Fluid-Delivery Valves TRIZ Cases
- Lubricant Reservoir Shut-Off Valve for Overfill Protection
A follower-actuated shut-off valve stops reservoir refilling at a set lubricant level, preventing overfill stress and maintaining reliable supply.
- Aerosol Airflow Valve Layout for One-Handed Adjustment
An axial toggle valve layout lets users adjust aerosol airflow with one hand while matching different suction resistance preferences.
- Timed Self-Closing Valve Mechanism With Adjustable Flow Control
A nested delay piston and flow adjustment screw give self-closing taps precise shutoff timing, easier assembly, and controllable water flow.
- Injection-Molded Sealing Plates With Stronger Fiber-Reinforced Weld Lines
Oblique movable guide elements redirect melt flow so fibers cross weld lines, strengthening injection-molded sealing plates.
- Ball Check Valve Slurry Transfer to Prevent Pump Clogging
Operating a ball check valve within a defined slurry flow formula prevents clogging, stabilizes pumping, and reduces cleaning waste.
- Single Lever Faucet Hot Water Auto Shut-Off Mechanism
A single lever faucet uses a torsion spring to automatically shut off hot water flow when the handle is released.
- Gravity-Driven Filling Valve Sleeve Design
A weighted valve sleeve moves between open and closed positions using gravity alone to seal liquid and air outlets without springs.
- Delayed Closing Valve Instant Flow Interruption Mechanism
A secondary push-button valve applies network pressure to the main piston, instantly interrupting water flow in delayed closing valves.
- Delayed Tap Valve Spring-Loaded Piston Assembly
A delayed tap valve uses a spring-loaded piston to control water flow timing through a tubular tail mechanism.
