Embodiment Construction

[0025] figure 1 A cross-sectional view of a prosthetic knee joint according to a first embodiment of the present invention is shown. The prosthetic knee joint has an upper part 2 with an upper fastening element 4 on which, for example, a prosthetic sleeve or another prosthetic component can be arranged. The upper part 2 is arranged pivotably on the lower part 6, which has a first component 8 and a second component 10, on which a lower fastening element 12 is located, which in the exemplary embodiment shown Medium constructed as a tube clamp for calf tubes. The first component 8 is arranged on the second component 10 so as to be pivotable about a control shaft 14 .

[0026] Located in the prosthetic knee joint is a hydraulic assembly which has an extension chamber 16 , a flexion chamber 18 and a valve 20 which is arranged in a fluid connection 22 via which the extension chamber 16 is connected to the flexion chamber 18 . The extension chamber 16 is separated from the flexion...

Abstract

The invention relates to a valve (20) with an inlet (28), an outlet (30), which is connected to the inlet (28) by a fluid connection, and a valve body (26) which, by displacement along a displacementdirection, can be brought to a first position, in which the fluid connection is blocked, and to a second position, in which the fluid connection is opened, wherein the inlet (28) is configured and arranged in such a way that a fluid entering through the inlet (28) applies a total force to the valve body (26), which total force at least also acts in a force direction perpendicular to the displacement direction when the valve body (26) is located in the first position.

Description

Technical field [0001] The invention relates to a valve having: an inlet; an outlet connected to the inlet by a fluid connection; and a valve body capable of being placed in a first position and in a second position by being moved along a direction of movement. position, the fluid connection is blocked in the first position and the fluid connection is opened in the second position. The invention also relates to a prosthetic knee joint having the valve. Background technique [0002] Prosthetic knee joints and hydraulic valves that can be used for this have long been known from the prior art. The prosthetic knee joint should be damped to varying degrees during different phases of the walking cycle. Small damping is required during the swing phase, while greater damping is desired during the stopping phase. At the beginning of the stop phase, at heel strike, the knee prosthesis is usually fully extended. It is important in this case that a high resistance resists possible f...
