Abstract: The invention relates to a hydropneumatic pressure reservoir (1) with a housing formed from at least two housing shells (3, 5) which may be connected together. At least the end region of the one housing shell (5) comprises an outwardly-extending, funnel-like guide surface between the free end thereof and a sealing element for bringing together the both housing shells (3, 5). At least one elastic sealing element (41) is provided on at least one retaining surface for generation of a tensioning force on the boundary region (21) of the membrane (13). A simplified construction with improved sealing in the critical connection region of the pressure reservoir may thus be achieved.

Abstract: The invention relates to machine building and may be used for the starting fuel expulsion at the liquid-propellant rocket engine start. A tank comprises a structural envelope made in a form of hemisphere with a tube connection having a ring groove in its surface. A tightening ring of the structural envelope. An elastic diaphragm made in a form of hemisphere integrated with a cylinder provided with an end projection that fits into the ring groove. A bottom is made in a form of a sphere part. A thin-walled ring with a shoulder is introduced that is mounted between the tightening ring and elastic diaphragm in the place of its end projection location. The tube flange is provided with an end projection. The tightening ring is equipped with a lateral flange providing a possibility for the thin-walled ring shoulder tightening by it to the ring projection of the tube flange. The external surface of the tightening ring and internal surface of the tube flange are made tapered in the direction from the ring groove to the hemisphere of the structural envelope above the ring groove. The bottom is made to be hollow and its internal surface is provided with holes. A splitter is introduced that is mounted in the bottom space.

Abstract: Methods and apparatus for (a) increasing expansion tank "acceptance" (defined herein as working fluid storage capacity); and (b) adjusting the rate of pressure variations within a prespecified range in precharged fluid storage systems (for example, holding pressure down below a prespecified threshold value for a given volume of acceptance, stored water temperature level, etc.). A "volatile" fluid (defined herein as a fluid having a boiling point within the predetermined pressure and temperature operating ranges for a given system), is used at least in part as the expansion fluid in an expansion tank included in a fluid storage system. The volatile fluid, whether pure or combined with an ideal gas to temper the expansion fluids sensitivity to temperature, can be used to realize a relatively constant pressure "vapor spring" to make internal expansion tank pressure relatively independent of acceptance (where the term "relatively" in each instance is referring to a comparison between the use of an expansion fluid that contains a volatile liquid and one that does not contain such fluid).

Abstract: An expansion tank with an improved diaphragm seal includes a seal for the joint between the flexible diaphragm and either an optional. non-flexible diaphragm or the tank wall, the providing of a seal support that prevents collapse, delamination, or tearing of the 5 tank shell wall. The tank shell may be formed of two substantially hemispherical domes joined together, either directly or at the two ends of a substantially cylindrical section. One of the segments forming the shell of the expansion tank, further comprises an extension lip, extending inwardly of the tank and around the entire circumference of the inner surface of the shell wall, located substantially near the junction of two of the sections 10 forming the tank. This extension lip may be made from the same material as the tank wall, or may be part of a separate circumferential connector interconnecting two of the sections of the tank wall.
