Abstract:
1. A surge suppressor/shut-off valve apparatus, comprising: a valve body; said valve body having an inlet port and an outlet port; a poppet member slidably disposed within said valve body; wherein said poppet member has a base portion slidingly engaging said valve body; a recess defined in said base portion; openings defined in said base portion; a valve seat positioned within said valve body; a biasing member positioned within said valve body; a shaft or neck portion centrally disposed on said base portion; and a valve seat interface portion on said shaft or neck portion adapted to interface with said valve seat; wherein movement of said poppet member within said valve body will reduce the flow rate of a fluidic material between said inlet and outlet ports from a first, nominal flow rate, to a second, reduced flow rate, when a pressure differential between said inlet and outlet ports is exceeded; wherein said biasing member urges said poppet member away from said valve seat for flow at said first flow rate; wherein said first flow rate occurs when said poppet member is fully biased away from said valve seat; wherein said second reduced flow rate is maintained until said pressure differential is no longer exceeded; and wherein said poppet member further comprises a bypass port that allows said second reduced flow rate of a fluidic material when said poppet member is seated on said valve seat.
