Title: Hydropneumatic accumulator
Inventor: PRUESS LUDWIG DIPL ING
IPC: F15B1/14
Filed: 1989-01-28
Abstract: A hydropneumatic accumulator with a housing (1), composed of at least two housing parts (2) and (3), and a flexing diaphragm (9) which subdivides the interior of the housing (1) into a gas space and a fluid space and is firmly held against the inner wall of the housing (1) by means of a retaining member. When fluid pressure exceeding the gas pressure is admitted, the maximum stroke of the diaphragm (9) is limited by a cap-like body (6) which is made of a dimensionally stable and gas-tight material. When fluid pressure falling below the initial gas pressure is admitted, the diaphragm (9) bears against the inner wall of the housing part (3). In this hydropneumatic accumulator, the diffusion of gas into the hydraulic working medium is restricted to the greatest possible extent by virtue of the fact that the cap-like body (6) has a small opening cross-section (5) in relation to the housing diameter and, when the diaphragm (9) is not at the maximum stroke, subdivides the gas space into two spaces communicating with one another, and pressure is applied to the diaphragm (9) in such a way that it bears almost constantly against the cap-like body (6) during the operating period of the accumulator.   <IMAGE>
