用于降低流动噪声的装置
摘要：
本发明涉及一种用于降低流动噪声的装置(1、1'、1”)，其包括：第一连接件(2、2')；背离第一连接件(2、2')的第二连接件(3、3')；布置在第一连接件(2、2')和第二连接件(3、3')之间的外套管(4、4')；以及布置在连接件(2、2'、3、3')之间的内套管(5、5')，其中，通过至少一个周向延伸的径向套环(6、6')彼此分离的至少两个容积室(7、7'、8、8'、9、9'、10、10')布置在内套管(5、5')和外套管(4、4')之间，所述容积室借助于内套管(5、5')的壁(12、12')中的开口(11、11')连接到由内套管(5、5')包围的管线空间(13、13')，其中，径向套环(6、6')在径向套环的自由端(14、14')处具有密封圈(15、15'、15”)。本发明的特征在于，密封圈(15、15'、15”)被设计为环形帽，所述环形帽延伸到套环(6、6')的上方，并且借助于环形帽的周向延伸的外侧表面(21、21”)以密封的方式贴靠在与所述套环(6、6')的自由端(14、14')相邻的套管(4、4'、5、5')的壁表面(22、35)上，并且借助于密封圈的背离外侧表面(21、21”)的内侧表面(23、23”)以密封的方式贴靠在套环(6、6')的自由端(14、14')的端面(25、25')上，或者借助于平行于径向套环(6、6')延伸的环形径向接触表面(26、26')以密封的方式贴靠在套环(6、6')的面对环形帽的侧表面(28)上。
摘要（英）：

The invention relates to a device (1, 1', 1'') for lowering flow noises, comprising a first connection piece (2, 2'), a second connection piece (3, 3') facing away from the first connection piece (2,2'), an outer sleeve (4, 4') arranged between the first connection piece (2, 2') and the second connection piece (3, 3'), and an inner sleeve (5, 5') arranged between the connection pieces (2, 2', 3,3'), wherein at least two volume chambers (7, 7', 8, 8', 9, 9', 10, 10') separated from each other by at least one peripherally extending radial collar (6, 6') are arranged between the inner sleeve (5, 5') and the outer sleeve (4, 4'), and are connected to the line space (13, 13') enclosed by the inner sleeve (5, 5') by means of openings (11, 11') in the wall (12, 12') of the inner sleeve (5, 5'),wherein the radial collar (6, 6') has a sealing ring (15, 15', 15'') at the free end (14, 14') of the radial collar. The invention is characterized in that the sealing ring (15, 15', 15'') is designed as a ring cap, which reaches over the collar (6, 6') and lies against a wall surface (22, 35) of the sleeve (4, 4', 5, 5') adjacent to the free end (14, 14') of the collar (6, 6') in a sealing manner by means of a peripherally extending outer lateral surface (21, 21'') of the ring cap and against the end face (25, 25') of the free end (14, 14') of the collar (6, 6') in a sealing manner by meansof the inner lateral surface (23, 23'') of the sealing ring facing away from the outer lateral surface (21, 21'') or lies against the side surface (28) of the collar (6, 6') facing the ring cap in a sealing manner by means of an annular radial contact surface (26, 26'') extending parallel to the radial collar (6, 6').
