Air Compressor Piston Body Pressure Relief Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressors require a mechanical safety valve to limit air pressure, increasing manufacturing costs due to the need for additional components.
Innovation Solution
A piston body design with a head that defines multiple air receiving spaces of varying shapes and depths, preventing pressure from exceeding safety levels without the use of a mechanical safety valve, utilizing an air-tight ring and resilient sheets to manage air intake and compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical safety valve is installed to limit air pressure, then the safety of the air compressor is improved, but the manufacturing cost increases
Solution Approach 1:
The patent extracts the safety valve component from the air compressor system by incorporating pressure-limiting functionality directly into the piston body structure. The piston body includes pressure relief openings that communicate with the compression chamber, allowing excess pressure to be vented through the piston structure itself rather than requiring a separate safety valve component.
Solution Approach 2:
The patent merges the safety function with the piston body structure by integrating pressure relief openings and venting passages directly into the piston body. This combines the compression function and safety function into a single integrated component, eliminating the need for a separate safety valve.

AI summary
A piston body for an air compressor includes a head which defines an air receiving space indented into the top surface of the head, wherein the air receiving space is bounded by a bottom surface and a surrounding surface and having a top opening at the top surface of the head. In operation, the air pressure of the compressed air produced from reciprocating motion of the piston body can keep less than a safety pressure set for an object to be inflated, without using a mechanical safety valve. Therefore, the operational safety can be increased, and the manufacturing cost can be reduced.
