Abstract

The disclosure relates to a valve for controlling fluids, including a valve body defining a passage opening, a tapering valve seat formed on the valve body, a closing element configured to open up and to close off the passage opening at the tapering valve seat, and a protruding region adjoining the tapering valve seat. The protruding region extends over only part of a circumference of the tapering valve seat.

First claim

The invention claimed is:

1. A valve for controlling fluids, comprising:
a valve body defining a passage opening at an upper portion of the valve body;
a tapering valve seat formed on the upper portion of the valve body and encircling the passage opening;
a closing element configured to open and to close the passage opening by moving away from and contacting, respectively, the tapering valve seat; and
a protruding area at a first upper portion of the tapering valve seat, wherein:
the protruding area only extends over part of a circumference of the tapering valve seat;
the protruding area defines a length defined in a lifting direction of the closing element;
the length defined in the lifting direction is greater than a maximum lift of the closing element; and
the protruding area is only formed on less than one half of the circumference of the tapering valve seat and more than a third of the circumference of the tapering valve seat.

2. The valve as claimed in claim 1 , wherein the protruding area and the tapering valve seat are integrally formed with one another.

3. The valve as claimed in claim 1 , wherein:
the protruding area includes a castellated formation structure having a plurality of protruding elements that protrude above the tapering valve seat, and
the elements of the plurality of protruding elements are separated from one another by a plurality of spaces.

4. The valve as claimed in claim 3 , wherein:
each space of the plurality of spaces defines a first arc length in a circumferential direction,
each element of the plurality of elements defines a second arc length in the circumferential direction, and
the first arc length is the same as the second arc length.

5. The valve as claimed in claim 1 , wherein the tapering valve seat has a conical taper.

6. The valve as claimed in claim 1 , wherein the valve is configured as a non-return valve.

7. The valve as claimed in claim 1 , further comprising a non-protruding area at a second upper portion of the valve seat, the non-protruding area extending contiguously about the tapering valve seat for at least 180°.

8. The valve as claimed in claim 1 , wherein:
the tapering valve seat has a first circumference at an upper end and a second circumference at a lower end, and
the first circumference is greater than the second circumference.

9. The valve as claimed in claim 8 , wherein the closing element is configured to seal against the tapering valve seat at a position between the upper and lower ends of the tapering valve seat.

10. The valve as claimed in claim 1 , wherein the protruding area is configured to radially guide the closing element in an open position of the valve.

11. A brake device for vehicles, comprising:
a valve configured to control fluids including (i) a valve body defining a passage opening at an upper portion of the valve body, (ii) a tapering valve seat formed on the upper portion of the valve body and encircling the passage opening, (iii) a closing element configured to open and to close the passage opening by moving away from and contacting, respectively, the tapering valve seat, and (iv) a protruding area at a first upper portion of the tapering valve seat, wherein:
the protruding area only extends over part of a circumference of the tapering valve seat; and
the protruding area is configured to radially guide the closing element in an open position of the valve.

12. The brake device as claimed in claim 11 , the valve further comprising a non-protruding area at a second upper portion of the valve seat, the non-protruding area extending contiguously about the tapering valve seat for at least 180°.

13. A valve for controlling fluids, comprising:
a valve body defining a passage opening at an upper portion of the valve body;
a tapering valve seat formed on the upper portion of the valve body and encircling the passage opening;
a closing element configured to open and to close the passage opening by moving away from and contacting, respectively, the tapering valve seat; and
a protruding area at a first upper portion of the tapering valve seat, wherein:
the protruding area only extends over part of a circumference of the tapering valve seat; and
the protruding area is configured to radially guide the closing element in an open position of the valve.

14. The valve as claimed in claim 13 , further comprising a non-protruding area at a second upper portion of the valve seat, the non-protruding area extending contiguously about the tapering valve seat for at least 180°.

15. The valve as claimed in claim 13 , wherein:
the protruding area includes a castellated formation structure having a plurality of protruding elements that protrude above the tapering valve seat, and
the elements of the plurality of protruding elements are separated from one another by a plurality of spaces.

16. The valve as claimed in claim 15 , wherein:
each space of the plurality of spaces defines a first arc length in a circumferential direction,
each element of the plurality of elements defines a second arc length in the circumferential direction, and
the first arc length is the same as the second arc length.

17. The valve as claimed in claim 13 , wherein the protruding area is only formed on less than one half of the circumference of the tapering valve seat and more than a third of the circumference of the tapering valve seat.
