气压振动阻尼装置
摘要：
本发明涉及气压振动阻尼装置。具体而言，一种具有气压振动阻尼装置的气流阀(32)，该气压振动阻尼装置用以减小由气体穿过气阀的流动所产生的振动。气阀包括终止于排出开口(56)处的气流导管(18)。阀部件(50)相对于排出开口可动地定位，且在流动状态下容许气体流动而在就座位置阻止气体流动。阀部件包括形成在阀部件内的气体通路(62)。至少一个柔性膜(70)安装到阀部件(50)上且包绕气体通路的出口开口(66)。当气流导管(18)内的气流增加时，柔性膜(70)充气，使得柔性膜接触稳定导管(78)的内表面(76)。柔性膜与稳定导管(78)之间的相互作用减小了由气体穿过阀部件的流动所产生的振动。
摘要（英）：

The invention relates to a pneumatic vibration dampening device. Concretely, a gas flow valve (32) having pneumatic vibration dampening device to reduce the vibrations created by the flow of gas through the gas valve (32). The gas valve (32) includes a gas flow conduit (18) that terminates at a discharge opening (56). A valve member (50) is movably positioned relative to the discharge opening (56) and allows gas flow in a flow condition and prevents the flow of gas in a seated position. The valve member (50) includes a gas passage (62) formed within the valve member (50). At least one flexible membrane (70) is mounted to the valve member (50) and surrounds an outlet opening (66) of the gas passage (62). The flexible membrane (70) is inflated as the flow of gas within the gas flow conduit (18) increases such that the flexible membrane (70) contacts an inner surface (76) of a stabilizing conduit (78). The interaction between the flexible membrane and the stabilizing conduit (78) reduces the vibrations created by the flow of gas past the valve member.
