Compressor Discharge Valve Presser Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing compressor designs in refrigerating cycle devices, such as air conditioners, face issues with noise and vibration due to the elastic deformation of the flange part's dug-down area, which affects the support rigidity of the rotating shaft and leads to bending vibrations.
Innovation Solution
The implementation of a discharge valve mechanism with a valve presser that includes a main body part and a fixed part extending in intersecting directions, which suppresses further deformation of the discharge valve and enhances the strength of the flange part at the dug-down area, thereby reducing noise and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flange part is dug down to install the discharge valve mechanism, then the discharge valve can be installed in the bearing, but the rigidity of the flange part is reduced causing elastic deformation and noise
Solution Approach 1:
The patent applies local quality by adding a reinforcing rib specifically at the dug-down part of the flange where the discharge valve mechanism is installed. This localized reinforcement maintains the overall simplicity of the bearing structure while specifically addressing the rigidity issue at the critical location where the discharge valve needs to be mounted.
Solution Approach 2:
The patent segments the flange part by adding a reinforcing rib that divides the dug-down area into distinct regions. This segmentation provides structural support to the weakened area created by the dug-down portion, preventing elastic deformation while maintaining the space needed for the discharge valve mechanism.
2Ease of operation
If the flange part is dug down to install the discharge valve mechanism, then the discharge valve can be installed, but the support rigidity of the rotating shaft is lowered causing bending vibration
Solution Approach 1:
The reinforcing rib is strategically placed at the dug-down part of the flange to provide localized support. This ensures that the rotating shaft maintains its support rigidity and stability while still allowing the discharge valve mechanism to be installed in the bearing structure.
3Ease of operation
If the flange part is dug down to install the discharge valve mechanism, then the discharge valve can be installed, but the boss part may incline toward the flange part causing noise
Solution Approach 1:
The reinforcing rib is positioned to provide local support to the boss part, preventing it from inclining toward the flange part during operation. This maintains the correct alignment and shape of the boss part while accommodating the discharge valve mechanism in the dug-down area.

AI summary
According to one embodiment, a compressor includes cylinders, a rotating shaft, bearings, and discharge valve mechanisms. Each of the discharge valve mechanisms includes a discharge valve and a valve presser. Regarding the valve pressers, each of the valve pressers includes a main body part lengthwise along the longitudinal direction of the discharge valve, and at least one of the valve pressers includes a fixed part extending in a direction intersecting the longitudinal direction of the discharge valve relatively to the main body part and fixed to the bearing.
