Rotary Slide Valve Coupling for Single-Servo Multi-Valve Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluidic valve units lack flexibility in setting multiple rotary slide valves, often requiring multiple motors for independent control, which increases complexity and cost.
Innovation Solution
A fluidic valve unit design where each pair of successive rotary slide valves is mechanically connected via a driver device, allowing one rotary slide valve to drive the next indirectly via a servo motor, enabling flexible and independent setting of multiple valves with a single servo motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple servo motors are used to independently control each rotary slide valve, then the setting flexibility and independence of each valve is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines multiple control functions into a single servo motor by mechanically coupling multiple rotary slide valves through common drive shafts and gears. This allows one motor to control multiple valves independently through the mechanical transmission system, reducing the total number of motors while maintaining control flexibility.
Solution Approach 2:
The single servo motor is designed to perform multiple control functions simultaneously by driving several rotary slide valves through the mechanical transmission system. The motor serves as a universal actuator that can position multiple valves independently through the gear and shaft mechanism.
2Adaptability or versatility
If multiple servo motors are used to independently control each rotary slide valve, then the independent control capability is improved, but the cost increases
Solution Approach 1:
The patent merges multiple actuation functions into a single servo motor unit by using mechanical transmission elements (drive shafts, gears, and coupling mechanisms). This consolidation reduces the total number of motors required, thereby lowering the overall system cost while preserving independent control capability through the mechanical linkage system.
Solution Approach 2:
The single servo motor is designed as a multi-functional actuator that can independently position multiple rotary slide valves through the mechanical transmission system. This universal motor design eliminates the need for multiple individual motors, reducing cost while maintaining independent control of each valve.
3Device complexity
If a single servo motor controls multiple rotary slide valves through mechanical connection, then the device complexity is reduced, but the control precision may deteriorate
Solution Approach 1:
The mechanical transmission system is segmented into independent control paths for each rotary slide valve, with each valve having its own drive shaft and gear mechanism. This segmentation allows the single servo motor to control multiple valves independently through the transmission system, maintaining control precision for each valve while reducing overall device complexity.
Solution Approach 2:
The patent introduces mechanical intermediaries (drive shafts, gears, and coupling mechanisms) between the single servo motor and the multiple rotary slide valves. These intermediaries transmit and distribute the motor's rotational motion to each valve independently, preserving control precision while allowing single-motor operation.

AI summary
A fluidic valve unit having a plurality of rotary slide valves arranged in series and a servo motor for setting the rotary slide valves, wherein each of the rotary slide valves comprises a rotary slide arranged in a rotary slide housing and drivable via a driveshaft by means of the servo motor. It is provided in this case that each two successive ones of the rotary slide valves are mechanically connected to one another via a driver device for the setting by means of the servo motor, wherein the driver device comprises a driver projection arranged on a first of the two rotary slide valves.
