Compressor Oil Filler Neck Layout for Overfill Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Overfilling of the compressor oil receiving volume can disrupt operation or damage components in compressor systems, particularly in oil-lubricated compressors, due to the introduction of excess oil beyond the intended maximum level.
Innovation Solution
A compressor-oil-receiving apparatus with a housing and an oil filler neck having a filling opening directed away from the receiving volume and an outlet opening directed toward it, forming an air cushion that limits filling, with the outlet opening positioned to define the maximum oil level, and optionally featuring a movable or rotatable neck and position indicators to control the filling process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiving volume is filled with compressor oil beyond the maximum oil level, then the compressor system has sufficient lubrication, but overfilling occurs which can disrupt operation or damage components
Solution Approach 1:
The patent applies preliminary action by pre-defining the maximum oil level through the outlet opening position of the oil filler neck before filling occurs. The outlet opening is positioned at the desired maximum level, creating a predetermined stop that prevents overfilling before it can happen. This proactive design eliminates the need for active monitoring or control during the filling process.
Solution Approach 2:
The system applies self-service by using the filling process itself to automatically stop at the correct level. As oil fills the receiving volume, it naturally rises to the outlet opening where it begins to escape, creating a self-regulating mechanism that fills the oil to the exact maximum level without external intervention or additional control systems.
2Quantity of substance
If the receiving volume is filled with compressor oil, then the compressor system receives necessary lubrication, but the risk of overfilling increases without proper filling control
Solution Approach 1:
The oil filler neck acts as an intermediary element between the filling source and the receiving volume. It mediates the filling process by providing a controlled pathway with a predefined outlet opening position that automatically limits the oil quantity. This intermediary structure translates the filling action into a self-controlled process that delivers the correct oil amount.
Solution Approach 2:
The patent applies parameter changes by utilizing the physical parameter of oil level height to control the filling process. The outlet opening is positioned at a specific height corresponding to the maximum oil level, and as the oil level reaches this parameter threshold, the filling automatically stops. This converts a volume control problem into a simple height-based automatic stop mechanism.
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
Prevents overfilling by forming an air cushion that restricts the filling volume, ensuring trouble-free operation and reducing the risk of component damage by maintaining the oil level within predefined limits without requiring additional aids.
Implementation Method 1
an air volume enclosed by the housing, and the compressor oil that has been introduced is able to be formed in the receiving volume. Overfilling of the receiving volume is thus prevented in that the air volume enclosed by the housing, and the compressor oil that has been introduced, forms an air cushion in the receiving volume, which air cushion limits the filling of the receiving volume.
