摘要： A mounting for a pressure indicating gauge in which gas pressure pulsations from a source of gas pressure are absorbed by a helical tubular spring conveying the pressurized gas serially to a chamber at one side of a diffusion plate through which the gases are delivered to break up into separate pressure waves. The gases enter a cavity at the opposite side of the diffusion plate and pass to the gauge which mechanically moves an indicator which is further dampened to avoid residual pressure pulsations. The mounting serves also to absorb vibrations which cause erratic oscillation of the gauge indicating pointer and also serves to isolate the gauge from shocks. The mounting further includes a soft, rubber-like sleeve which engages the outer surfaces of the tubular spring to dampen its vertical movement and prevent swaying of the gauge relative to the structure on which it is mounted. The gauge mounting further includes a ballast member to lower the center of gravity of the suspended mass and may employ an auxiliary spring to support heavier gauges.
