Air Compressor Resilient Sheet Valve for Piston Motion Smoothness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressors face issues with piston movement resistance and motor overheating due to a single exit hole design, where compressed air backforce restricts piston motion and increases motor stress, leading to decreased performance and risk of motor burnout.
Innovation Solution
An air compressor with a cylinder featuring multiple exit holes and air blocking walls, regulated by a resilient sheet with branches that can be individually opened and closed, preventing high-pressure air interference and allowing smoother piston motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single exit hole is used in the cylinder, then the valve mechanism is simple, but the piston body experiences greater resistance and cannot move smoothly
Solution Approach 1:
The single exit hole is segmented into multiple exit holes (first exit hole, second exit hole, etc.) distributed around the cylinder. Each exit hole is controlled by its own resilient sheet branch, dividing the flow control function into multiple independent channels. This segmentation reduces the resistance on the piston body by distributing the air flow paths while maintaining a relatively simple overall valve mechanism structure.
2Device complexity
If a single exit hole is used in the cylinder, then the device structure is simple, but the motor becomes too hot and risks burning out
Solution Approach 1:
The air discharge function is segmented into multiple exit holes, allowing compressed air to be discharged through multiple paths simultaneously. This increases the total discharge capacity, reduces back pressure, and improves motor cooling efficiency by enhancing air flow, thereby preventing motor overheating without significantly complicating the device structure.
Solution Approach 2:
The patent utilizes pneumatic principles by designing the resilient sheet with branches that respond to pressure differential to control exit holes. The compressed air itself is used to actuate the resilient sheet branches, creating a self-regulating system that optimizes discharge flow based on operating conditions, improving motor cooling through enhanced pneumatic flow management.
3Ease of operation
If compressed air backforce acts on the plug, then the valve mechanism can control air flow, but the piston body is subjected to greater resistance
Solution Approach 1:
The air flow control is segmented from a single plug-valve system into multiple resilient sheet branches, each controlling an individual exit hole. This segmentation distributes the backforce across multiple smaller areas and allows independent control of each flow path, reducing the total resistance on the piston body while maintaining effective air flow control capability.
Solution Approach 2:
The resilient sheet branches provide dynamic control of the exit holes, automatically adjusting their opening degree based on the pressure differential between the cylinder and air storage container. This dynamic response optimizes the balance between air flow control and piston resistance, allowing the system to adapt to varying operating conditions without manual intervention.

Function Achieved in This Case
The design enhances piston motion smoothness and compressor performance by isolating exit holes and managing high-pressure air flow, reducing resistance and motor stress, thus improving inflation speed and efficiency.
Implementation Method 1
When the compressed air produced in the cylinder pushes the branches of the resilient sheet up to open the exit holes
Implementation Method 2
the instantaneous high-pressure air that flows through the exit holes can be restrained by the air blocking walls to prevent the air from interfering with movements of the branches of the resilient sheet

AI summary
An improved air compressor includes a cylinder (2) fitted with a piston body (14), a main frame (11) for mounting a motor (12), and an air storage container (3). The cylinder (2) defines at its top wall (21) a plurality of exit holes (4, 5, 6), which are separated by a plurality of blocking walls (43, 53, 63) (44, 54, 64) and regulated by a resilient sheet (7) having a plurality of branches (72, 73, 74) corresponding to the exit holes. When the compressed air produced in the cylinder (2) pushes the resilient sheet (7) up to open the exit holes, the instantaneous high-pressure air that flows through the exit holes (4, 5, 6) can be restrained by the air blocking walls to prevent the air from interfering with movements of the branches of the resilient sheet, so that the piston body (14) can conduct reciprocating motion more smoothly and thus the performance of the air compressor can be increased.
