    Abstract: A helium charged accumulator is disclosed for use in hydraulic fluid pressure systems. The size of the accumulator is optimized for particular operating conditions of specific applications of the hydraulic systems by means of a formula. The formula has, as its terms, the volume of the hydraulic fluid required to power a given device, the compressibility factor of the particular gas used and the temperature and pressure of the gas at the beginning of, during, and at the end of the operation cycle of the accumulator.

    Abstract: An adaptor and an assembly including a cylinder and the adaptor are provided. The adaptor is used to mount the cylinder to a fluid channel. The adaptor is formed of a unitary wall including a first portion adapted to mount to the fluid channel, a second portion adapted to be engaged with a tool extending from the first portion, and a third portion extending from the second portion and seated within an inlet passageway of the cylinder. The third portion includes locking features for locking the adaptor to the cylinder, and a sealing feature for sealing the adaptor to the cylinder. The sealing feature is distal to the second portion such that when a torque is applied to the adaptor, the sealing feature does not cause the adaptor to shear. The cylinder and fluid channel may be capable of being swiveled relative to each other around the adaptor, such swiveling may be up to 360 degrees and may be 360 degrees.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.
