Patent number: 10900358Abstract: The packaged compressor includes: an exhaust duct having an exhaust port; a gas cooler arranged to be inclined with respect to the exhaust port in the exhaust duct; and at least one sound insulating plate arranged in a direction perpendicular to the exhaust port in the exhaust duct, the sound insulating plate configured to partition the exhaust port. In the packaged compressor, the exhaust port is partitioned into divided openings by the sound insulating plate. Of the divided openings, an area of a first divided opening provided on a side where a distance between the gas cooler and the exhaust port is shortest is larger than an area of a second divided opening.Type: GrantFiled: May 25, 2017Date of Patent: January 26, 2021Assignee: Kabushiki Kaisha Kobe Seiko ShoInventors: Yoshio Yano, Suguru Kiuchi

Patent number: 10403257Abstract: A sound deadening device has an introducing and damping section. The introducing and damping section includes an introduction section that introduces fluid, an expansion chamber, and a lead-out section. The expansion chamber is communicated with the introduction section, has a flow passage cross-section larger than a flow passage cross-section of the introduction section, and has protrusions along a travelling direction of a sound wave, resonance of the sound wave being to be suppressed. The lead-out section is communicated with the expansion chamber, has a flow passage cross-section smaller than that of the expansion chamber, and leads out the fluid in a direction different from an introduction direction of the fluid. Accordingly, it is possible to weaken the resonance of the sound wave, suppress rise of inner sound pressure of the sound deadening device, and prevent reduction in a sound deadening effect.Type: GrantFiled: January 4, 2016Date of Patent: September 3, 2019Assignee: Kobe Steel, Ltd.Inventors: Masahiro Kikuchi, Kazuki Tsugihashi, Yosuke Fukushima, Kazuya Hirata, Suguru Kiuchi

Patent number: 10174655Abstract: A silencer includes: a housing that has a draw-in portion drawing in fluid, and a plurality of sound attenuating portions arranged in a flowing direction of the fluid; a first partition provided with an intermediate communicating portion communicating the most downstream attenuating portion with the adjacent attenuating portion located adjacent to the most downstream attenuating portion; a valve portion disposed in the most downstream attenuating portion, the valve portion being capable of closing the intermediate communicating portion; a valve holding portion holding the valve portion, the valve holding portion being detachably attached to the housing; and a draw-out portion provided in a portion of the most downstream attenuating portion other than the valve holding portion, the draw-out portion drawing out the fluid from the most downstream attenuating portion.Type: GrantFiled: May 19, 2015Date of Patent: January 8, 2019Assignee: Kobe Steel, Ltd.Inventors: Masahiro Kikuchi, Kazuki Tsugihashi, Yosuke Fukushima, Kazuya Hirata, Suguru Kiuchi
