Integrated Compressor Oil Channels to Reduce Leak-Prone Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressor assemblies face challenges in designing a compact, cost-effective, and reliable oil circulation system, especially for oil-free or oil-less compressor elements, due to the complexity of reducing oil line connections and minimizing the risk of oil leaks.
Innovation Solution
The compressor assembly integrates the oil circulation system within the compressor assembly housing, using pass-through channels to form oil lines and reducing external connections, while also optimizing the oil filtering system to adapt to the needs of the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the oil circulation system uses multiple external oil lines to connect components, then the system can provide adequate lubrication and cooling, but the number of connections increases and the risk of oil leaks increases
Solution Approach 1:
The patent integrates multiple oil circulation functions into a single unified oil reservoir that serves as both the oil supply source and the oil return collection point. The motor housing and compressor housing are merged into a single integrated housing structure that contains all oil circulation components, eliminating the need for multiple external oil lines and connections between separate components.
Solution Approach 2:
The oil reservoir is designed to perform multiple functions: it serves as the oil supply source, the oil return collection point, and the housing for both the motor and compressor elements. This multi-functional design reduces the number of separate components and their interconnections, thereby reducing leak risks while maintaining adequate lubrication and cooling.
2Volume of moving object
If the compressor assembly uses separate motor housing and compressor housing with multiple connections, then components can be independently manufactured, but the overall assembly size increases and compactness decreases
Solution Approach 1:
The patent merges the motor housing and compressor housing into a single integrated housing structure that contains all oil circulation components. This consolidation reduces the overall assembly size and improves compactness while maintaining the ability to manufacture the housing as a single piece or pre-assembled unit.
3Reliability
If the oil circulation system is designed with separate oil supply and oil return lines, then oil flow control is improved, but the number of oil lines and connections increases
Solution Approach 1:
The patent combines the oil supply and oil return functions into a single oil reservoir that serves both purposes. Oil is supplied from the reservoir to the motor and compressor components, and the same reservoir collects the returned oil, eliminating the need for separate supply and return lines and reducing the total number of oil lines in the system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces the number of oil line connections, minimizes the risk of oil leaks, and enhances the reliability and compactness of the compressor assembly, while allowing for easier assembly and reduced production costs.
Implementation Method 1
oil is circulated through oil lines of the oil circulation system from the oil reservoir to the concerned components to be lubricated or cooled and back to the oil reservoir
Implementation Method 2
the oil circulation system also comprises an oil cooler for cooling oil circulating through the oil circulation system
Implementation Method 3
the oil circulation system also comprises an oil filter for filtering oil flowing through one or more lines of the oil circulation system
Implementation Method 4
the motor has a motor housing comprising a central motor housing body executed as a jacket in which channels are provided which are connected to oil lines of the oil circulation system for circulating oil through the motor jacket

AI summary
A compressor assembly includes a compressor assembly housing, a motor that drives one or more compressor rotors, an oil reservoir, an oil cooler, and an oil filter. The motor has a motor jacket with first group channels for cooling the motor, and the compressor assembly housing having one or more pass-through channels forms at least a part of an oil line that interconnects components of the compressor assembly.
