Abstract
Accumulators/compensators for pressurized fluent material systems are provided, in which a continuous substantially non-permeable, flexible membrane (like a bellows) surrounds or is surrounded by a non-gaseous support medium, all within a surrounding housing. Various combinations of support media, which may include internal gas-filled cavities, are described and illustrated.
Claims32
An accumulator/compensator apparatus for accommodating pressure fluctuations in a pressurized fluent material system, comprising:
- a housing, operably configured to be connected, in communication with a pressurized fluent material system;
- a substantially non-permeable, flexible membrane, fabricated as an inelastic, substantially flexible tubular member, operably disposed within the housing, to have a surface in contact with the system fluent material of the pressurized fluent material system, so that upon occurrence of a pressure differential across the substantially non-permeable, flexible membrane, caused by a change in the pressure of the system fluent material, the substantially non-permeable, flexible membrane will be prompted to undergo a change in dimension in response to the pressure change in the system fluent material contacting the surface of the substantially non-permeable, flexible membrane;
- at least one non-gaseous support medium, operably disposed in operable contact with the substantially non-permeable, flexible membrane, for providing yielding resistance to dimensional change by the substantially non-permeable, flexible membrane in response to said pressure fluctuations of the system fluent material.
