Embodiments of apparatus for controlling the movement of matter, including but not limited to one-way fluid valves, are disclosed. The apparatus may include a transition nozzle, a funnel nozzle, and a reverse flow blocker arranged in series in a case. A counter-flow area may be disposed about the funnel nozzle. The apparatus may permit matter to flow in a first direction, and discourage or prevent flow in a direction reverse to the first direction. Control over the flow of matter also may enable matter to be harvested, sorted, separated or combined with injected matter.

A check valve includes a valve body having a flow bore which extends between the inlet and outlet ends of the body, a cavity which intersects the flow bore, and an opening which is connected to the cavity. A body cap is removably secured in the opening, and a seat cartridge is configured to fit through the opening and be slidably received in the cavity. The seat cartridge has an open first end which is aligned with the opening, a second end which is located opposite the first end, a chamber which extends between the first and second ends and defines an inner wall of the seat cartridge, a first bore which extends between the chamber and an inlet bore portion, a second bore which extends between the chamber and an outlet bore portion, and a valve seat which is formed on a portion of the inner wall that surrounds the first bore. A retainer ring is positioned in the valve body between the body cap and the first end of the seat cartridge, and a flapper is pivotally connected to the retainer ring and is pivotable through the chamber between a closed position in which the flapper is positioned against the valve seat and an open position in which the flapper is displaced from the valve seat.

A wetting fluid applicator unit for applying wetting fluid to pressure relief valves during packaging of product, such as roasted coffee, with a packaging system. The wetting fluid applicator unit includes an unpressurized wetting fluid reservoir which delivers wetting fluid to plural fluid supply circuits. One fluid supply circuit charges a spray head with wetting fluid while the other fluid supply circuit is replenished with wetting fluid from the unpressurized reservoir. The wetting fluid applicator unit ensures continuous flow of wetting fluid to the spray head while enabling replenishment of the reservoir during continuous operation of the packaging system.

A monolithic pressure regulator may comprise a boding comprising a base wall, an end wall, and a side wall, a cavity within the body, an input port in fluid communication with the cavity, an output port in fluid communication with the cavity, a first vesicle configured to regulate a flow of fluid through the input port into the cavity at a source pressure to exit through the output port at a regulated pressure, wherein the first vesicle comprises a first vesicle wall contiguous with a bulkhead and at least one of the base wall or the end wall.

Systems and methods for modulating delivery of a fluid medium to a selected site within a patient's body are described. A system includes a syringe for injecting the fluid medium, a delivery catheter including a conduit for delivering the fluid medium from outside of the body to the selected site within the body, a diversion reservoir configured to receive a portion of the fluid medium, and a flow diverter assembly disposed in a fluid medium flow path between the syringe and the delivery catheter. The flow diverter assembly is configured to divert the portion of the fluid medium from the chamber of the syringe away from the delivery of the medium through the delivery catheter conduit during injecting with the syringe. The flow diverter assembly simultaneously increases fluid medium flow resistance with increasing pressure level of the fluid medium passing into the flow diverter assembly.

A system for modulating delivery of a fluid medium includes an injector for injecting the fluid medium during an injection cycle, a delivery catheter including a conduit for delivering the fluid medium, a manifold disposed in a fluid medium flow path between the injector and the delivery catheter, and a pulsatile generator. The pulsatile generator is configured to apply a pulsatile force to the fluid medium defined by a plurality of duty cycles during the injection cycle, each of the duty cycles including a first pressure level and a second pressure level that is lower than the first pressure level.
