Compressor Surge Chamber Stabilizes Tire Pressure Readings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing compressor devices for flat tire repair kits experience pressure fluctuations due to the direct connection with the bottle unit, leading to a variance between the displayed manometer pressure and the actual tire internal pressure, causing uncertainty and potential damage.
Innovation Solution
Incorporating a surge chamber with a volume 1.0 to 3.0 times the stroke volume of the piston, equipped with an exhaust valve to stabilize the compressed air pressure and reduce fluctuations, thereby minimizing the difference between the manometer reading and the actual tire pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bottle unit is directly connected to the compressor device, then the hose for air intake is eliminated and stability is improved, but pressure fluctuation increases causing variance between manometer reading and actual tire pressure
Solution Approach 1:
A surge chamber is introduced as an intermediary component between the pump chamber and the discharge port. This surge chamber acts as a buffer that mediates the pressure fluctuations generated by the reciprocating piston, smoothing out the compressed air before it reaches the discharge port and providing more accurate pressure readings on the manometer.
2Stability of the object's composition
If the bottle unit is directly connected to the compressor device, then the center of gravity is lowered and stability is improved, but the passage volume decreases causing pressure fluctuation
Solution Approach 1:
The cylinder is segmented into two distinct chambers: a pump chamber for compression and a surge chamber for pressure stabilization. This segmentation allows the pump chamber to maintain its compact design for stability while the surge chamber provides the necessary volume to reduce pressure fluctuations, effectively separating the conflicting requirements.
3Reliability
If a unidirectional valve is provided to prevent sealing agent backflow, then compressor damage is prevented, but pressure fluctuation increases causing higher variance
Solution Approach 1:
The surge chamber is positioned upstream of the unidirectional valve, performing preliminary pressure stabilization before the air passes through the valve. This preliminary action reduces the pressure fluctuations that would otherwise be amplified by the valve's presence, maintaining both protection and measurement accuracy.

AI summary
In the present invention, a difference between a pressure displayed by a manometer of a compressor device and an actual internal pressure of a tire can be reduced. A compressor device (2) and a bottle unit (3) are directly connected. A cap (6) attached to the bottle unit (3) comprises a unidirectional valve (14) for preventing a reverse flow of a flat tire sealing agent to the side of the compressor device. A cylinder (12) of the compressor device (2) is provided with a pump chamber (11), and a surge chamber (18) which receives the compressed air from the pump chamber through an exhaust valve (16), wherein a volume (Q2) of the surge chamber (18) is 1.0 to 3.0 times of the stroke volume of a piston (10) in the pump chamber (11).
