Air Compressor Piston Air Stop Sheet Pressure Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressors experience reduced service life due to incomplete discharge of compressed air and increased loading and electric current when restarted, resulting in back-pressure resistance that hampers piston movement.
Innovation Solution
The piston design incorporates a bending section with collapsible guide lines and an air stop sheet that opens at an angle θ, creating an air flowing space to balance cylinder pressure with the atmosphere, allowing smooth upward and downward movement by preventing back-pressure resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air stop sheet closes the conduit of the head of the piston when the air compressor stops, then the compressed air cannot be discharged out of the cylinder completely, but the piston hits the compressed airs in the cylinder to increase loading and electric currents, thus reducing service life
Solution Approach 1:
The air stop sheet is designed with a bending section that enables it to automatically open the air orifice before the piston returns, preliminarily releasing the compressed air. This preliminary action prevents the piston from hitting compressed air, thereby reducing loading and electric currents while extending service life.
Solution Approach 2:
The air stop sheet transitions from a static closed position to a dynamic open position through its bending section. This dynamic behavior allows the air orifice to be opened automatically when needed, enabling the piston to move smoothly without resistance from compressed air, thus improving reliability while reducing harmful forces.
2Reliability
If the air stop sheet closes the conduit completely, then airtightness is produced, but back-pressure resistance stops the piston to move smoothly
Solution Approach 1:
The air stop sheet is designed to be dynamic rather than static. The bending section allows it to automatically transition between closed and open states, providing airtightness when needed and eliminating back-pressure resistance when the piston needs to move smoothly, thus resolving the contradiction between airtightness and ease of operation.
Solution Approach 2:
The air stop sheet serves itself by automatically opening and closing based on the operational state of the air compressor. It maintains airtightness during compression and automatically opens to relieve back-pressure during piston movement, eliminating the need for external control mechanisms.

Function Achieved in This Case
This design ensures smooth piston movement and complete air discharge, extending the service life of the air compressor by eliminating back-pressure resistance and maintaining efficient operation.
Implementation Method 1
a back surface of the at least one acting zone of the respective one air stop sheet turns on relative to the plane of the top of the head at an open angle θ, thus producing an air flowing space; a pressure of a cylinder balances with atmosphere

AI summary
A piston of an air compressor (10) contains at least one fixing bolt (31), (32) configured to fix a plane (3) of a top of a head of the piston in at least one air stop sheet (30). A respective one of the at least one air stop sheet (30) includes at least one bending section (34) and at least one acting zone (36) opposite to the at least one bending section (34) and configured to cover at least one air orifice (35), and a back surface of the at least one acting zone (36) of the respective one air stop sheet (3) turns on relative to the plane (3) of the top of the head at an open angle θ, thus producing an air flowing space (Z). A pressure of a cylinder (13) balances with atmosphere, and the piston is not stopped by a back-pressure resistance to move smoothly in upward and downward moving strokes after the air stop sheet (30) moves again.
