    摘要: An accumulator (ACC) in which a container main body (1) and a closure member (5) are screw-joined together. A reverse-buttress internal thread or an internal thread having an included angle of 90 degrees is used as an internal thread of the screw-joined portion. The reverse-buttress internal thread is formed in such a way that the inclination angle (β) of a clearance flank of the buttress internal thread is the inclination angle (β) of a reverse pressure flank (20A) receiving a load, the inclination angle (θ) of a pressure flank is the inclination angle (θ) of a reverse clearance flank (2B). The internal thread having an included angle of 90 degrees is formed in such a way that inclination angles (α),(γ) of both flanks are equal and the included angle (δ) is about 90 degrees.

    摘要: The invention relates to a fluid power accumulator in which the fluid undergoes a state change as the system is pressurized to store energy. A state change can be a phase change, a chemical reaction, or a combination of these. Generally the state change results from the interaction of a compressible fluid contained in the accumulator with another substance, which can be a fluid or a solid. Preferably, the state change includes the physical adsorption of a fluid by a solid adsorbant. The invention can improve the energy storage density of a fluid power accumulator, allow a given energy storage density to be achieved at a lower maximum pressure, facilitate heat transfer and storage within an accumulator, and/or improve accumulator efficiency by storing energy in a form other than thermal energy, such as in the form of chemical energy.

    摘要: A hydraulic accumulator of the liquid-gas type, comprising a housing (11) defining a chamber (11C), a gas port (30) and a liquid port (19). A gas charging valve (31) is disposed in the gas port (30) to control admission of high pressure gas. A semi-permeable separator (35) is disposed within the housing (11) to separate the internal chamber (11C) into a gas chamber (33) in communication with the gas port (30), and a liquid chamber (21) in communication with the liquid port. A means (41) is within the liquid chamber for collecting gas which passes from the gas chamber (33), through the semi-permeable separator, and into the liquid chamber. Included is a conduit (45) having one end (45a) in communication with the gas collecting means (41), and another end (45b) operably associated with the housing (11,27) to communicate gas from the collecting means (41) out of the liquid chamber.

    摘要: The invention relates to a hydraulic reservoir in particular a membrane reservoir, with a gas inlet body (12) which may be connected to parts of the reservoir housing and which comprises at least one mounting surface (28) for an elastically flexible separating element (16), which separates two chambers arranged within the reservoir housing from each other. The separating element (16) comprises a edge reinforcement (30) formed by material thickening to give a fixing edge for that part with the corresponding mounting surface (28) of the gas inlet body (12). Failures at the position of the fixing of the separation element to the hydraulic reservoir are avoided, despite high loading of the separating element under working conditions for the reservoir, whereby the edge reinforcement (30) is provided with a convex guide surface on the side thereof facing the gas inlet body (12) in contact with the corresponding mounting surface (28), which is at least partly concave in embodiment to match said unit.

    摘要: A hydraulic accumulator, especially a bladder accumulator, includes an accumulator housing (10), and a separation element disposed in and separating the accumulator housing interior into a gas chamber (16) adjoining an inlet (14) on the gas side from a fluid chamber (18) adjoining an inlet (20) on the fluid side. The inlet on the fluid side has a fluid connecting neck (22) having a valve support (40) disposed in the neck. The valve support has fluid openings (42), and a disk-shaped valve body (32) that tapers towards the valve shaft (46) on its side facing the valve support (40). The valve shaft can be pretensioned via a force accumulator (62) into the open position releasing the fluid opening, can be displaced into its closed position by a displacement of the separation element (12), and projects into the fluid chamber (18) in the open position. The valve body (32) is an integral, especially one-piece, component of the valve support (40) that is guided along its outer periphery (56) within the connecting neck (22) so as to be displaceable in it, creating a hydraulic accumulator that is comparatively simple and inexpensive in production.
