Abstract
An orthopedic device with a hydraulic damping device, a valve with a valve seat and a valve body that is subjected to a closing force. The closing force is applied via a valve spring that is pre-loaded towards the valve seat. A fluid connection between the hydraulic damping device and the valve seat is provided. The valve features an adjustment device for adjusting the preload of the valve spring.
Claims17
An orthopedic device comprising:
- a hydraulic damping device;
- a valve having a valve seat and a valve body, the valve body being subjected to a closing force along a direction of displacement, the closing force being applied via a valve spring that is pre-loaded towards the valve seat parallel to or along the direction of displacement;
- a valve spring holder that is coupled with the valve spring, wherein the valve spring holder is mounted in a housing and a first thread is configured on the valve spring holder, the first thread engaging with a second thread, which is arranged in the housing;
- a fluid connection between the hydraulic damping device and the valve seat;
- and
- an adjustment device for adjusting the pre-load of the valve spring, wherein the adjustment device is formed separately from and attached to the valve spring holder, and wherein the valve seat is adjustably positioned within the hydraulic damping device to adjust the pre-load of the valve spring, and wherein the valve seat is adjustable parallel to or along the direction of displacement.
