Abstract
A fluid supply package comprising a pressure-regulated fluid storage and dispensing vessel, a valve head adapted for dispensing of fluid from the vessel, and an anti-pressure spike assembly adapted to combat pressure spiking in flow of fluid at inception of fluid dispensing.

1-20. (canceled)
A pressure regulator comprising:
- a housing having a chamber with an inlet and an outlet, the chamber including therein a pressure-sensing assembly with a stationary portion fixed relative to the housing and a movable portion, the stationary and movable portions being interconnected by a bellows structure with diaphragm elements adapted to expand and contract in response to pressure variations in the chamber;
- a damper assembly adapted to dampen oscillations and stabilize movement of the pressure-sensing assembly between open and closed positions, the damper assembly disposed within a sleeve formed on the movable portion;
- and
- a poppet closure assembly operatively coupled to the pressure-sensing assembly and adapted to regulate fluid pressure between the inlet and outlet of the chamber, the poppet closure assembly including a poppet element and a seating structure located at the inlet of the chamber, the poppet element having an upper spherical shaped surface adapted to mate and contact the seating structure to thereby form a seal with the poppet element.

- a damper assembly adapted to dampen oscillations and stabilize movement of the pressure-sensing assembly between open and closed positions, the damper assembly disposed within a sleeve formed on the movable portion;
- and
- a poppet closure assembly operatively coupled to the pressure-sensing assembly and adapted to regulate fluid pressure between the inlet and outlet of the chamber, the poppet closure assembly including a poppet element and a seating structure located at the inlet of the chamber, the poppet element configured to contact the seating structure to form a seal.
