摘要： The invention relates to fluid actuator for influencing the flow along a flow surface through ejection of a fluid. By means of a like fluid actuator, a continuous flow is distributed to at least two outlet openings in order to generate fluid pulses out of these outlet openings. Control of this distribution takes place inside an interaction chamber which is supplied with fluid flow via a feed line. Into this interaction chamber there merge at least two control lines via control openings to which a respective different pressure may be applied. Depending on the pressure difference at the control openings, the flow in the interaction chamber is distributed to the individual outlet openings.

摘要： A vortex-controlled variable flow resistance device ideal for use in a backpressure tool for advancing drill string in extended reach downhole operations. The characteristics of the pressure waves generated by the device are controlled by the growth and decay of vortices in the vortex chamber(s) of a flow path. The flow path includes a switch, such as a bi-stable fluidic switch, for reversing the direction of the flow in the vortex chamber. The flow path may include multiple vortex chambers, and the device may include multiple flow paths. A hardened insert in the outlet of the vortex chamber resists erosion. This device generates backpressures of short duration and slower frequencies approaching the resonant frequency of the drill string, which maximizes axial motion in the drill sting and weight on the bit. Additionally, fluid pulses produced by the tool enhance debris removal ahead of the bit.

摘要： Disclosed herein in a MULTI-AND fluid logic circuit comprising essentially of a conventional fluid amplifier having a power source, first and second control channels and first and second output channels. The amplifier is provided with biasing means which is associated with one of the control channels and means are associated with the other control channel for producing a control signal which is a function of a predetermined number of external signals. More particularly, this last named means comprises a plurality of aspirators, each having an input nozzle and an exhaust nozzle and each connected to an enclosed manifold which in turn is in fluid communication with the second control channel of the fluid amplifier. The operation is such that the simultaneous presence of a fluid signal in all aspirators creates a sufficient pressure change to switch the fluid stream in the fluid amplifier from the first output channel to the second output channel.

摘要： A three-dimensional mono-stable proportional device or fluid amplifier capable of simultaneously performing as a digital device and proportional amplifier, i.e., producing a NOR logic function concurrently with the proportional function. The principle of operation is based on the Coanda or Wall effect. The device has two or more outputs, i.e., the outputs have a proportional relationship one with the other, additionally, an output may include a NOR function. The device may be formed from plastic or the like and lends itself to extremely board tolerances in the manufacturing process, i.e., fluid passageways including power ports, control ports, and outlet ports may be molded integrally with the main body (eliminating costly photoetching and lamination) without degradation of performance. The device includes structure for biasing the main stream to one stable position, assuring passage thereof outwardly through a single outlet port or proportionally dividing it between outlet ports, as desired, when the control ports are deactivated, i.e., the Coanda or Wall effect is maintained at all times independent of the stream from the control ports.
