摘要： The purpose of the present invention is to provide a metal bellows-type accumulator in which reduced durability due to a metal bellows (2) vibrating in the radial direction and contacting the inner circumferential surface of an outer shell (1) does not occur. To achieve said purpose, the bellows-type accumulator is provided with: an outer shell (1), on one end of which a pressure-introducing passage (C) is opened; and a metal bellows (2) which comprises ridges (211) facing radially outward and troughs (212) facing inward formed in a repeating pattern, is capable of expanding and contracting in the axial direction, and which partitions the inner chamber of the outer shell (1) into a pressure introduction chamber (A) that is in communication with the pressure-introducing passage (C) and a gas chamber (B) in which a cushioning gas is sealed. The area in the metal bellows (2) where the amplitude of radial direction vibration is maximal is provided with a cylindrical section (213) that has a larger diameter than the maximum diameter of the various ridges (211) and is capable of contacting the inner circumferential surface of the outer shell (1) with a prescribed width in the axial direction.

摘要： A method and apparatus for reducing undesirable pressure fluctuations over predetermined pressure and frequency ranges in a working fluid system, facilitating maintenance of appropriate levels of stored energy in the fluid system. Embodiments may be employed within a fluid system to dampen pressure fluctuations over an adequately large pressure range, for example in a resonant vibratory system. In such systems, pressures vary dramatically depending on whether resonance is achieved. An apparatus comprises a pressure vessel having a self equilibrating flexible piston device (104). The piston separates a gas volume (115) from a fluid volume (120) exposed to the system flow. The piston translates within the pressure vessel to equilibrate the gas and fluid pressures. A flexible portion (108) of the piston deflects at high frequency and adequate volume to reduce undesirable pressure fluctuations. The flexible portion translates force via its outer periphery to a ring portion (106) which translates within the pressure vessel.

摘要： A pressure store comprising sub-chambers (8, 54, 28) arranged in a housing (2), a first sub-chamber (8) arranged between the housing (2) and a flexible separating diaphragm (40), a second sub-chamber (54) arranged between the separating diaphragm (40) and a supporting body (48), and a third sub-chamber (28) encompassed by the supporting body (48), wherein the first sub-chamber (8) can be filled with a first fluid, wherein the second sub-chamber (54) and the third sub-chamber (28) are connected to one another in fluid-conducting fashion and can be filled with a second fluid, and wherein the first and the second sub-chamber (8, 54) vary in terms of their respective sizes as a result of movements of the separating diaphragm (40) as a function of the respective filling state, is characterized in that the first fluid is a storage medium and the second fluid is a working medium, and in that the second sub-chamber (54) is increased in size during the extraction of storage medium from the pressure store and is reduced in size during the filling of the pressure store with storage medium.

摘要： The invention relates to a structural component in the form of a parting element (10) which extends in two different main directions (12,13), is of at least single-layer design and is elastically flexible, which parting element (10) has at least two linear structural parts (18) which are arranged offset with respect to one another in the two main directions (12,13). As a result of at least a part of the linear structural parts (18) having a loop-shaped cross section and as a result of the parting element (10) being formed at least partially from a substance which has a fluoroplastic material, preferably a substance composed entirely of fluoroplastic material, a structural component is obtained which is characterized not only by excellent diffusion impermeability but also by particularly good mechanical properties such as extreme bending fatigue strength.
