AI Technical Summary

Technical Problem

Existing solenoid valve assemblies require significant structural space, are expensive to manufacture, and are complex to assemble in vehicle applications, making it difficult to achieve a compact and space-saving structure.

Method used

The first and second winding units of the stator assembly are stacked along a common central longitudinal axis. Combined with modular magnetic circuit design and tube wall construction, the drive unit achieves a compact structure through end-side electrical connectors and uses the stepping rotation of the rotor assembly for angle control.

Benefits of technology

This design achieves a compact and space-saving structure for air spring valves, reducing manufacturing costs, simplifying the assembly process, and improving assembly accuracy and power performance.

Abstract

This invention relates to an actuation device for valves, particularly for air spring valves. The actuation device includes a stator assembly having a first winding unit with a first electrical contact and a second winding unit with a second electrical contact. Additionally, the first and second winding units are stacked along a common central longitudinal axis and configured to rotate a rotor assembly, which can be positioned within the internal space of the stator assembly, about the central longitudinal axis. The first and second electrical contacts are disposed at their ends on the first winding unit.
