A shifting deposition source and UV curing in one chamber improve large-substrate thin-film uniformity while cutting footprint and tact time.

A collapsible outer piece, plug, and separate cap create two sealing stages that reduce air loss and simplify inflation and deflation.

A universal housing with quick connectors and interchangeable flow controls cuts molds and parts while meeting regional backflow rules.

A cradle-supported ball and laterally positioned spring prevent coil blockage, enabling accurate sealing and rapid full-flow pressure relief.

A tapered needle and controlled lift stabilize differential-pressure throttling, preventing hunting noise and erratic refrigerant pressure.

Two center-hinged swing flaps cut opening pressure and pressure drop in boiler exhaust ducts while preventing flue gas backflow.

Negative-pressure suction and an adjustable valve help seated users with poor digestive function excrete more comfortably while easing caregiver burden.

Axially spaced flapper seals in inlet and outlet pipes block convection currents, cutting standby heat loss from water heaters.

A check-valved bypass feeds refrigerant from the liquid line to the harvest line to sustain mass flow and suction pressure in low-charge ice systems.

A vortex regulator with staged pressure reduction and heat exchange cuts CNG from 3000 psig to delivery pressure without freeze-up.

A one-piece flexible spout uses inclined flanks and a pressure-sealed slit valve to prevent leaks while opening easily under lip pressure.

An integrated non-return valve in the inlet assembly blocks reverse water flow, protecting fresh water lines while reducing parts and assembly.

An elastic insert check valve simplifies household appliance assembly while maintaining one-way fluid sealing with lower precision requirements.

A cross-slit valve with a perforated baffle prevents backflow and clogging in fluid dispensers handling viscous or particle-laden liquids.
