Abstract

An electromechanical valve is provided for the pneumatic actuation of a device of an internal combustion engine that includes, but is not limited to an external casing and one or more supporting dampers embedded in the external casing.

Claims (25)

1. An electromechanical valve for pneumatic actuation of a device of an internal combustion engine, comprising:

a movable valve member;

an external casing at least partially enclosing the movable valve member; and

a supporting damper embedded in the external casing, wherein the supporting damper comprises a perimetrical groove on a side surface, and wherein the supporting damper comprises a bore passing through a thickness of the supporting damper, and wherein the supporting damper comprises a frame that is configured to prevent a compression of the supporting damper, and wherein the frame comprises a stem axially inserted into the bore having opposite ends that are each provided with a respective flange that rests on the supporting damper, and wherein the stem comprises two sleeves coaxially inserted into each other, each of the two sleeves is integral with the flange, and

wherein a wall of the external casing comprises an opening with a perimetrical edge that fits the perimetrical groove and at least partially surrounds the supporting damper.

2. The electromechanical valve according to claim 1 , wherein the opening is an aperture with the perimetrical edge that completely surrounds the supporting damper.

3. The electromechanical valve according to claim 1 , wherein the supporting damper is at least partially formed of rubber.

4. The electromechanical valve according to claim 1 , wherein the supporting damper is cylindrical.

5. The electromechanical valve according to claim 1 , wherein the stem is tube-shaped.

6. The electromechanical valve according to claim 1 , wherein a first of the two sleeves includes a protruding collar and a second of the two sleeves includes an internal edge, and wherein the protruding collar and the internal edge comprise a prevent apparatus that is configured to prevent mutual unthreading once the two sleeves are in a predetermined mutual position.

7. A pneumatically actuated device for an internal combustion engine, comprising:

a movable member;

an external casing at least partially enclosing the movable member; and

a supporting damper embedded in the external casing, wherein the supporting damper comprises a perimetrical groove on a side surface, and wherein the supporting damper comprises a bore passing through a thickness of the supporting damper, and wherein the supporting damper comprises a frame that is configured to prevent a compression of the supporting damper, and wherein the frame comprises a stem axially inserted into the bore having opposite ends that are each provided with a respective flange that rests on the supporting damper, and wherein the stem comprises two sleeves coaxially inserted into each other, each of the two sleeves is integral with the flange, and

wherein a wall of the external casing comprises an opening with a perimetrical edge that fits the perimetrical groove and at least partially surrounds the supporting damper.

8. The pneumatically actuated device according to claim 7 ,

wherein the supporting damper comprises a perimetrical groove on a side surface, and

wherein a wall of the external casing comprises an opening with a perimetrical edge that fits the perimetrical groove and at least partially surrounds the supporting damper.

9. The pneumatically actuated device according to claim 8 , wherein the opening is an aperture with the perimetrical edge that completely surrounds the supporting damper.

10. The pneumatically actuated device according to claim 7 , wherein the supporting damper is at least partially formed of rubber.

11. The pneumatically actuated device according to claim 7 , wherein the supporting damper is cylindrical.

12. The pneumatically actuated device according to claim 7 , wherein the supporting damper comprises a bore passing through a thickness of the supporting damper.

13. The pneumatically actuated device according to claim 12 , wherein the supporting damper comprises a frame that is configured to prevent a compression of the supporting damper.

14. The pneumatically actuated device according to claim 13 , wherein the frame comprises a stem axially inserted into the bore having opposite ends that are each provided with a respective flange that rests on the supporting damper.

15. The pneumatically actuated device according to claim 14 , wherein the stem is tube-shaped.
