Air Compressor Buffering Compartment Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressors lack a buffering compartment in the cylinder housing, which limits the effective operation of the piston and results in over-pressurization of air, as there is no space to partially receive pressurized air, hindering efficient compression and pumping.
Innovation Solution
An air compressor assembly with a cylinder housing featuring a compressing chamber and a buffering compartment that communicates with the chamber to receive a portion of the pressurized air, including a partition with an air passage, a spring-biased check valve, and an adjustable plug to manage air pressure and prevent over-pressurization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a solid structure is used in the compressing chamber, then the piston can be effectively moved, but the air cannot be effectively compressed and over-pressurization occurs
Solution Approach 1:
The compressing chamber is segmented into two functional regions: a solid-structured compression zone for effective piston movement and a buffering compartment with cavity space for receiving pressurized air. This segmentation allows the piston to effectively compress air in one region while the other region absorbs the pressurized air, preventing over-pressurization and improving overall compression efficiency.
2Device complexity
If no buffering compartment is provided, then the structure is simpler, but the piston cannot effectively compress air and over-pressurization occurs
Solution Approach 1:
The buffering compartment is merged with the compressing chamber as an integrated feature of the cylinder housing, rather than being a separate external component. This merging allows the housing to simultaneously provide structural support, enable piston movement, and buffer pressurized air, improving compression efficiency without proportionally increasing device complexity.
3Volume of moving object
If the compressing chamber has no cavity space, then the structure is more compact, but the piston cannot effectively pump air
Solution Approach 1:
The buffering compartment utilizes the radial dimension by extending inward from the outer peripheral surface of the compressing chamber toward the piston. This dimensional approach allows the system to maintain a compact overall volume while incorporating additional buffering space within the radial profile, enabling effective air pumping without excessive volume increase.

Function Achieved in This Case
The solution allows for effective air compression and pumping by buffering pressurized air, enhancing the compressing or pumping effect and preventing over-pressurization, thereby improving the operational efficiency of the air compressor.
Implementation Method 1
a spring-biased check valve disposed in the outlet receptacle and engaged with the valve seat and the partition for selectively blocking the air passage of the partition and for guiding the pressurized air to flow from the chamber of the cylinder housing into the bore of the outlet receptacle, and to prevent the pressurized air from flowing backwardly from the bore of the outlet receptacle into the chamber of the cylinder housing
Implementation Method 2
a piston slidably received in the chamber of the cylinder housing, a motor coupled to the piston for moving the piston relative to the cylinder housing in a reciprocating action in order to generate a pressurized air
