Device for exposing an opening in a housing part of a steering gear
A device for exposing at least one opening in a housing part of a steering gear in a vehicle steering system is provided with a closure element, which closes the opening, and an operating element. At least one of the properties of the operating element changes when coming in contact with a liquid so that the opening can be exposed by the closure element after cooperation of the operating element with the closure element. The closure element is at least partially covered by a cover part and is designed as a buoyant body, or is provided with one or more buoyant bodies, wherein the cover part completely exposes the opening when liquid makes contact with the cover part.
