Abstract
This invention relates to a fluid accumulator comprising a wall (2) encompassing a reservoir (1) for receiving the fluid, part of the wall being elastically deformable. The wall (2) of the fluid accumulator comprises a first wall portion (2A) that is made of a first elastically deformable composite, with fibrous reinforcement material applied in a first density, and a second wall portion (2B) that is made of a second composite with fibrous reinforcement material applied in a second density and an elastic deformability that is the same as or different from the elastic deformability of the first wall portion, the density of the fibrous reinfrocement material in the first and second wall portion (2A, 2B) being different.
Claims14
A fluid accumulator comprising a closable reservoir for receiving the fluid under a working pressure, which is enclosed by a circumferential side wall and a first and second end wall on opposite end parts of the circumferential side wall, wherein the circumferential side wall comprises in the longitudinal direction, a first circumferential wall portion made of a first elastically deformable composite material, which is deformable under the action of the mean working pressure and a second circumferential wall portion made of a second composite material, which is essentially undeformable under the action of the working pressure.
