Abstract

The invention relates to an inlet structure of a reservoir pot, comprising a base plate, which can be arranged in an operating medium tank with the formation of a receiving volume below the base plate, and a plurality of first elements which extend from the base plate, wherein the first elements are at least partially spaced apart from one another, and operating medium can flow between the first elements into the receiving volume and can flow out of the receiving volume, wherein the first elements present a greater flow resistance in the outflow direction than in the inflow direction.

First claim

1 . to 14 . (canceled)

15 . An inlet structure of a reservoir pot, comprising:
a base plate which is arrangeable in an operating medium tank while forming a receptacle volume below or above the base plate; and a plurality of first elements which extend from the base plate, wherein the first elements are at least in part mutually spaced apart, and operating medium is able to flow into the receptacle volume and out from the receptacle volume between the first elements, the first elements in an outflow direction represent a higher flow resistance than in an inflow direction, and the first elements on an external side thereof that points counter to the inflow direction are configured so as to be convex, acute, or trapezoidal.

16 . The inlet structure according to claim 15 , wherein
the first elements are configured so as to taper in the outflow direction.

17 . The inlet structure according to claim 15 , wherein
the first elements have, in each case, one pocket which opens counter to the outflow direction.

18 . The inlet structure according to claim 15 , further comprising:
a plurality of second elements which extend from the base plate, wherein at least one second element is disposed between two neighboring first elements so as to reduce a flow cross section between the two neighboring first elements.

19 . The inlet structure according to claim 18 , wherein
only one second element is disposed between the two neighboring first elements.

20 . The inlet structure according to claim 18 , wherein
the flow cross section between the first elements and a respective neighboring second element is configured so as to taper in the inflow direction.

21 . The inlet structure according to claim 18 , wherein
the second elements are configured so as to taper in the inflow direction.

22 . The inlet structure according to claim 18 , wherein
the second elements are configured so as to be drop-shaped, and a tip of the drop shape is oriented in the inflow direction.

23 . The inlet structure according to claim 18 , wherein
the first elements and/or the second elements, when measured parallel to the base plate and at a largest point of the element, have a variable G, and the variable G is at most 0.2*D, where D is the diameter of the inlet structure.

24 . The inlet structure according to claim 18 , wherein
the first elements and/or the second elements, when measured parallel to the base plate and at a largest point of the element, have a variable G, and the variable G is at most 0 . 05 *D, where D is the diameter of the inlet structure.

25 . The inlet structure according to claim 18 , wherein
the first elements and/or the second elements are disposed exclusively in a distal region of the inlet structure.

26 . The inlet structure according to claim 18 , wherein
the first elements and/or the second elements are distributed across at least 50% of the face of the inlet structure.

27 . The inlet structure according to claim 18 , wherein
the first elements and/or the second elements are distributed across at least 70% of the face of the inlet structure.

28 . The inlet structure according to claim 18 , wherein the inlet structure comprises at least 10 first elements and/or wherein the inlet structure comprises at least 10 second elements.

29 . The inlet structure according to claim 18 , wherein
the inlet structure comprises at least 60 first elements and/or wherein the inlet structure comprises at least 60 second elements.

30 . A reservoir pot comprising an inlet structure according to claim 15 .

31 . A vehicle comprising:
an operating medium tank; and a reservoir pot according to claim 30 .
