Abstract

A valve device, in particular solenoid valve device, having at least one throughflow region ( 12 ), having at least one valve seat ( 14 ) and having an actuating unit ( 16 ) which has at least one valve body ( 18 ), at least an actuating element ( 20 ) provided for transmitting an actuation force to the valve body ( 18 ), and at least one first ventilation opening ( 24 ) arranged outside a fluid contact region ( 22 ) of the actuating element ( 20 ). The actuating unit ( 16 ) has at least one second ventilation opening ( 26, 28 ) arranged outside the fluid contact region ( 22 ) of the actuating element ( 20 ).

First claim

What is claimed is:

1. A valve device having at least one throughflow region ( 12 ), having at least one valve seat ( 14 ) and having an actuating unit ( 16 ) which has at least one valve body ( 18 ), at least an actuating element ( 20 ) for transmitting an actuation force to the valve body ( 18 ), and at least one first ventilation opening ( 24 ) arranged outside a fluid contact region ( 22 ) of the actuating element ( 20 ), wherein the fluid contact region of the actuating element is a section of the actuating element in contact with fluid flowing through the throughflow region, characterized in that the actuating unit ( 16 ) has at least one second ventilation opening ( 26 , 28 ) arranged outside the fluid contact region ( 22 ) of the actuating element ( 20 ), wherein the valve body ( 18 ) has the second ventilation opening ( 26 ), wherein the actuating element ( 20 ) is at least substantially of tubular form.

2. The valve device according to claim 1 , characterized in that the actuating unit ( 16 ) has at least one third ventilation opening ( 28 ) arranged outside the fluid contact region ( 22 ) of the actuating element ( 20 ).

3. The valve device according to claim 2 , characterized in that the actuating unit ( 16 ) has at least one duct ( 30 ) which connects at least two of the ventilation openings ( 24 , 26 , 28 ) to one another.

4. The valve device according to claim 1 , characterized in that the actuating element ( 20 ) is at least partially formed from plastic.

5. The valve device according to claim 1 , characterized in that the actuating element ( 20 ) is connected cohesively to the valve body ( 18 ).

6. The valve device according to claim 1 , characterized in that an opening direction ( 32 , 34 , 36 ) of at least one of the ventilation openings ( 24 , 26 , 28 ) is oriented at right angles to a longitudinal direction ( 37 ) of the actuating element ( 20 ).

7. The valve device according to claim 1 , wherein the valve device is a solenoid valve device.

8. A valve having at least one valve device ( 10 ) according to claim 1 .

9. A valve device according to claim 1 , characterized in that the actuating unit ( 16 ) has a duct ( 30 ) which extends through the actuating element ( 20 ) and which connects the first ventilation opening and the second ventilation opening.
