Compressor Vibration Eliminator Integrated Ferrule Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In compressors used in cooler appliances, there is a risk of refrigerant leakage at the coupling point between the vibration eliminator and the cylinder head, and the assembly process is complex, leading to potential leaks and inefficiencies.
Innovation Solution
The compressor design includes a housing with a body and a cylinder bearing, featuring an annular cut-out on the face surface for the cylinder bearing, with a discharge tube ferrule that has two ports for the vibration eliminator, and concentric gas outlet ducts to prevent leakage, along with a grooved structure in the discharge tube ferrule to reduce back pressure, allowing for secure and efficient fluid transmission without additional coupling members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional coupling methods (ferrule welded to discharge tube fastened to cylinder head or ferrule coupled to slot) are used, then the vibration eliminator can be connected to the compressor, but refrigerant leakage occurs at the coupling point
Solution Approach 1:
The patent merges the discharge tube ferrule and vibration eliminator into a single integrated component. The vibration eliminator is directly formed with an integrated discharge tube ferrule structure, eliminating the need for separate coupling operations between the ferrule and cylinder head. This integration ensures reliable refrigerant sealing while simplifying the assembly process to a single insertion operation through the cut-out in the cylinder head.
Solution Approach 2:
The integrated discharge tube ferrule acts as an intermediary component that provides a sealed connection between the compression chamber and the vibration eliminator. The ferrule structure includes a discharge tube insertion hole that receives the discharge tube and forms a sealed pathway for refrigerant flow, eliminating leakage risks at multiple coupling points while maintaining structural integrity.
2Reliability
If additional coupling members (gaskets and bolts) are used to prevent leakage, then sealing is improved, but assembly complexity and number of parts increase
Solution Approach 1:
The integrated vibration eliminator with built-in discharge tube ferrule is self-sealing through its inherent structure. The design eliminates the need for separate gaskets and coupling bolts by incorporating the sealing function directly into the integrated component structure, allowing simple insertion through the cut-out in the cylinder head while maintaining reliable refrigerant sealing.
3Device complexity
If the discharge tube ferrule is integrated with the vibration eliminator, then assembly is simplified and leakage is prevented, but the structural design becomes more complex
Solution Approach 1:
The patent combines the vibration eliminator and discharge tube ferrule into a single molded component. This integration simplifies assembly to a single insertion operation while the manufacturing complexity is managed through injection molding or similar processes that can efficiently produce the integrated structure with internal channels and sealing features.
