Systems for filtering particles from an airflow are provided. In an embodiment, by way of example only, the system includes a chamber, an airflow and particle inlet, a concentrator, a first outlet, and a second outlet. The airflow and particle inlet is adapted to direct at least a portion of the airflow and the particles into the chamber. The concentrator is adapted to concentrate the particles from the airflow and particle inlet into a space within the chamber. The first outlet is in flow communication with the concentrator and adapted to allow the concentrated particles to exit the system, while minimizing an amount of air exiting therefrom. The second outlet is in flow communication with the chamber and is adapted to allow substantially all of the airflow to exit therethrough.

A butterfly valve (30) in which an actuator (38) is secured to the plate (36). The actuator (38) is carried with the plate (36) when the latter moves. The plate (36) may be revolvable and translatable relative to the shaft (42). The actuator (38) may be used to open and adjust a pilot valve (94) secured to and carried with the plate (36), and to revolve or translate the plate (36) relative to the shaft (42) in order to vary hydrodynamic torque exerted on the plate (36).

Butterfly valves with actuators carried on valve plate

A fluidfoil (78) for use in guiding fluid-borne vehicles has first and second bodies (82, 80) arranged in telescoping relation and collectively defining the leading and trailing edges (18, 20) of the fluidfoil so that the chord length (24) of the fluidfoil is variable. The bodies (82, 80) are rotatable about a shaft (16) defining an axis (14) in fixed positional relation to the leading edge (18), and the fluidfoil (78) is operable under the influence of a relatively moving, surrounding fluid medium (22) to assume an angle of attack which depends on chord length (24).

Control surface structures for fluid-borne vehicles and method for

A butterfly valve adapted for controlled variation in the area of the leading wing of the valve plate. The valve plate is comprised of two parallel plate-like members which are relatively translatable in mutually parallel directions. The relative translational movement further covers or uncovers an open area formed through one of the two members on the leading wing thereof. Movement of the valve plate occurs as either rotational movement of the entire valve plate or relative translational movement between the foresaid members. The type of movement depends on whether the force exerted on the members by a biasing mechanism is exceeded by the torque exerted on the valve plate by a conveyed fluid.

Butterfly valve with biased area reduction means

A flow modulator (48) for a butterfly valve (40) incorporates a first protrusion (64) on the high-pressure side (52) of the modulator and a second protrusion (66) on the low-pressure side (54). The second protrusion (66) is spaced from the leading edge (60) to define a surface portion (88) of the low-pressure side (54). In operation, the second protrusion (66) functions as a flow restrictor that increases pressure in a region (86) of the flow path (44) bordered in part by the second protrusion and the surface portion (88). This increase in pressure serves to minimize the net aerodynamically-induced closing torque exerted on the modulator (46). The height of the second protrusion and its distance from the leading edge are shown to be important design parameters. In addition, the use of a third protrusion (114) for reducing torque drop-off at high rotational angles is disclosed.

Butterfly valve with plural-fence modulator plate

A method for facilitating control of a butterfly valve, butterfly valves (40, 180) adapted for use with the method, and a fluid system (242) incorporating such valves are disclosed. All three use or incorporate butterfly valve structure that provides for relative translational movement (246) between the valve plate (42, 182, 248) and a pivot axis (232) in order to alter fluid dynamic torque exerted on the valve plate.

a balanced butterfly valve method and apparatus having a valve plate pivotally supported within a mounting body. The valve plate is capable of both rotational and translational movement in response to rotation of an input shaft. A spring is provided to resist translational movement of the valve plate. Differential gearing is used to convert rotational movement of the input shaft into rotational and translational movement of the valve plate depending on the relationship between the force exerted by the spring and the torque exerted on the valve plate by the fluid.

Butterfly valve method and apparatus

A method for exploiting the net torque exerted by a conveyed fluid on the valve plate of a butterfly valve to facilitate control of the valve, and a butterfly valve (40) adapted for use with the method are disclosed. The method employs translational movement of the valve plate to facilitate rotational movement of the same and to effect dynamic torque balancing. The butterfly valve (40) employs a differential gear (50) as a mechanical resolver to produce either rotational or translational components of movement depending on whether the net torque exerted by the fluid is sufficiently high to overcome impedance to translational movement.
