Variable flow poppet valve

A nozzle for dispensing fluid, the nozzle comprising:

• a nozzle body defining an upstream fluid chamber and a downstream fluid chamber;
• an outer valve seat extending radially inward from the nozzle body between the upstream fluid chamber and the downstream fluid chamber;
• a variable flow valve disposed within the nozzle body, the variable flow valve movable between a fully closed position, a partially open position, and a fully open position, wherein the variable flow valve comprises:
• an outer valve plug comprising:
• a valve plug body having an upstream portion and an outer plug tapered portion extending from the upstream portion and configured to mate with the outer valve seat;
• and
• a plug passage extending through the valve plug body and including a first stage seat;
• a second stage spring disposed within the upstream fluid chamber and configured to bias the outer valve plug towards the outer valve seat;
• a bushing disposed within the plug passage;
• an inner valve plug disposed within the plug passage and extending into the bushing, the inner valve plug comprising:
• a head having an inner plug tapered portion, the inner plug tapered portion configured to mate with the first stage seat;
• and
• a shaft extending from the head and into the bushing;
• a cap attached to the shaft and disposed within the bushing;
• and
• a first stage spring disposed within the bushing and around the shaft, the first stage spring extending between an upstream end of the bushing and the cap;
• wherein the cap is configured to actuate the variable flow valve from the fully closed position to the partially open position, where the inner valve plug is displaced from the first stage seat, and from the partially open position to the fully open position, where the outer valve plug is displaced from the outer valve seat.
