OPERATING PRINCIPLE

Due to the compressibility of the gas, nitrogen, the diaphragm accumulator enables to store, stock and return a liquid

under pressure.

V0 = Capacity in nitrogen of the accumulator

V1 = Gas volume at the minimum hydraulic pressure

V2 = Gas volume at the maximum hydraulic pressure

V = Returned and/or stored volume between P1 and P2

P0 = Initial preload of the accumulator

P1 = Gas pressure at the minimum hydraulic pressure

P2 = Gas pressure at the maximum hydraulic pressure

  A - The diaphragm is in the
P0 precharge position, which means
that it is only filled with nitrogen.
V0
 
A The knob closes the hydraulic orifice
and prevents the destruction of
 
  the diaphragm.
  B - Position at the minimum
P1 operating pressure : there must be
a certain amount of fluid between
V1
B the diaphragm and the hydraulic
orifice, such that the knob does not
 
  close the hydraulic orifice.
  Thus, P0 must always be < P1.
  C - Position at the maximum
P2 operating pressure: the volume
change Delta V between the
V2
  minimum and maximum positions
C V
  of the operating pressures represents
  the fluid quantity stored.

THE BENEFITS FOR YOU

The adaptation of a hydraulic shock absorber made up of a diaphragm accumulator improves driver comfort and offers immediate response times when driving over obstacles and the same flexibility for variable operating conditions.

0 < speed < 50 kph

3.5 < load variation < 100% Identical flexibility depending on your use.

The same EC regulation compliant accumulator can be used in over 35 destination countries, thus facilita- ting their free movement.
