Flow Diverter for Pneumatic Motor Inlet Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The positioning of the air inlet close to vane lifter ports in traditional pneumatic tools limits the type of motor that can be used, restricting flexibility and power control.
Innovation Solution
A flow diverter is disposed in the plenum area of the motor cylinder chamber, acting as a barrier to direct air or fluid to vane lifter ports before it enters the cylinder chamber, allowing for flexible inlet positioning and power regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air inlet is positioned close to the vane lifter ports, then the vanes are deployed before significant air enters the cylinder chamber, but the type of motor that can be used is limited
Solution Approach 1:
The air inlet system is segmented into separate functional zones: a first port for vane lifter ports and a second port for the cylinder chamber inlet. The flow diverter further segments the airflow path, directing air selectively to either the vane lifter ports or the cylinder chamber inlet based on operational needs. This segmentation allows independent optimization of motor configuration and vane deployment timing.
Solution Approach 2:
A flow diverter is introduced as an intermediary component between the air inlet and the motor chambers. This flow diverter acts as a mediator that controls and directs airflow to different destinations (vane lifter ports or cylinder chamber inlet), enabling flexible motor configurations while maintaining reliable vane deployment through controlled airflow timing.
2Reliability
If the air inlet is positioned close to the vane lifter ports, then early vane deployment is achieved, but power control of the tool is limited
Solution Approach 1:
The flow diverter is designed to be movable or adjustable, allowing dynamic control of airflow distribution. By adjusting the flow diverter position, the operator can regulate the amount of air reaching the cylinder chamber inlet while maintaining sufficient air flow to the vane lifter ports for proper vane deployment. This dynamic adjustment provides power control capability without compromising vane deployment reliability.
Solution Approach 2:
The system enables parameter changes in airflow distribution by using the flow diverter to vary the proportion of air directed to different chambers. This allows adjustment of power output parameters while maintaining the critical parameter of proper vane deployment timing through controlled air flow management to the vane lifter ports.
3Volume of moving object
If the air inlet is positioned close to the vane lifter ports, then compact design is achieved, but flexibility in inlet positioning is limited
Solution Approach 1:
The invention resolves the spatial constraint by adding a dimensional aspect to airflow control through the flow diverter mechanism. Instead of being constrained by physical proximity in a single dimension, the system uses the flow diverter to create multiple airflow pathways and control dimensions, allowing the air inlet to be positioned optimally for compact design while maintaining flexibility in how air is distributed to different motor components.

Function Achieved in This Case
Enables the use of various motor configurations and precise control of air or fluid flow, enhancing the operational flexibility and power management of pneumatic tools.
Implementation Method 1
The flow diverter acts as a barrier between a main inlet to the motor and an inlet to the cylinder chamber, and directs air or fluid to vane lifter ports of the motor before the air or fluid flows to the inlet to the cylinder chamber
Implementation Method 2
The flow diverter can serve to regulate air or fluid flowing into the cylinder chamber to control power of the tool

AI summary
The present invention relates broadly to a flow diverter disposed in a plenum area of a motor cylinder chamber (also referred to as kidney ports). The flow diverter acts as a barrier between a main inlet to the motor and an inlet to the cylinder chamber, and directs air or fluid to vane lifter ports of the motor before the air or fluid flows to the inlet to the cylinder chamber. In addition, the flow diverter can serve to regulate air or fluid flowing into the cylinder chamber to control power of the tool. The flow diverter allows for numerous options of where the main inlet to the motor can be positioned and provides a means of regulating the air or fluid flowing into the cylinder chamber.
