Solution Overview
Problem
Existing single-line distributors for lubricant distribution are complex, costly, and lack reliability, particularly in terms of precise metering and operation under varying pressures.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional sleeve or shuttle valve is used to ensure single-line distributor function, then the device can operate under pressure, but the structure becomes complex and production costs increase
Solution Approach 1:
The control piston and dosing piston are merged into a single integrated component that performs both control and metering functions simultaneously, eliminating the need for separate sleeve or shuttle valve mechanisms while maintaining operational reliability under pressure
Solution Approach 2:
The control piston serves multiple functions: it acts as both a control element for directing lubricant flow and a dosing element for precise metering, replacing what would traditionally require multiple separate components including sleeves or shuttle valves
2Measurement precision
If a complex single-line distributor design is used, then precise metering can be achieved, but production costs increase
Solution Approach 1:
The control and dosing functions are combined in one piston structure, reducing the number of parts that need to be manufactured and assembled, thereby lowering production costs while maintaining precise metering capability through the integrated design
Solution Approach 2:
The dosing precision is achieved through adjustable geometric parameters of the control piston and dosing chamber rather than through complex mechanical mechanisms, allowing precise metering to be achieved through simpler, more cost-effective manufacturing
3Ease of manufacture
If a simple single-line distributor structure is used, then production costs decrease, but operational reliability deteriorates
Solution Approach 1:
The spring-loaded control piston system automatically responds to pressure changes in the lubricant line, self-regulating the metering process without requiring external control mechanisms, thereby maintaining high operational reliability with a simple structure
Solution Approach 2:
The control piston is positioned by lubricant pressure itself, creating a feedback mechanism where the system automatically adjusts dosing based on actual line pressure conditions, ensuring reliable operation despite the simplified structure
4Adaptability or versatility
If conventional valve mechanisms are used, then the distributor can handle varying pressures, but wear increases and reliability decreases
Solution Approach 1:
The invention replaces conventional mechanical valve mechanisms with a spring-loaded piston system that uses elastic deformation and pressure balancing to adapt to varying pressures, eliminating the sliding contacts and sealing surfaces that cause wear in traditional valves
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
Enables precise and reliable lubricant distribution with a simple structure, reducing production costs and enhancing operational reliability by using a spring mechanism to control piston movement and adjust lubricant volume.
Implementation Method 1
a spring whose first end acts on the control piston and whose second end acts on the metering piston
Implementation Method 2
a spring whose first end acts on the control piston and whose second end acts on the metering piston
Implementation Method 3
a control piston which is in a starting position releases a first lubricant connection between the relief chamber and a pressure channel leading to the dosing chamber and blocks a second lubricant connection between the lubricant inlet and the pressure channel

AI summary
An introducing distributor (1) for distributing lubricant, comprising a lubricant inlet (2a) which is fluidically connected and/or connectable to a lubricant pump, in particular via a lubricant main line, a lubricant outlet (23a, 23b) for transfer of a pre-metered amount of lubricant, a metering space (22), a relief chamber (21) for receiving lubricant, a movably mounted control piston (4) which, in a starting position, opens up a first lubricant connection (3c) between the relief chamber (21) and a pressure duct (20) leading to the metering space (22) and blocks a second lubricant connection (3b) between the lubricant inlet (2a) and the pressure duct (20), wherein, in a working position, the control piston (4) blocks the first lubricant connection (3c) and opens up the second lubricant connection (3b), a movably mounted metering piston (5), and a spring (9), the first end (9a) of which acts upon the control piston (4) and the second end (9b) of which acts upon the metering piston (5).
