Abstract

A valve for pressurized fluid having a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit having a collection of valve shutter(s) having at least one shutoff valve shutter allowing the circuit to be closed or opened, the valve having a member for manually controlling the collection of valve shutter(s), the control member being mounted with the ability to move on the body between a rest position in which the collection of valve shutter(s) is in a position in which the circuit is closed and an active position in which the control member actuates the collection of valve shutter(s) into a position in which the circuit is open with a first bore section.

First claim

The invention claimed is:

1. A valve for pressurized fluid comprising a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit comprising a collection of valve shutters comprising at least two shutoff valve shutters allowing the circuit to be closed or opened, the valve comprising a control member for manually controlling the collection of valve shutters, the control member being mounted with the ability to move on the body between a rest position in which the collection of valve shutters is in a position in which the circuit is closed and an active position in which the control member actuates the collection of valve shutters into a position in which the circuit is open with a first bore section, the valve comprising a mechanism for locking the control member in the rest position, the locking mechanism comprising a manual actuator mounted with the ability to move on the body between a locked first position that locks the control member to prevent movement moving from the rest position toward the active position, and a second position in which the control member is unlocked allowing movement from the rest position toward the active position, in the unlocked second position, the manual actuator placing the collection of valve shutters in a position in which the circuit is open to a second bore section, further comprising a return member returning the manual actuator toward the locked first position.

2. The valve as claimed in claim 1 , wherein the second bore section is smaller than the first bore section.

3. The valve as claimed in claim 1 , wherein the manual actuator comprises at least one of the following: a lever articulated to the body, a push-button to be moved in translation, a rotary actuator such as a handwheel or a knob.

4. The valve as claimed in claim 1 , wherein the control member comprises at least one of the following: a lever articulated to the body, a push-button to be moved in translation, a rotary actuator such as a handwheel or a knob.

5. The valve as claimed in claim 1 , wherein the movement of the control member from the rest position toward the active position describes a movement of the same nature as the movement of the manual actuator moving from the locked first position toward the unlocked second position.

6. The valve as claimed in claim 1 , wherein the movement of the control member from the rest position toward the active position describes a movement of a different nature or in a distinct direction compared with the movement of the manual actuator moving from the locked first position toward the unlocked second position.

7. The valve as claimed in claim 1 , further comprising a coupling mechanism that couples the movement of the control member and of the manual actuator when the control member is moved from the active position toward the rest position and/or from the rest position toward the active position, the coupling mechanism automatically moving the manual actuator when the control member is moved.

8. The valve as claimed in claim 1 , wherein the collection of valve shutters comprises two distinct shut-off valve shutters able to move with respect to respective seats and in the open position respectively defining the two distinct bore sections, the two valve shutters being controlled by the control member and by the manual actuator, respectively.

9. The valve as claimed in claim 8 , wherein the two distinct shut-off valve shutters are arranged in series in the one same line of the circuit.

10. The valve as claimed in claim 9 , wherein the two shutoff valve shutters are controlled by at least one same mobile pushrod controlled by the control member and by the manual actuator.

11. The valve as claimed in claim 1 , wherein the locking mechanism for locking the control member in the rest position comprises a mobile mechanical stop.

12. The valve as claimed in claim 1 , wherein the control member is a lever articulated to the body.

13. The valve as claimed in claim 12 , wherein the locking mechanism for locking the control member in the rest position acts on a cam attached to the lever.

14. The valve as claimed in claim 13 , wherein the locking mechanism that locks the control member in the rest position comprises a mechanical stop between a profile of the cam of the control member and a mobile member of a mechanism transmitting movement between the cam) and the collection of valve shutters.

15. The valve as claimed in claim 1 , wherein the manual actuator is a lever articulated to the body.

16. A reservoir or collection of reservoirs for pressurized fluid, comprising a valve as claimed in claim 1 .
