Integrated Actuator Manifold for Compact Multi-Valve Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid systems with multiple valves require complex and bulky arrangements for actuation, leading to increased size, assembly complexity, and potential leak points due to numerous fluid connections and separate actuator housings.
Innovation Solution
A unitary actuator housing with integrated actuator cavities and internal fluid passages simplifies actuation by housing multiple actuating mechanisms within a single manifold, reducing the need for external fluid connections and providing compact, efficient control of valve operations through integrated porting and solenoid pilot valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple separate actuator housings are used for multiple valves, then each valve can be independently actuated, but the assembly size, complexity, and number of fluid connections increase
Solution Approach 1:
The patent combines multiple separate actuator housings into a single integrated actuator housing that contains multiple actuator cavities. Each cavity houses an actuating mechanism that can independently actuate a corresponding valve, while the unified housing structure reduces overall assembly complexity and eliminates the need for multiple separate housings and their associated external fluid connections.
Solution Approach 2:
The integrated actuator housing serves multiple functions simultaneously: it provides structural support for multiple actuators, contains internal fluid passages for actuating multiple valves, and acts as a unified mounting structure. This multi-functional design replaces what would otherwise require multiple separate components.
2Ease of operation
If multiple separate actuator housings are used for multiple valves, then each valve can be independently actuated, but the number of external fluid connections and potential leak points increases
Solution Approach 1:
By merging multiple actuator housings into one integrated structure with internal fluid passages, the patent reduces the number of external fluid connections required. The internal passages are sealed within the housing, minimizing exposed connection points and potential leak paths in the system.
3Device complexity
If a unitary actuator housing with integrated cavities is used, then assembly complexity and footprint are reduced, but the internal passage integration becomes more complex
Solution Approach 1:
The actuator housing is designed with distinct internal cavities that are segmented and dedicated to individual actuators. This segmentation allows for modular manufacturing approaches where cavities can be formed separately or as standardized features, simplifying the overall manufacturing process despite the integrated structure.
Solution Approach 2:
The patent utilizes three-dimensional internal passages that route fluid through the actuator housing in multiple directions and planes. This spatial arrangement allows efficient fluid distribution to multiple actuators within a compact volume, reducing the complexity of external piping while maintaining independent actuation capability.

AI summary
An actuator assembly includes a unitary actuator housing defining a plurality of actuator cavities each extending along a central axis from an upper surface of the actuator housing to a lower surface of the actuator housing. A plurality of actuating members are each disposed in an upper counterbore portion of a corresponding one of the plurality of actuator cavities and movable within the corresponding actuator cavity. A plurality of output shafts each extend through a lower bore in a corresponding one of the plurality of actuator cavities, with each output shaft being driven by a corresponding one of the plurality of actuating members.
