Compressor Oil Filler Neck Geometry for Overfill Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressor systems face the risk of overfilling during oil top-up, which can disrupt operation or damage components due to the lack of effective mechanisms to prevent excess oil from being poured into the receiving volume.
Innovation Solution
A compressor oil receiving device with a housing and an oil filler neck that forms an air cushion to limit filling, featuring an outlet opening positioned to prevent overfilling, and includes adjustable and indicator mechanisms to ensure precise oil levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the receiving volume is made larger to accommodate more compressor oil, then the capacity to store oil is improved, but the risk of overfilling increases which can disrupt operation or damage components
Solution Approach 1:
The outlet opening of the oil filler neck is positioned at a predetermined height corresponding to the maximum oil level before filling begins. This preliminary positioning creates an air cushion that passively prevents overfilling, eliminating the need for active monitoring or control mechanisms during the filling process.
Solution Approach 2:
An air cushion is introduced as an intermediary between the incoming compressor oil and the receiving volume. This air cushion acts as a physical barrier that stops oil flow when the maximum level is reached, preventing direct contact between excess oil and critical components.
2Ease of operation
If the receiving volume is made larger to allow more filling flexibility, then the ease of operation is improved, but the measurement precision of oil level control deteriorates
Solution Approach 1:
The oil filler neck structure itself provides the measurement reference through its outlet opening position. The outlet opening automatically indicates the maximum fill level, eliminating the need for separate measurement devices or complex control systems. Users simply fill until oil reaches the outlet opening, making the system self-regulating.
3Reliability
If the outlet opening is positioned at the maximum oil level to prevent overfilling, then the reliability is improved, but the device complexity increases due to adjustable and indicator mechanisms
Solution Approach 1:
The invention extracts the overfill prevention function from complex active control systems and embeds it directly into the passive geometry of the oil filler neck. The outlet opening position alone provides the maximum level indication, eliminating the need for separate indicators, sensors, or adjustment mechanisms.
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
The device effectively prevents overfilling by creating an air cushion, allowing easy adjustment and monitoring of oil levels, ensuring safe and efficient operation of the compressor system.
Implementation Method 1
the outlet opening is arranged such that, by filling the receiving volume, an air volume enclosed by the housing on the one hand and the filled compressor oil on the other hand can be formed in the receiving volume

AI summary
The invention relates to a compressor-oil receiving device (10, 10') for a compressor system, for filling with a compressor oil (3) in order to transfer same into the compressor system, comprising: a housing (1, 1') which forms a receiving volume for the compressor oil (3); and an oil-filling pipe (2, 2') which has a filling opening (21, 21') on a side remote from the receiving volume and an outlet opening (22, 22') on a side next to the receiving volume; wherein the oil-filling pipe (2, 2') forms a housing opening for filling the receiving volume with the compressor oil (3), and wherein the outlet opening (22, 22') is located in such a way that, as a result of the receiving volume being filled, an air volume (7) which is enclosed by the housing (1, 1') and by the filled-in compressor oil (3) can be formed in the receiving volume.
