摘要： Accumulators normally are teed into existing conduits and require large amounts of space or are placed in spool type bores having a spring biased piston slidably disposed therein. Most times these accumulators require a bladder that is vented to the atmosphere or a fluid chamber connected to a reservoir. In the subject invention, an accumulator 24 is provided that has a fluid filled member 36 which can be disposed in a closed chamber 32 of a housing 30 and connected to a source of pressurized fluid. The fluid filled member 36 has a fixed maximum surface to volume ratio and is capable of being compressed when subjected to a pressure higher than the pressure within. The accumulator may be integral with other components in the hydraulic system 10 and can be made with varying volumetric capacities and varying precharged pressures in order to match the requirements of the hydraulic system.

摘要： An improved hydraulic accumulator is introduced wherein a valve mechanism is used to seal a hydraulic fluid before the pressure charged piston reaches the end of the accumulator to minimize the loss of compressed gas by eliminating the pressure differential when the piston is fully extended, thereby prolonging the fatigue life of the accumulator vessel. Reduction of the pressure loading on the vessel will also prolong the life of the piston seals and metal bellows effectively extending the accumulator life and effectively allowing design for weight reduction and preservation of the integrity of the complete hydraulic or pneumatic system.
摘要翻译：引入了一种改进的液压蓄能器，其中阀机构用于在压力充满的活塞到达蓄能器的端部之前密封液压流体，以通过消除活塞完全伸长时的压力差来最小化压缩气体的损失，从而延长蓄能器容器的疲劳寿命。降低容器上的压力负载也将延长活塞密封件和金属波纹管的使用寿命，有效延长了蓄能器的使用寿命，并有效地允许设计减轻重量并保持整个液压或气动系统的完整性。

摘要： A toilet flushing system includes a fresh water feed, a fluid storage container connected to the fresh water feed, and a supply line coupled to the storage container and a toilet. The fluid storage container has a container casing and first and second separating diaphragms within the casing. The separating diaphragms define first, second and third partial chambers within the container casing for separately receiving gas and fresh water. The second partial chamber is defined between the separating diaphragms and receives gas. A valve in the fresh water feed and the supply line, closes the fresh water feed and the supply line. The valve is movable between a first switch position for filling the partial chamber with fresh water to be delivered to the toilet and a second switch position in which the third partial chamber simultaneously is filled with a medium.

摘要： An elongate tank for transport or for storage in bulk of semisolid and fluid materials, such as grease and oil. The tank has an outlet at one end thereof for discharging material contained therein, and has a generally cylindric interior surface. A generally cylindric piston is sized to slide in the tank and is movable in a direction toward the outlet thereby to place material in the tank through the outlet. The piston comprises a piston member and an elastic annular seal carried in a circumferential channel around the piston member. The seal has an annular base and an annular crown disposed radially outwardly of and joined to the base with a fluid chamber between the base and crown. The seal is expandable by introducing fluid into the fluid chamber. Expansion of the seal causes the crown to be pressed radially outwardly against the interior surface of the tank so that when the piston member slides in the tank a portion of the crown is maintained in sliding engagement with the interior surface thereby to wipe the material therefrom and to seal the piston member relative to the tank. The crown has side surfaces and an outwardly facing surface. The outwardly facing surface of the crown has two sloping surface portions and a circumferential ridge intermediate the side surfaces. The ridge is defined by the junction of the surface portions.

摘要： A fluid storage and expulsion system comprising a tank 12 with an internal flexible diaphragm assembly of dual diaphragms 17,18 in back-to-back relationship, at least one of which is provided with a patterned surface having fine edges such that the diaphragms are in contact along said edges without mating contact of surface areas to thereby form fluid channels 27 which extend outwardly to the peripheral edges of the diaphragms. The interior wall of the tank at the juncture of tank sections 14,15 is formed with a circumferential annular recess comprising an outer annular recess portion which forms a fluid collection chamber 40 and an inner annular recess portion which accommodates the peripheral edge portions of the diaphragms and a sealing ring 38 in clamped sealing relation therebetween. The sealing ring is perforated with radially extending passages 39 which allow any fluid leaking or diffusing past a diaphragm to flow through the fluid channels 27 between the diaphragms to the fluid collection chamber. Ports 21,23, connectable to pressure fittings are provided in the tank sections for admission of fluids to opposite sides of the diaphragm assembly. A drain passage 42 through the tank wall to the fluid collection chamber permits detection, analysis and removal of fluids in the collection chamber.

摘要： In the interior of the housing of an accumulator, a metallic bellows and a self-seal mechanism are arranged. The metallic bellows partitions the interior of the housing into a gas chamber and a liquid chamber. The self-seal mechanism includes an elastic seal member and a face which the elastic seal member opposes. When the bellows is compressed to the predetermined extent due to introduction of a compressed gas into the gas chamber, the elastic seal member is brought into contact with the face, thus closing a flow port. The elastic seal member has a slanted face, so that a wedge-shaped liquid guide gap is produced when the elastic seal member is in contact with the face. When, in this condition, the compressed liquid is introduced into the flow port, part of the liquid enters the liquid guide gap, thus permitting the seal member to easily separate from the face.

摘要： Method of manufacturing an accumulator device including a shell portion having an open mouth and a cap member affixed over the open mouth after a bladder assembly has been secured within the shell portion of the pressure vessel. The method comprises in the provision of an exterior annular weld connecting the cap member to the outer wall portion of the vessel as well as an interior weld connection between the interior wall portion of the cap member and the upwardly directed end edge of the mouth of the pressure vessel. By locating the metallic skirt member which functions to support the bladder such that the top of the skirt forms a dam for containing the weld which secures the cap member interior to the uppermost edge of the pressure vessel, the possibility of weld fragments falling into the bladder causing damage to the latter is minimized.
