Compressor Oil Separator Structure for Gas Release and Oil Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compressors with oil separators face challenges in efficiently discharging gas from the oil storing chamber, leading to reduced oil levels and compromised production workability due to complex gas release passageway requirements.
Innovation Solution
The compressor design incorporates a separation chamber adjacent to the discharge chamber with a gas release passageway formed between two compressor forming members, allowing efficient discharge of gas from the oil storing chamber and improving production workability by eliminating the need for complex groove formations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gas release passageway is provided between parts of the oil storing chamber to discharge gas, then gas can be discharged from the oil storing chamber, but the workability in production deteriorates due to the need to form a groove with a complicated shape
Solution Approach 1:
The oil storing chamber is divided into multiple parts (first part with lower hole, second part without lower hole), and the gas release passageway is formed between these parts. This segmentation allows gas to be discharged efficiently while simplifying the manufacturing process by avoiding the need to form complicated grooves in a single piece.
Solution Approach 2:
The gas release function is extracted from the oil storing chamber structure and implemented as a separate passageway between parts. This allows the main chamber structure to remain simple for manufacturing while adding the gas release function through the inter-part passageway.
2Reliability
If the oil separation section is formed by machining in the casing, then the oil separation function is achieved, but the number of parts increases and assembly becomes more complex due to requirements for seal bolts and snap rings
Solution Approach 1:
The oil storing chamber is integrated into the compressor casing as a unified structure rather than a separate component. The gas release passageway is formed as part of the chamber structure between parts, eliminating the need for separate seal bolts and snap rings, thus reducing the number of parts while maintaining the oil separation function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design ensures sufficient oil storage by efficiently discharging gas from the oil storing chamber and enhances production workability by simplifying the gas release passageway formation process.
Implementation Method 1
separates oil-containing gas, being introduced, into gas and oil by centrifugal separation
Implementation Method 2
a portion of the oil storing chamber, other than a portion where the lower hole is opened, is communicated with the separation chamber via a gas release passageway

AI summary
A compressor incorporated with an oil separator having a separation chamber, which is placed adjacent to a discharge chamber, has a space formed in the entire inside of the separation chamber, separates oil-containing gas, being introduced, into gas and oil by centrifugal separation, allows the separated oil to drop downward, and upwardly extracts the separated gas, and also having a lower hole for introducing the separated oil into an oil storing chamber. The oil separator is formed as a joining structure of two compressor forming members, and a portion of the oil storing chamber, other than a portion where the lower hole is opened, is communicated with the separation chamber via a gas release passageway at least a part of which is formed between the two compressor forming members. Gas is efficiently discharged from the portion of the oil storing chamber where the lower hole of the oil separator is not opened, a sufficient amount of stored oil is secured in the oil storing chamber, and in addition, workability in production of the device is improved.
