Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic pumps lack the ability to efficiently branch off a fluid partial flow from a main flow for diverse applications, limiting their range of use and adaptability to different pressure levels and fluid requirements.
Innovation Solution
A hydraulic pump design where individual vanes are guided in a drivable rotor to create opposing fluid spaces, allowing for the formation of separate chambers on the suction and pressure sides, enabling the branching off of a partial flow with adjustable volume and pressure, which can be used independently for various tasks and applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hydraulic pump is designed with a single main flow path, then the structure is simple and cost-effective, but the ability to branch off partial flow for diverse applications is limited
Solution Approach 1:
The pump is divided into functionally independent chambers: main chambers for the primary fluid flow and a separate sub-chamber for partial flow extraction. This segmentation allows each chamber to serve its specific purpose while maintaining overall system simplicity
Solution Approach 2:
A sub-chamber is extracted from the main pump structure to handle partial flow independently. This sub-chamber is connected to the pressure side and has its own outlet, allowing partial flow to be branched off for separate applications without interfering with the main flow path
2Adaptability or versatility
If the pump uses a standard single-flow design, then manufacturing is simple and cost-effective, but the range of application is limited
Solution Approach 1:
The chamber block is segmented into multiple independently manufacturable chambers (main chambers and sub-chamber) that can be designed and manufactured using standard processes, then assembled together to create a multi-functional pump suitable for various applications
3Adaptability or versatility
If the pump delivers a fixed volume flow, then the design is simple, but the ability to provide specifiable partial flow volume and pressure is limited
Solution Approach 1:
Different chambers are designed with different volumetric characteristics to deliver different pressure levels and flow volumes. The main chambers and sub-chamber have distinct designs optimized for their specific functions, allowing the pump to provide specifiable partial flow parameters

Function Achieved in This Case
Enables the creation of a specifiable fluid partial flow that can be used for emergency supplies, contamination analysis, and multiple technical applications, expanding the pump's range of use while allowing for modular integration with other components.
Implementation Method 1
hydraulic pumps that work according to the so-called displacement principle have sealed individual chambers in the pump housing, with fluid being transported in these chambers from the input side of the pump, formed by a suction connection, to the output side in the form of the pressure connection

AI summary
The invention relates to a device for branching a fluidic partial flow off a main flow by means of a hydraulic pump (10), said device comprising individual main chambers (12,14,16,18,20) which are sealed from each other and divided into functional groups, and operate according to the displacement principle. Said chambers enable fluid from at least one main flow inlet (22) to be transported from an inlet or suction side to an outlet or pressure side of the hydraulic pump (10) and then via at least one main flow outlet. At least one independent partial chamber (26) is provided for the transport of the partial flow, in addition to the main chambers (12,14,16,18,20), said partial chamber forming part of the pressure side of the hydraulic pump (10) and being connected to an independent partial current outlet (42) separate from the respective main flow inlet (22) and the respective main flow outlet (24).
