Progressive Distributor Through-Bore Layout for Compact Lubrication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing progressive distributors are bulky and require complex maintenance due to closely located lubricant outlets, making them difficult to install and maintain.
Innovation Solution
A compact progressive distributor design with concentrically arranged piston bores and lubricant outlets, using a single through-bore for both functions, and a detachable insert or O-ring for sealing, which allows for easier replacement and assembly, and a venting device to ensure proper function and high distribution accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the piston bore and lubricant outlet are located on different planes in traditional progressive distributors, then each function can be independently designed, but the housing block height increases and installation space is consumed
Solution Approach 1:
The patent combines the piston bore and lubricant outlet into a single through-bore structure that extends through the housing block. The first section accommodates the metering piston while the second section serves as the lubricant outlet, both located in the same plane. This merging of functions into a single bore reduces the housing block height and installation space requirements while maintaining independent design capability through the stepped configuration.
2Volume of stationary object
If the lubricant outlet connection is surrounded by other screws due to close proximity of outlets, then the housing block size is reduced, but the outlet connection cannot be removed directly increasing maintenance effort
Solution Approach 1:
The patent segments the through-bore into distinct first and second sections, where the first section has a smaller diameter for the metering piston and the second section has a larger diameter for the lubricant outlet connection. This segmentation allows the outlet connection to be accessed and removed independently from surrounding components, facilitating easier maintenance while maintaining a compact housing block size.
3Adaptability or versatility
If multiple bores are machined into the housing block for piston bores and lubricant outlets, then the distributor functions are achieved, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent merges the piston bore and lubricant outlet into a single through-bore structure with stepped sections. This single bore performs multiple functions: accommodating the metering piston in the first section and serving as the lubricant outlet in the second section. This reduces the number of separate bores that need to be machined into the housing block, thereby simplifying manufacturing and reducing costs while maintaining full distributor functionality.

AI summary
The invention relates to a progressive distributor (1) for lubricant, comprising a housing block (2). The housing block (2) has a lubricant inlet bore, via which lubricant can be introduced into the progressive distributor (1), and multiple lubricant outlets (16), each of which can dispense a metered lubricant quantity to a load connected to the respective lubricant outlet (16). In order to dispense the metered lubricant quantity, the housing block (2) is equipped with multiple metering pistons (6), which are received in corresponding piston bores (4). Each piston bore (4) is paired with two lubricant outlets (16), and the metering piston (6) can be moved in the piston bore (4) and is designed to alternately dispense the metered lubricant quantity to one lubricant outlet (16) or the other. Furthermore, the piston bores (4) are fluidically connected to the lubricant inlet bore, and the piston bores (4) are fluidically connected together via connection bores (10) in order to further conduct lubricant to the other piston bores (4). The piston bore (4) is a through-bore which extends through the housing block (2) and has at least two regions (24, 26), wherein the first region (24) is designed to receive the metering piston (6), and the second region (26) is designed in the form of a lubricant outlet (16).
