    Abstract: A pressure accumulator for a hydraulic system includes a rigid container whose cavity contains a partition of pliable, resilient material which seals one compartment adjacent the bottom wall of the container from another compartment containing a gas under a pressure sufficient for expanding the partition into abutting engagement with the bottom wall when the fluid pressure in the one compartment equals atmospheric pressure. A passage outward from the one compartment through the bottom wall is shielded against insertion therein of any portion of the partition, and the resulting risk of injury to the partition, by a shielding member projecting from the bottom wall into the one compartment and having a frontal surface directed toward the other compartment. Its annular rim portion has a surface contiguously adjacent an annular portion of the bottom wall, and the two annular surface portions and the partition bound therebetween an annular space at atmospheric pressure in the one compartment. The passage of the bottom wall communicates with an orifice in the annular space.

    Abstract: A method of forming a pressure accumulator is disclosed which comprises the steps of advancing a cylindrical resilient metallic sleeve carrying a separator or bladder through the open mouth of a shell forming a part of the casing of the accumulator, the shell including on an inner wall surface thereof an annular groove defining an inwardly directed sharpened lip in the casing wall. The sleeve is positioned such that the outer circumference thereof, adjacent its upper end, is disposed in abutting relation to the said lip. An electrode is placed against the upper end of the sleeve opposite the lip at a position remote from the deformable bladder. The shell section and the electrode are relatively rotated about an axis of revolution coincident with the longitudinal axis of the shell while electrical current is passed through the electrode, sleeve, and into the casing, the current flow being sufficient to induce a melting and consequent fusion between components of the metal forming the sleeve and lip portion, whereby the sleeve is secured to the shell section and a seal is defined by the annular fused portions of the shell and the sleeve. Thereafter the open mouth portions of the shells are welded together to define a completed casing.

    Abstract: This invention relates to a hydro-pneumatic pressure reservoir of the type comprising a hollow container having a gas port and an oil port, with a deformable partition intervening therebetween defining a gas chamber and an oil chamber. A magnetic switch is mounted externally of the container, and actuating means internally of the container causes actuation of said magnetic switch to give an alarm signal when the volume of gas in the gas chamber falls below a predetermined amount.

    Abstract: An accumulator for a liquid pressure system has a hollow casing comprising two hollow casing parts having mating cylindrical surfaces. There is an annular groove in each cylindrical surface, the two grooves being aligned to define an annular cavity in which is/are housed one or more inserts. The insert(s) act to hold the two hollow casing parts together. The hollow casing is assembled by inserting one of the mating cylindrical surfaces within the other to define the annular cavity, and inserting the one or more inserts through a hole in the wall portion of the outer mating casing part into the annular cavity. An annular cover maybe placed over the wall portion of the outer mating casing part when the two casing parts are assembled together, so as to cover the radially outer end of the hole.
