Definitions

  • the present invention relates to hydraulic accumulators with bladder that is to say of the type having an enclosure within which is a bladder deformable, usually rubber, inflated with a gas which is usually nitrogen.
  • the object of the present invention is to overcome all its disadvantages butt two or more bladders.
  • FIG. 1 represents an accumulator of known type constituted by: an enclosure 1, generally of steel so as to withstand high pressures; a bladder deformable 2 disposed within said enclosure.
  • This bladder 2 separates the volume inside the enclosure 1 in two parts: a part 3, connected by an orifice 4 to a circuit hydraulic; a portion 5 filled with gas under pressure, usually nitrogen.
  • the bladder 2 has, at its lower part, an orifice 6 by means of which it is fixed in a sealed manner at the bottom of the enclosure 1 via a plug 7 allowing to inflate the bladder.
  • the bladder 2 At its upper part the bladder 2 is provided at its summit end with a stop 8, which is intended to prevent the top end of bladder 2 from entering the orifice 4 when the hydraulic liquid is expelled from the volume 3 under the effect of the gas under pressure in volume 5 and dilating bladder 2.
  • the bladder 2 when the volume inside the accumulator is important, greater than 10 liters, the bladder 2 is consisting of a plurality of elements connected to each other.
  • the bladder 20 may be advantageously identical to the bladder 2 which allows to standardize the constituent parts of the accumulators.
  • FIG. 3 represents a second embodiment in which the same elements bear the same references.
  • the bladder consists of three bladders 22, 23 and 24 which are assembled to each other by two connecting pieces 9, through an orifice 10 so that their internal volumes 52, 53 and 54 communicate with each other.
  • the upper bladder 22 may, as shown, be identical to the bladder 20 of FIG. 2 and thus comprises a stop 8 intended to come against the orifice 4.
  • the lower bladder 24 may also be identical to the element 21 of FIG. have at its base an orifice 64a, identical to the orifice 61a of the bladder 21 of the figure 2, in order to be attached to the inflation plug 7.
  • the bladders 20, 21, 22, 24 are identical. It suffices for that orifices 60, 61, 61a, 62, 64 and 64a, as well as that to receive the abutment 8 are identical, parts 7, 8 and 9 having the same diameter.
  • intermediate bladder 23 a bladder identical to the bladders 20, 21, 22 and 24.
  • the advantage in this case is that one has a modular bladder with which one can make bladders to one, two, three, four or even more elements; what significantly reduces the cost of producing batteries.
  • Figures 4 and 5 show an alternative embodiment of the accumulators shown in Figures 2 and 3.
  • This stack of bladders may have the disadvantage of not always remaining rigorously centered along the longitudinal axis of the body 1 of the accumulator which, among other things, may hinder the use of such a battery in horizontal position.
  • the plug 7 is extended, inside the lower bladder 51 or 54, by a sleeve hollow 70 in the inner bore 71 which is threaded freely a rod 11 which passes through the assembly part (s) 9 by their orifice (s) 10 and which is screwed to its end 12 in the stop 8.
