Check Valves TRIZ Cases

A pressurizable adapter integrates a wide Schrader valve core into a narrow Presta stem to increase air flow cross-section.

External fabric bonding secures the vent flange, eliminating heavy internal metal components that cause sagging and tearing of the collapsible tank wall.

Replacing metal housings, this plastic anti-drain valve integrates snap-fit fixation to reduce manufacturing complexity while maintaining fluid-tight sealing.

A twin power valve assembly uses an integrated balance piston to equalize hydraulic pressure across left and right brake circuits.

Closed syringe system rehydrates powder in microgravity using controlled fluid flow, preventing gas bubbles that compromise system integrity.

A monolithic T-shaped body houses a pressure responsive ball valve to relieve excess fuel line pressure, reducing device complexity and inventory variety.

A pistonless media control valve uses a flexible diaphragm to actuate the plunger assembly without sliding seals.

Airfoil lift elements on check valve petals generate upward force to counterbalance petal weight, reducing washer element wear and housing contact.

Merging radial and axial sealing into one component eliminates tilting jamming risks in compressed air overflow valves.

Clamping bracket prevents uncontrolled deformation and premature damage in compressed air systems.

An oval contour on the support seat minimizes wear by distributing contact pressure, preventing continuous injection in common rail systems.

A gas injection valve adds a thermoplastic seal to prevent elastomeric swelling and leakage under carbon dioxide pressure exceeding 60 bar.

A pipe disconnector valve uses a shared spring to maintain equilibrium, preventing unnecessary opening during inlet pressure variations.

Integrated relief and check valve functions in a single regulator assembly prevent freezing and blocking at low temperatures.

Fatigue-resistant mechanical means reduce radial play in hydraulic valve tappets to minimize oscillations.

Discharge nozzle unit positions elastic sleeve for reliable backflow prevention while reducing manufacturing costs.

A subsea pressure equalizing valve balances internal casing fluid against external hydrostatic loads using a gravity-closed mechanical design.

A flexible sleeve valve creates an airtight passage for inflating gas in evacuation units.

A valve assembly uses pressure differences to automatically expand openings and flush debris from clogged flow regulating units.

A non-return valve uses a two-component injection molded elastic soft seal on a hard plastic closing body to ensure reliable gas tightness.

Above-grade dual plate check valve prevents fluid loss by automatically closing upon pipe breakage.

A pressure compensation unit uses a gas-permeable filter diaphragm to enable ambient air flow through a housing channel.

Tubular bumpers on the flap absorb shock forces upon opening, preventing cracking and extending component life.

A dual threshold check valve uses independent sealing elements to manage fluid passage in opposing directions.

A pressure relief valve uses a linear actuator to retract a ball, allowing fluid flow through the passage.

A compliant petal stop absorbs dynamic impact loads, preventing petal fractures and extending check valve lifespan.

A pneumatic device uses a sliding piston to control fluid injection and exhaust for tire inflation.

An inverted bowl poppet valve lifts via atmospheric pressure against a soft annular seat, preventing leakage from thermal deformation in sewage systems.
