Check Valves TRIZ Cases
- Shear Seal Check Valve for Dirty Fluid Reliability
Stationary shear seal elements resist debris fouling in dirty fluids, maintaining reliability without complex external controls.
- Hydraulic Braking Check Valve with Low Modulus Spring
A hydraulic braking check valve uses a low elastic modulus spring to reduce pushing force while preventing fluid leakage at the connecting hole.
- Anti-siphon Device Pressure Loss Reduction
Air-inlet sealing diaphragm with offsetting spring manages fluid flow and system pressure.
- Segmented Inflation Adapter for Rapid Tire Valve Connection
Segmentation of the nozzle body and sleeve enables rapid assembly, preventing gas leakage during disassembly.
- Piston Pump Movable Annular Disk Throttle for Brake Systems
An external movable annular disk throttles fluid flow, lowering internal pressure and drive power in vehicle brake systems.
- Combined Check and Relief Valve for Marine Tilt Trim
A combined check and relief valve uses a resilient member to bias a relief valve member against a seat, enabling fluid flow when pressure exceeds the target.
- Stroke Controlled Balancing Device for Hydraulic Braking Systems
A stroke-controlled balancing device with a sliding valve reduces axial size in hydraulic braking systems.
- Aircraft Check Valve Leaf Spring Stop Damping
Resilient damping elements between flappers and leaf spring stops dissipate impact energy, reducing peak forces on aircraft check valve components.
- Check Valve Segmented Sealing for Foreign Matter
Segmented seals and an inlet filter resolve sealing reliability issues caused by foreign matter in check valves.
- All-Metal Pressure Relief Valve with Lapped Seals
A pressure relief valve uses rigid metal sealing surfaces lapped to high flatness and smoothness for reliable gas containment without elastomers.
