Abstract:
In a pressure gauge including a fluid inlet at which to receive fluid of which the value of pressure is to be monitored, a pressure sensitive element responsive to changes in pressure values of the fluid received at said inlet and an indicator supported on an arcuately displaceable shaft and operative by said pressure sensitive element for providing indicia of the value of pressure being received, a dampener for suppressing undesirable vibration force in the received fluid from being transmitted to said indicator, said dampener being contained in an open relation within said gauge and comprising:a body supported on said indicator shaft for displacement therewith and positioned opposite a juxtaposed substantially fixed surface thereat; anda packing of lubricant of predetermined viscosity positioned selectively intervening at least between said body and said contiguously juxtaposed substantially fixed surface for effecting a thin cushioning layer of lubricant therebetween.
