Check Valves TRIZ Cases

Merging two check valves into one unit reduces modulator block volume and eliminates complex multi-part assembly steps.

Electrical probe detects trapped water above clapper body to prevent pressure buildup that blocks valve opening.

Support surfaces separated by narrow grooves prevent unintended closure and maintain sealing across pressure variations.

Repositioning the relief valve seat face intersection suppresses cavitation bubbles that cause erosion during high-pressure fuel release.

A conical bearing face mounts the cartridge bushing to combine force vectors and suppress play during lever actuation.

Relief openings in the valve element create pressure differentials that minimize switching hysteresis, preventing fuel tank overfilling during refueling.

Partition walls segment the exhaust channel into sub-channels, preventing large vortex formation that causes pressure losses.

A mechanical valve applicator unit uses vacuum suction to transfer adhesive-backed pressure relief valves from a tensioned liner onto packaging surfaces.

Segmented valve stem assemblies allow targeted replacement of corroded components, reducing repair time and cost compared to full assembly swaps.

A flow check valve in a tank vent port opens for air but closes under fluid pressure.

A throttle valve generates adiabatic expansion cooling to offset adsorption heat, maintaining stable temperature and storage capacity.

A hydraulic non-return valve uses a one-piece closing element with an integrated projection for mechanical unlocking.

An inverted spin-on filter system uses a drain pump and check valves to remove residual fluid from the element before removal.

Linear valve head with a skirt-like wall eliminates debris accumulation in hinges while reducing force required for sealing.

An undiverted axial passage keeps filtered water flowing during spray activation, preventing cross-contamination from hot and cold supplies.
