A device for stabilizing body joints, comprising: a receptacle, wherein the receptacle is filled with a filling medium, wherein the filling medium is a fluid, a first body for interacting with the filling medium, wherein the first body is slidably arranged in the receptacle, a force transmission means for transmitting an external force to the first body, a second body for interacting with the filling medium, which is slidably arranged in the receptacle, wherein a surface of the first body, relative to which the filling medium performs a relative flow movement when the first body is moved due to an external force, forms a first shear surface and a surface of the second body, relative to which the filling medium performs a relative flow movement when the first body is moved due to an external force, forms a second shear surface, wherein the second body is elastically coupled to the first body via a coupling element, the coupling element comprising a spring element, wherein the second body and/or the first body having at least one passage opening, through which the filling medium can flow, and wherein the first body forms a valve body and the second body forms a valve seat, so that a flow of the filling medium through the passage opening can be permitted or prevented depending on the valve position, characterized in in that, depending on the size of a gap size between the second body and the receptacle and/or a spring force of the coupling element and/or the second shear surface, a threshold value is defined which determines a speed of the second body at which, due to the flow of the filling medium along the second shear surface, leads to an increase in shear stress which does not permit any further movement of the second body. a receptacle, wherein the receptacle is filled with a filling medium, wherein the filling medium is a fluid, a first body for interacting with the filling medium, wherein the first body is slidably arranged in the receptacle, a force transmission means for transmitting an external force to the first body, a second body for interacting with the filling medium, which is slidably arranged in the receptacle, wherein a surface of the first body, relative to which the filling medium performs a relative flow movement when the first body is moved due to an external force, forms a first shear surface and a surface of the second body, relative to which the filling medium performs a relative flow movement when the first body is moved due to an external force, forms a second shear surface, wherein the second body is elastically coupled to the first body via a coupling element, the coupling element comprising a spring element, wherein the second body and/or the first body having at least one passage opening, through which the filling medium can flow, and wherein the first body forms a valve body and the second body forms a valve seat, so that a flow of the filling medium through the passage opening can be permitted or prevented depending on the valve position, characterized in in that, depending on the size of a gap size between the second body and the receptacle and/or a spring force of the coupling element and/or the second shear surface, a threshold value is defined which determines a speed of the second body at which, due to the flow of the filling medium along the second shear surface, leads to an increase in shear stress which does not permit any further movement of the second body.
