Pivotable Hydraulic Filter Cartridge for Flexible Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic machine filter systems with fixed connector positions restrict the orientation of the filter cartridge, limiting flexibility and potentially causing issues with fluid flow due to fixed orientations.
Innovation Solution
A filter apparatus with a pivoting retaining part and pressure chambers allows continuous adjustable orientation of the filter cartridge relative to a pivot axis, maintaining a compact design and ensuring fluid flow independence from pivot positions, incorporating a cold start valve for efficient pressurized fluid management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the connector positions are fixed on the sealing face, then the interface to the hydraulic machine remains simple and compact, but the orientation of the filter cartridge is restricted to a single fixed position
Solution Approach 1:
The connecting part is segmented into a fixed base portion (with sealing face and connectors) and a movable pivoting appendage (with retaining part). This segmentation allows the filter cartridge orientation to be adjusted independently while keeping the interface to the hydraulic machine simple and fixed.
Solution Approach 2:
The retaining part is made dynamically adjustable through the pivoting appendage, which can rotate about a pivot axis. This dynamic capability allows the filter cartridge to be oriented in different directions while maintaining a compact fixed interface with the hydraulic machine.
2Ease of operation
If the filter cartridge orientation is fixed, then the device structure is simple and compact, but fluid flow may be affected by fixed orientation limitations
Solution Approach 1:
The pivoting appendage enables dynamic adjustment of the filter cartridge orientation, allowing optimal positioning for fluid flow while maintaining a compact fixed structure at the hydraulic machine interface.
3Reliability
If a cold start valve is added to the filter apparatus, then pressurized fluid management is improved, but the device complexity and space requirements increase
Solution Approach 1:
The cold start valve is merged into the pivoting appendage structure, combining multiple functions (filter cartridge retention, pivoting capability, and cold start valve housing) into a single integrated component. This reduces overall device complexity and space requirements compared to having separate components for each function.

AI summary
A filter apparatus is for use with a hydraulic machine. The filter apparatus includes a connecting part and a filter cartridge. The connecting part includes a sealing face, which is configured for sealing abutment on the hydraulic machine. An input connector and an output connector are arranged within the sealing face. The filter apparatus further includes a separate retaining part on which the filter cartridge is fixedly received. The connecting part has a pivoting appendage extending along a pivot axis on a side of the connecting part facing away from the sealing face. The retaining part is fluid-tightly adapted to the pivoting appendage such that (i) its pivoting position with respect to the pivot axis is continuously adjustable relative to the connecting part, and (ii) between the retaining part and the pivoting appendage, a first and a second pressure chamber are arranged.
