摘要： The invention relates to a silencer (1) for noise-laden gas pipes, especially for a suction pipe and/or an exhaust pipe of an internal combustion engine, comprising an outer pipe (2) with an inlet side (3) and an outlet side (4), a plurality of diaphragm rings (9, 9′, 9″, ′″, 9″″) each with an outer surface connected (5) to the inner surface of the outer pipe (2), at least one insert (6) with an outer surface connected (7) to the inner surface of the outer pipe (2) and/or the diaphragm rings (9, 9′, 9″, 9′″, 9″″) and with a plurality of openings (8) which are closed on one side. Said insert (6) forms sub-pipes for the gas flow in the silencer, and the openings (8), which are closed on one side, open into the sub-pipes, the depth thereof being /4 in relation to the wavelength of a frequency to be silenced. At least one perforated wall (10, 10′, 11, 11′), extends between at least two diaphragm rings (9, 9′, 9″, 9′″, 9″″) whereby an outer surface is connected (7) to at least one inner surface of the two diaphragm rings (9, 9′, 9′″, 9″″, wherein at least one resonance cell is fixed between the two diaphragm rings (9, 9′, 9″, 9′″, 9″″) of the perforated wall (10, 10′, 11, 11′) and the outer pipe (2).

摘要： The broadband surface-like absorber of the invention is used, in particular, for absorbing troublesome airborne noise in the acoustic frequency range. The broadband surface-like absorber, which operates on the Helmholtz resonator principle, is distinguished by a checkerwork of irregular construction, the webs of which are aligned with their narrow sides perpendicular to the principal surface of the perforated plate and the side edges of which are connected in a sound-pressure-resistant and fluidtight manner on the sound side to the rear side of the perforated plate and, on the rear side, to an extended-area cavity boundary aligned with the same orientation as the perforated plate to form differently tuned chamber resonators.

摘要： A pumped-storage power plant may include a working cylinder partially submerged in a working fluid reservoir having an upper fluid compartment above a fluid level of the working fluid reservoir and a lower fluid compartment below the fluid level, a buoyant piston movably guided in the direction of gravity relative to the working cylinder and which seals off the upper fluid compartment such that a gravitationally induced exchange of fluid between the upper and the lower fluid compartment is prevented. The plant may operate in an energy charging mode where working fluid is introduced into the upper fluid compartment so that the buoyant piston is submerged in the lower fluid compartment, and an energy delivery mode where upper fluid is pressed out of the upper fluid compartment and/or a fluid column of the upper fluid built up during the energy charging mode is discharged from the upper fluid compartment.
