    Abstract: A hydraulic hammer is disclosed that includes at least one accumulator that is connectable to a hydraulic circuit disposed in the housing of the hammer. The accumulator includes an annular base coupled to a cover with a diaphragm sandwiched therebetween. The annular base includes a proximal end and a distal end. The proximal end of the annular base defines a first central opening. The proximal end of the base in the housing define an annular inlet that encircles the first central opening and that is in communication with the first central opening. The cover also includes a proximal end and a distal end. The proximal end of the cover is coupled to the distal end of the base with the outer periphery of the diaphragm sandwiched therebetween.

    Abstract: A hydroaccumulator, in particular a bladder accumulator, includes a pressurized container (1) and a separation element (5) located in the container to separate a gas chamber (7) lying adjacent to an inlet on the gas side from a fluid chamber (9) lying adjacent to an inlet on the fluid side inlet (3), having a fluid connecting sleeve (11) and a valve arrangement located in the connecting sleeve (11). The valve body (17) has a transversal bore (33). The valve body is pretensioned in an open position which allows the passage of fluid and can be displaced into a closed position by a displacement of the separation element (5). The interior surface (15) of the connecting sleeve (11) lies directly against the valve body (17) and guides the displacement of the body between the open and closed positions. The side of the valve body (17′) that faces the separation element (5) is configured as a planar plate extending partially into the fluid chamber (9). The diameter of the valve body (17) is greater than its height, measured in the direction of displacement of the valve body (17). The valve arrangement has a plate-valve construction of small proportions and can be cost-effectively produced.

    Abstract: The invention concerns a pressure tank comprising a rigid casing having opposite first and second orifices, and an elastically deformable separator extending inside the casing between the two orifices and subdividing the inside volume of the casing into variable-volume first and second compartments. The second compartment communicates with a hydraulic circuit via the second orifice. The first compartment is filled with elastically deformable solid elements, and the resulting assembly behaves like a spring. In the non-compressed state, the overall volume of the elastically deformable solid elements is substantially equal to the volume of the first compartment when the separator is at rest.

    Abstract: In an in-line type accumulator of the type that on the inside of a pressure vessel there are provided a cylindrical isolating member and an inner tube having communication holes in succession in a concentric manner, a diameter of a central portion of the isolating member is made larger than a diameter of the portions on the opposite sides of the central portion, and thereby constricted portions having a U-shaped longitudinal cross-section are formed on the opposite sides of the central portion.

    Abstract: An accumulator comprises a pressure vessel having a detaining step, a bladder inserted therein and provided with a flange, and a threaded plug to close the opening of said pressure vessel, said threaded plug having a downward projection to be inserted into the inner side of the opening of the bladder, and said projection and said opening of the bladder each being provided with a tapered or similarly curved periphery which is tightly to contact together at the final moment of screwing down the plug while to provide a clearance between them at the stage other than that moment so as the bladder not to be forced to turn by the rotation of the plug.

    Abstract: A liquid pressure tank is provided for storing liquid under pressure for use in domestic or commercial reticulated supply of the type having an impervious diaphragm dividing the tank into an air chamber and a liquid chamber, a constant amount of air being maintained in the chamber under pressure. A liquid pump and pressure switch system is provided for maintaining liquid in the chamber between preset pressure limits, the diaphragm being so configured and secured to form a pistonlike portion within the tank which reciprocates under variation of liquid pressure to minimize wrinkling or stretching of the diaphragm. Also a fixed plate can be arranged over the liquid outlet as protection from rupturing of the diaphragm at low liquid levels.
