edge which cooperates with a conical edge of the membrane during assembly of the latter.
