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.

First claim

The invention claimed is:

1. An arrangement of a valve and a pressure vessel, comprising:
the valve comprising a housing with at least an opening, a plunger comprising at least a first part with a larger size and a second part with a smaller size, slideably positioned in the housing, and a control mechanism comprising an interior vault defined by a wall extending interiorly within the housing from a top of the housing and distanced from interior surfaces of sides of the housing, and a center plug portion slideably arranged within the interior vault to cause plunger movement, connected to at least an opening of the pressure vessel; and
the pressure vessel with an interior area of compressed air inside the pressure vessel, wherein when the valve connected to the pressure vessel is in a closed position, the at least a first part with a larger size of the plunger is positioned outside of the at least an opening and the interior area of the pressure vessel, and the second part with a smaller size extends beyond the at least an opening of the pressure vessel into the interior area of the pressure vessel.

2. The arrangement of claim 1 , wherein the housing includes a base, and the pressure vessel includes a nozzle pipe arranged within the pressure vessel connected to the base of the housing.

3. The arrangement of claim 2 , wherein the base extends from the housing.

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

5. The arrangement of claim 1 , wherein the housing further comprises a cushion dampening mechanism to reduce impact and reduce impact noise between the housing and the plunger upon movement of the plunger into an open position within the housing.

6. The arrangement of claim 1 , wherein the control mechanism further comprises a control valve on the housing for control of a fluid flow to and from the interior vault of the housing.

7. The arrangement of claim 1 , wherein the plug portion is centered within the plunger.

8. The arrangement of claim 1 , wherein the plug portion is in slideable contact with a sealing seat.

9. A valve comprising:
a housing with a first outer part with larger size, a second outer part with smaller size, a cavity with a first cavity part of larger size and a second cavity part of smaller size, with the first cavity part completely included in the first outer part of the housing, and at least an opening;
a plunger with at least a first part with a larger size and a second part with a smaller size slideably positioned in the housing; and
a control mechanism comprising an interior vault within the first cavity part of the cavity defined by a wall extending interiorly within the housing from a top of the housing and distanced from interior surfaces of sides of the housing, and a plug portion extending from a cylinder portion of the second part of the plunger slideably arranged within the interior vault, a sealing seat and a control valve to cause plunger movement.

10. The valve of claim 9 , wherein the plunger is slideably positioned in at least the first cavity part of the housing.

11. The valve of claim 9 , wherein the second part of the plunger is configured for entering the second cavity part of the housing.

12. The valve of claim 9 , further comprising a base, which extends from the housing.

13. The valve of claim 9 , further comprising a tubular base sized to threadedly engage an interior surface of a nozzle pipe.

14. The valve of claim 9 , wherein the housing further comprises a cushion dampening mechanism to reduce impact and reduce impact noise between the housing and the plunger upon movement of the plunger into an open position within the housing.

15. The valve of claim 9 , wherein the control valve controls a fluid flow to and from the interior vault of the housing.
