Pivoting Vane Pump Wheel for Directional Pressure Control

The vane elements are made dynamically adjustable through a pivoting device that allows them to rotate between an action position (where they generate delivery pressure) and a rest position (where they minimize pressure). This dynamic adjustment enables the pump to adapt its performance characteristics based on the direction of rotation, achieving maximum efficiency in the desired operating direction while minimizing energy loss in the opposite direction.

The pivoting device enables the vane elements to dynamically change their orientation relative to the fluid flow. In the action position, the vanes are angled to generate delivery pressure. In the rest position, they are oriented to minimize frictional forces. This dynamic reconfiguration eliminates the harmful frictional forces that would otherwise occur when the pump operates in the opposite direction of rotation.

The pivoting device introduces a simple rotational mechanism that allows the vane elements to change their angle relative to the base body. This dynamic element adds minimal structural complexity while providing significant adaptability: the vanes can be positioned to generate maximum delivery pressure in one direction and minimal pressure in the opposite direction, enabling directional control of pump performance.

The pivoting device is designed as a simple rotational mechanism that allows the vane elements to change their angular orientation. This dynamic adjustment capability achieves maximum delivery pressure in the desired direction while the structural complexity of the pivoting device itself is minimized through straightforward mechanical design elements such as pivots, slots, or articulated connections.
