Multiple Way Valves TRIZ Cases
- Modular Fluidic Device Segmentation for Clogged Passage Replacement
Segmenting the base member into independent fluid units allows replacing only clogged passages without removing attached piping, reducing labor and costs.
- Hydraulic Changeover Valve for Parallel Lubrication Systems
Dual-spool modular valve design enables simultaneous pressurization and venting to resolve slow fluid return in high volume systems.
- Reverse Out Valve Bypass Region for Swabbing Control
A reverse out valve uses a bypass region to allow fluid flow around the valve element during axial movement.
- Faucet Cartridge Radially Offset Key Rotation Resistance
Radially offset keys on a faucet cartridge prevent rotation within the valve body, resolving trade-offs between reliability and manufacturing complexity.
- Rotatable Valve Spool Angled Seals Assembly
Angled seals on a rotatable valve spool eliminate face sealing O-rings, reducing manifold complexity and improving reliability.
- Central Fixation Valve Pneumatic Assembly
A pneumatic valve uses a single mechanical fastener to secure the shaft and body, simplifying the rotatable disc assembly.
- Sliding Seal Assembly for Dirty Fluid Pressure Regulation
Elastomer seals reduce friction and dead band in a sliding seal assembly, enabling reliable pressure regulation in abrasive downhole fluids.
- Hydraulic Valve Port Design for Lateral Force Balance
Segmented flow paths balance pressure around the spool to eliminate friction and wear in automatic transmission valves.
- Variable Displacement Compressor Valve Startup Efficiency
A displacement control valve manages refrigerant flow through a stepped valve seat geometry.
- Hydraulic Coupler for Subsea Riser Isolation
A hydraulic coupler shifts fluid supply between two sources using a male stab member to block external contamination.
- Spindle Receptacle Slots Prevent Valve Self-Adjustment
Segmented slots and prestressed spring elements in the spindle mount prevent unintentional self-adjustment of the upper valve part under thermal stress.
- Single Lever Mixing Cartridge Axial Stop Adjustment
Ultrasonic deformation of housing axial stops compensates for disc stack tolerances to ensure reliable cartridge assembly.
- Vacuum Filter Distributor Valve Body Sealing
A distributor valve body partially covers a rotating filter shaft to create a sealed interface.
- Three-Way Valve for Pressurized Liquid Dispenser Venting
A three-way valve switches between dispensing and venting positions to manage internal pressure in liquid containers.
- Segmented Valve Sleeve Reducing Compressed Air Leakage
Segmented sleeves with internal seals eliminate strict indexing requirements to prevent compressed air leakage and reduce production costs.
- Fan-Shaped Multi-Way Valve Sealing for Compact Oil Well Measurement
A multi-way valve uses fan-shaped flow channels and a floating gating ring to form reliable sealing pairs.
- Gate Valve Sequential Flow Control for Resin Leakage
Sequential pin and sleeve movement prevents simultaneous injection and discharge openings, suppressing air contamination in molded products.
