Check Valves TRIZ Cases
- Freeze-Resistant Manifold With Pressure-Actuated Expansion Chamber
A freeze-resistant manifold uses a linear actuator to hold a plug against fluid pressure, creating an expandable chamber for internal volume changes.
- Viscosity-Independent Flow Restrictor with Radial Throttle
Radial channel throttling isolates viscosity effects from the closing element, ensuring reliable shut-off across varying fuel viscosities.
- Rectangular Vacuum Valve Sealing Ring with Curved Edges
A vacuum valve sealing ring features a rectangular cross section with diametrically opposite radii of curvature for precise sealing engagement.
- Variable Flow Screen Nozzle for Resin Backwash Adaptability
A variable flow screen nozzle uses a movable ball valve to control fluid passage through a head-mounted screen.
- High-Pressure Fuel Pump Flat Valve Circumferential Flow Noise Reduction
A flat valve design with a liquid damper chamber manages circumferential fuel flow to reduce pressure pulsations and noise in high-pressure supply systems.
- Vehicle Pneumatic Circuit Tire Repair Unit
A repair unit connects to a vehicle pneumatic circuit to inject sealing fluid into inflatable articles.
- Sewer Ventilating Valve Wear Reduction via Pin Relocation
Relocating guide pins to the inner ring eliminates lid friction, reducing wear on the sealing membrane during pressure fluctuations.
- Polymer Microvalve with Magnetic Actuation
A polymer microvalve uses magnetic forces to vertically move a plug for fluid control.
- Suction Hose Fitting with Manual Release Valve
Segmented housing and pressure relief valves enable manual flushing of clogged filters without water retention loss.
- Tire Pressure Control Device with Microprocessor and Valve
A tire pressure control device uses a microprocessor to automatically adjust inflation via an integrated valve.
- Actuation Chamber Check Valve Reduces Chatter Wear
A check valve assembly uses an actuation chamber to bias the piston assembly open before inlet pressure reaches cracking levels.
- Hydraulic Overpressure Valve Asymmetric Spring Stabilization
Asymmetric spring arrangement stabilizes cone element in hydraulic overpressure valve to prevent swinging motion.
- Removable Partition Drain Trap for Easy Cleaning
Segmented partition design resolves cleaning access issues in L-shaped storage spaces while maintaining structural stability.
- Flow Limiting Duct Vent Valve Overpressure Shutoff
A flow limiting duct vent valve vents pressurized air when pressure differential exceeds a first threshold.
- Dual Disk Check Valve Slotted Stop Bar Design
A dual disk check valve uses a mechanical stop with rectangular bars to define a slot, reducing spring constant and distributing bearing stresses.
- Disposable Slide Valve for Urine Bag Flow Control
A disposable slide valve unit regulates urine flow through an axially displaceable male part nested within a female component.
- Control Valve Integrated Check Valve Pressure Peak Protection
Integrated check valve with elastically deformable closing part blocks pressure peaks while maintaining low pressure drop and high reliability.
- Spring Loaded Check Valve Buckling Spring Water Hammer Mitigation
A spring return check valve uses a buckling spring with offset eyelets to control disc movement and mitigate water hammer.
- Electronic Module Locking Mechanism for Vehicle Wheel Sensors
A latch plate with locking teeth engages transversal detents on a rigid tube to secure an electronic module.
