Directional Control Fluid Valve Compact Housing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing directional control fluid valves are bulky and have a high number of components, making them complex and difficult to manufacture and maintain.
Innovation Solution
A directional control fluid valve design featuring a housing with a base part and a cover part, where ports are directly formed on one of the parts, eliminating the need for an intermediate part and reducing the number of components, with valve chambers and sealing mechanisms optimized for compactness and reduced force requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an intermediate plate with complex sealing is used to define throughflow paths, then the valve can establish fluid pathways, but the device becomes larger and has more components
Solution Approach 1:
The patent extracts and eliminates the intermediate plate component entirely. Instead of using an intermediate plate with complex sealing to define throughflow paths, the invention integrates the throughflow path definition directly into the valve body housing, thereby removing unnecessary components while maintaining functional reliability
Solution Approach 2:
The patent merges the functions of the intermediate plate and valve body into a single integrated structure. The housing itself now defines the throughflow paths that were previously required to be established by a separate intermediate plate, reducing component count and simplifying the overall device
2Adaptability or versatility
If ports are distributed across multiple housing parts, then the valve can accommodate multiple connections, but accessibility and manufacturing become more difficult
Solution Approach 1:
The housing is designed to serve multiple functions simultaneously: it provides structural support, defines throughflow paths, and accommodates all port connections on a single accessible surface. This multi-functional design eliminates the need to distribute ports across multiple housing parts, improving both manufacturability and assembly ease while maintaining full connection capability

AI summary
A directional control fluid valve for establishing a first throughflow path, with which fluid is sucked in and supplied under pressure to a consumer, and a second throughflow path with which fluid is sucked out of the consumer. The valve has a housing which has a tank port, a pressure port for connecting to a pressure side of a pump, a suction port for connecting to a suction side of the pump, and a consumer port. The valve has at least one valve flap which is arranged within the housing and which can be moved between a first flap position for establishing the first throughflow path and a second flap position for establishing the second throughflow path. The housing has two parts on which are formed in each case at least two valve seats. The housing has a base part on which the tank port, the pressure port, the suction port and the consumer port are formed, and a cover part which has closed ducts. The closed ducts are connected to the associated valve seats.
