AI Technical Summary

Benefits of technology

The patent text describes a device used to lock and shape a valve assembly. The rotating part / rotor is used for both locking and shape recovery. The device includes a spring and a jolt that work together to achieve the desired shape recovery. The text also mentions the use of an infilling process to eliminate or minimize dangerous cavities in the valve assembly. This process ensures that the flow cross section between the fluid inlet and outlet is not more than ten square millimeters.

Problems solved by technology

But a satisfactory solution has not yet been achieved with known valves.

This leads to inaccuracies in the adjustment.

In addition, a slight unintended rotational movement of the abutment can already lead to considerable valve modifications.

As a person is unable nowadays to evade exposure to such things, proposed solutions of this kind are generally impractical.

The clicking noises result for example by the use of spring steel or another elastic material, which on pressing suddenly bulges, thereby creating a noise.

This material is biocompatible.

In addition, the shape of the springs / leaf springs also influences how the noise-generating deformation is produced.

Similarly, the shape recovery in one possible embodiment ends with the generation of noise.

Moreover, a wave-shaped bulge structure can have a damping effect on the noise generation.

The additional bearing that can slide longitudinally appears at first sight to be more costly than the integrally formed design with a valve cover.
