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, 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.
