Abstract:
The disclosure relates to a switching element comprising an external part and an internal part, which is axially displaceable in a bore of the external part. At least one radially displaceable locking element is disposed within at least one receptacle of the internal part and includes a flattened portion on a radially outwardly directed end. At least one recess of the external part can be acted upon by a control pressure and the at least one locking element can thereby be radially displaced from the locking position into a release position. At least in a respective locking position, a chamber delimited by the at least one locking element is spatially separated from the at least one recess of the external part by a respective locking section. At least one bypass is designed, which indirectly fluidly connects the at least one recess of the external part and a respective chamber.
