Solution Overview
Problem
Existing reciprocating compressors have complex suction silencers with many components, leading to increased production costs and assembly defects, which result in refrigerant leakage and assembly failures.
Innovation Solution
A simplified suction silencer design featuring a lower shell with an opened top and an upper shell fixed to form an inside space for noise reduction, with inlet and outlet passages and extension pipes that guide refrigerant perpendicular to each other, allowing for easy assembly and reduced component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the suction silencer has many components, then the noise reduction function is improved, but the device complexity increases and assembly defects increase
Solution Approach 1:
The patent combines multiple functional components (inlet passage, extension pipe, outlet passage) into an integrated suction silencer structure. The lower shell and upper shell are assembled to form a unified noise reduction chamber, eliminating the need for separate noise reduction components while maintaining effective noise attenuation through the integrated passage design.
Solution Approach 2:
The suction silencer structure serves multiple functions simultaneously: the inlet passage guides refrigerant entry, the extension pipe directs flow perpendicular to the inlet, the upper shell provides noise reduction, and the outlet passage discharges refrigerant. This multi-functional design eliminates the need for separate components for each function, reducing overall complexity while maintaining performance.
2Object-affected harmful factors
If the suction silencer has many components, then the noise reduction function is improved, but the production cost increases
Solution Approach 1:
By merging the inlet passage, extension pipe, outlet passage, and noise reduction chamber into a single integrated suction silencer assembly, the patent reduces the total number of parts that need to be manufactured, stored, and assembled. This integration directly lowers production costs while maintaining effective noise reduction through the unified structure.
Solution Approach 2:
The suction silencer is divided into two main segments (lower shell and upper shell) that can be manufactured separately and then assembled together. This segmentation allows for simplified manufacturing of each component while maintaining the integrated functional benefits, balancing production cost reduction with assembly complexity management.
3Object-affected harmful factors
If the suction silencer has many components, then the noise reduction function is improved, but the assembly productivity decreases
Solution Approach 1:
The integration of multiple functions into a single suction silencer assembly reduces the number of separate components that require assembly. The lower shell and upper shell are assembled together to form the complete noise reduction structure, eliminating multiple assembly steps and significantly improving assembly productivity while maintaining effective noise attenuation.
4Object-affected harmful factors
If the suction silencer has many components, then the noise reduction function is improved, but the assembly tolerance requirements increase causing refrigerant leakage
Solution Approach 1:
By combining multiple components into an integrated suction silencer assembly with fewer connection points, the patent reduces the cumulative effect of assembly tolerances. The lower shell and upper shell are designed to assemble into a unified structure with reduced leakage paths, improving reliability while maintaining noise reduction functionality.

Implementation Method 1
an upper shell fixed to the top of the lower shell to form an inside space for reducing noise of drawn refrigerant
Implementation Method 2
The flow direction of the refrigerant introduced into the inside space is perpendicular to a flow direction of the refrigerant discharged from the inside space
Data Source
AI summary
A suction silencer in a compressor is disclosed, including a lower shell having an opened top, that draws refrigerant, and an upper shell fixed to the top of the lower shell to form an inside space that reduces noise of drawn refrigerant, and that discharges refrigerant in a direction different from a flow direction of the refrigerant introduced into the lower shell, thereby simplifying a structure to permit easy assembly.
