Abstract

The invention refers to an arrangement of a valve and a pressure vessel. The valve has a housing with at least an opening, a plunger slideably positioned in the housing, a control mechanism to cause plunger movement. The pressure vessel has an exterior surface with at least an opening. The valve is connected to the at least an opening of the pressure vessel. The plunger has at least a first part with a larger size and a second part with a smaller size. The first part of the plunger is positioned outside of the pressure vessel in all valve configurations.

Claims

1. An arrangement of a valve and a pressure vessel, wherein

the valve has

a housing with at least an opening,

a plunger slideably positioned in the housing,

a control mechanism to cause plunger movement,

the pressure vessel has an exterior surface with at least an opening,

wherein

the valve is connected to the at least an opening of the pressure vessel,

the plunger has at least a first part with a larger size and a second part with a smaller size,

characterized in that

the first part of the plunger is positioned outside of the pressure vessel in all valve configurations.

2. The arrangement of claim 1, characterized in that

the housing includes a base,

a nozzle pipe is arranged in the pressure vessel;

the base is connected to the nozzle pipe.

3. The arrangement of claim 2, characterized in that the base extends from the housing.

4. The arrangement of claim 2, characterized in that the base is tubular and sized to threadedly engage an interior surface of the nozzle pipe.

5. The arrangement of claim 1, characterized in that the housing further comprises a dampening mechanism to reduce impact and reduce impact noise between the housing and the plunger upon movement of the plunger into the open position.

6. The arrangement of claim 1, characterized in that the control mechanism comprises a valve on the housing for control of fluid flow to and from the housing.

7. A valve having

a housing with at least an opening,

a plunger slideably positioned in the housing,

a control mechanism to cause plunger movement,

wherein

the plunger has at least a first part with a larger size and a second part with a smaller size,

the housing has a cavity with a first cavity part of larger size and a second cavity part of smaller size,

the housing has a first outer part with larger size and a second outer part with smaller size,

characterized in that

the first cavity part is completely included in the first outer part of the housing.

8. The valve of claim 7, characterized in that the plunger is slideably positioned in the first cavity part of the housing.

9. The valve of claim 7, characterized in that the second part of the plunger is configured for entering the second cavity part of the housing.

10. The valve of claim 7, characterized by further comprising a base, which extends from the housing.
