Abstract
A seal of non-hermetic design for installation between two components which can move relative to one another, includes a multiplicity of flexurally elastic sealing elements which each have an end connected fixedly to a seal-bearing device and a free, angled end with the point directed toward the surface of the one component, the seal-bearing device being connected fixedly to the other component and supporting the angled ends of the sealing elements at least on one side. The sealing elements are designed as thin-walled, angled spring leaves and are arranged parallel next to one another and in at least two layers one above the other with alternate overlapping.

A non-hermetic seal configured to be installed between a first component and a second component, the first component and the second component being relatively movable, comprising:
- a seal-bearing device, fixedly connectable to the first component;
- and
- a plurality of flexurally elastic sealing elements, each sealing element including a first end fixedly connected to the seal-bearing device and a free, angled second end having an edge, the second end angled relative to the first end with a bend portion arranged between the first end and the second end, the second end extending in a non-parallel direction toward a surface of the second component, the sealing elements being configured as thin-walled, angled spring leaves and being arranged in adjacent parallel arrangement and in at least two alternating, overlapping layers;
- wherein the seal-bearing device includes at least one sealing lip configured to support at least one side of the free, angled second ends of the sealing elements.
A non-hermetic seal configured to be installed between a first component and a second component, the first component and the second component being relatively movable, comprising:
- at least one seal-bearing device, fixedly connectable to the first component;
- and
- a plurality of flexurally elastic sealing elements, each sealing element including a first end fixedly connected to the seal-bearing device and a free, angled second end having an edge, the second end angled relative to the first end with a bend portion arranged between the first end and the second end, the second end extending in a substantially perpendicular direction toward a surface of the second component, the sealing elements configured as thin-walled, angled spring leaves and arranged in adjacent parallel arrangement and in at least two alternating, overlapping layers;
- wherein each seal-bearing device includes a sealing lip configured to support at least one side of the free, angled second ends of the sealing elements.
A device, comprising:
- a first component;
- a second component, the first component and the second component rotatable relative to each other;
- and
- a non-hermetic seal arranged between the first component and the second component, the seal including:
- at least one seal-bearing device, fixedly connectable to the first component;
- and
- a plurality of flexurally elastic sealing elements, each sealing element including a first end fixedly connected to the seal-bearing device and a free, angled second end having an edge, the second end angled relative to the first end with a bend portion arranged between the first end and the second end, the second end extending in a substantially perpendicular direction toward a surface of the second component, the sealing elements configured as thin-walled, angled spring leaves and arranged in adjacent parallel arrangement and in at least two alternating, overlapping layers;
- wherein each seal-bearing device includes a sealing lip configured to support at least one side of the free, angled second ends of the sealing elements.
