gauge. A pressure gauge snubber is therefore
installed in the line that leads to the pressure
gauge.
The purpose of the snubber is to dampen the
oscillations and thus provide a steady reading and
protection for the gauge. The basic components
of a snubber are the housing, fitting assembly with
a fixed orifice diameter, and a pin and plunger
assembly (fig. 8-16). The snubbing action is
obtained by metering fluid through the snubber.
The fitting assembly orifice restricts the amount
of fluid that flows to the gauge, thereby snubbing
the force of a pressure surge. The pin is pushed
and pulled through the orifice of the fitting
assembly by the plunger, keeping it clean and at
a uniform size.
