Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cylinder covers for alternative compressors suffer from physical deformations due to pressure exerted by exhaustion valve stoppers, leading to compromised sealing integrity and fluid leakage.
Innovation Solution
A cylinder cover design featuring support projections spaced from the sealing contour through gaps, allowing for elastic deformation that absorbs pressure without transferring stress to the sealing regions, maintaining the integrity of the compressor's sealing interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If support extensions are projected directly from the joint contour to support exhaustion valve stoppers, then the structural support capability is improved, but physical deformations occur leading to compromised sealing integrity
Solution Approach 1:
The support projection is segmented from the sealing contour through the introduction of gaps. This segmentation allows the support function to be separated from the sealing function, enabling independent optimization of both. The support projection can deform elastically under pressure without transmitting stress to the sealing contour, while the sealing contour maintains its integrity.
Solution Approach 2:
Different regions of the cylinder cover are given different mechanical properties. The support projection region is designed to be elastic and deformable to absorb pressure, while the sealing contour region is designed to be rigid and stable to maintain sealing. This local differentiation of mechanical properties resolves the contradiction between support strength and sealing reliability.
2Reliability
If the support projection is spaced from the sealing contour through gaps, then sealing integrity is maintained, but structural support capability may be reduced
Solution Approach 1:
The support projection is designed with dynamic characteristics, allowing it to deform elastically under pressure from the exhaustion valve stopper. This dynamic response enables the support projection to absorb pressure fluctuations and maintain effective support while preventing stress transmission to the sealing contour. The gaps provide the necessary compliance for this dynamic behavior.
Solution Approach 2:
The gaps act as intermediaries between the support projection and the sealing contour. They serve as stress-isolating elements that decouple the mechanical loads, allowing the support projection to perform its supporting function while preventing the transmission of deforming stresses to the sealing contour, thus maintaining both support capability and sealing integrity.
