Accumulators normally have a first chamber filled with a pressurized gas, a second chamber in communication with the pressurized fluid of a hydraulic system and an elastomeric member separating the chambers. In the subject invention, an accumulator is provided which has an elastomeric member disposed in a closed chamber of a housing. The elastomeric member has an outer surface with a non-uniform linear surface and a cavity extending inward from one end thereof and in communication with an inlet conduit. As the pressure is introduced into the cavity of the elastomeric member, the non-uniform linear outer surface is progressively forced against an interior surface of the closed chamber. The progressive compression of the elastomeric member acts to increase the volume of the cavity as the pressure of the fluid in the cavity progressively increases.

An accumulator adapted for use in a fluid system, comprising: a housing defining a closed chamber with substantially straight sides and having a longitudinally axis and an inlet conduit connected to the closed chamber; and an elongated elastomeric member being disposed within the closed chamber and having an outer surface extending along a length thereof and an internal cavity defined therein extending generally along the longitudinal axis of the closed chamber, the internal cavity being sealingly separated from the closed chamber by a portion of the elastomeric member and is defined by substantially straight sides, a closed bottom surface and an open end in communication with the inlet conduit, and at least a portion of the outer surface is an undulating surface that is spaced a predetermined distance from the substantially straight side of the closed chamber.
