HYDROPNEUMATIC ACCUMULATOR WITH SOFT CELLULAR FILLER Russian patent published in 2010 - IPC F15B1/08 

FIELD: machine building.

SUBSTANCE: accumulator is provided for recovery of hydraulic energy in hydrosystems with high level of pulsing. Accumulator includes casing in which gaseous and liquid ports are connected correspondingly to gaseous and liquid vessels of variable volume, separated from each other by mobile separator. Soft cellular filler fills gaseous vessel so that displacement of separator, reducing capacity of gaseous vessel compresses mentioned filler. Filer is connected to inner walls of gaseous vessel with ability of expansion of filler by means of separator, increasing capacity of gaseous vessel. Accumulator contains security facilities of interface of filler against disruption, implemented with ability of reduction of local deformation of interface of filler at jerking of separator.

EFFECT: there is prevented collection of permanent deformations of filler at multiple cycles of recover and destruction at irregular motion of separator with sharp jerking.
