Contracting/Expanding Measuring Chambers TRIZ Cases
- Fuel Meter Piston Alignment via Segmented Shoulders
Segmented shoulders constrain piston position in volumetric fuel meters, preventing misalignment that causes seal wear and measurement inaccuracies.
- Rotary Valve Cartridge for Fluid Loss Reduction
A rotary valve cartridge directs pumping chamber flow to reservoir or outlet conduits via plunger volume changes.
- Hanging Liquid Dispenser With Metered Dosing and Leak Prevention
Segmented inlet and outlet valves prevent clogging while a welded reservoir eliminates leakage for reliable hands-free dispensing.
- Airless Metered Fluid Dispenser with Locking Sleeve
A metered fluid dispenser uses a rotating locking sleeve and biasing element to control nozzle travel for precise volume delivery.
- Valve Block Assembly Sealing Integrity After Autoclaving
Planar sealing surface on valve insert maintains seal integrity after autoclaving without extra components.
- Portable Liquid Dispenser with Compressible Chamber and One-Way Valves
A portable liquid dispenser uses a compressible chamber to displace preset dose volumes through one-way valves for accurate manual delivery.
- Resilient Bellows Dispensing Device for Flexible Packaging
A resilient bellows dispensing device with an adjusting nut enables stepless volume control for flexible liquid packaging.
- Fluid Dispenser Drain Valve for Dip Tube Refill
A drain valve in the bucket connects to the reservoir, allowing fluid from the cup to return when the applicator is reattached.
- Single Actuator Bidirectional Dispensing Mechanism
A single actuator with bidirectional rotation selectively dispenses multiple products through motion converters.
