VIBRATION ELIMINATOR FOR PRESSURE
REGULATORS

My invention relates to air, gas, water, steam
and oil pressure regulators, and has among its
objects and advantages the provision of an im
proved vibration eliminator.
In the accompanying drawing:

of a conventional pressure regulator embodying
my invention.

To the
outer ends of the stems 56 are pivotally connected
eccentrics 58, all the eccentrics being of the same
size, weight and shape. The eccentrics are ar
ranged at right angles to their respective stems
56, and the pivotal connection between the ec
centrics and the stems are located at the ends of
the eccentrics.
Each eccentric includes a curvature 60 engag
