Abstract

A valve assembly is provided with a first valve body provided with a first chamber; a shutter, which is movable in the first chamber and is connected to a control device; a second valve body, coupled to the first valve body and provided with a second chamber communicating with the first chamber; a check valve, at least partially housed in the second chamber; at least a first fitting, mechanically coupled to the second valve body; the second valve body and the first fitting being distinct pieces.

Claims

1. A valve assembly comprising:

a first valve body provided with a first chamber;

a shutter, which is movable in the first chamber and is connected to a control device;

a second valve body, coupled to the first valve body and provided with a second chamber communicating with the first chamber;

a check valve, at least partially housed in the second chamber; and

at least a first fitting, mechanically coupled to the second valve body, the second valve body and the first fitting being distinct pieces,

wherein the first fitting is coupled to the second valve body by means of a coupling allowing the free rotation between the second valve body and the first fitting and preventing the uncoupling between the second valve body and the first fitting.

2. The valve assembly according to claim 1, wherein the first valve body and the second valve body are made in one piece.

6. The valve assembly according to claim 1, wherein the first fitting is coupled to the second valve body by means of an elastic ring.

7. The valve assembly according to claim 1, wherein the second chamber is defined by a wall having a substantially cylindrical inner cross section.

10. The valve assembly according to claim 1, wherein the check valve is a swing valve.

15. The valve assembly according to claim 10, wherein the second valve body is shaped so as to define an abutment ring for a swing of the check valve.

5. (canceled)

8. A valve assembly comprising:

a first valve body provided with a first chamber;

a shutter, which is movable in the first chamber and is connected to a control device;

a second valve body, coupled to the first valve body and provided with a second chamber communicating with the first chamber;

a check valve, at least partially housed in the second chamber; and

at least a first fitting, mechanically coupled to the second valve body, the second valve body and the first fitting being distinct pieces,

wherein the first fitting is shaped so as to define a substantially cylindrical passageway communicating with the second chamber;

a diameter of the passageway being equal to or smaller than a diameter of the second chamber.

3. The valve assembly according to claim 8, wherein the first fitting is coupled to the second valve body by means of a threaded coupling.

9. A valve assembly comprising:

a first valve body provided with a first chamber;

a shutter, which is movable in the first chamber and is connected to a control device;

a second valve body, coupled to the first valve body and provided with a second chamber communicating with the first chamber;

a check valve, at least partially housed in the second chamber; and

at least a first fitting, mechanically coupled to the second valve body, the second valve body and the first fitting being distinct pieces,

wherein the first fitting is shaped so as to define a substantially cylindrical passageway communicating with the second chamber;

a diameter of the passageway being smaller than a diameter of the second chamber.

4. The valve assembly according to claim 9, wherein the first fitting is coupled to the second valve body by means of a quick coupling.

11. A valve assembly comprising:

a first valve body provided with a first chamber;

a shutter, which is movable in the first chamber and is connected to a control device;

a second valve body, coupled to the first valve body and provided with a second chamber communicating with the first chamber;

a check valve, at least partially housed in the second chamber; and

at least a first fitting, mechanically coupled to the second valve body, the second valve body and the first fitting being distinct pieces,

wherein the first fitting is shaped so as to define a substantially cylindrical passageway communicating with the second chamber;

a diameter of the passageway being smaller than a diameter of the second chamber,

wherein the first valve body comprises an inlet connector and an outlet connector communicating with the first chamber;

the outlet connector being coupled to the second valve body.

12. The valve assembly according to claim 11, wherein the inlet connector and the outlet connector are aligned along a longitudinal axis (A).

14. The valve assembly according to claim 11, wherein the outlet connector defines an abutment ring for a swing of the check valve.

13. (canceled)

a shutter, which is movable in the first chamber and is connected to a control device;

a second valve body, coupled to the first valve body and provided with a second chamber communicating with the first chamber;

a check valve, at least partially housed in the second chamber; and

at least a first fitting, mechanically coupled to the second valve body, the second valve body and the first fitting being distinct pieces,

wherein the first valve body is mechanically coupled to a second fitting;

the first valve body and the second fitting being distinct pieces,

wherein the first valve body comprises an inlet connector and an outlet connector communicating with the first chamber;

the inlet connector being coupled to the second fitting.
