摘要： A fluid pulse device includes a piezo actuated valve, a piezo injector, a delivery system, and a control system. The piezo actuated valve has a valve body, a tube, and a piston assembly. The valve body defines a first opening, a second opening, and a valve cavity that is disposed between the first opening and the second opening. The tube extends from the valve body. The piston assembly includes a piston head and a stem that is connected to the piston head. The piezo injector has an injector tip that extends through the first opening. The delivery system is fluidly connected to the piezo injector. The control system is operatively connected to the piezo injector and is configured to actuate the piezo injector to provide a fluid pulse.

摘要： A fluidic oscillator includes a structure having an input port and an output port. A chamber within the structure is configured to channel a fluid from the input port to the output port. A volume of the chamber is configured to change so as to change to change a frequency at which the fluid flows out of the output port.

摘要： The invention relates to a displacement unit (1) of a hydraulic machine, for which the hysteresis is reduced. For this purpose, in the control spool (3) and/or at the control spool (3) a mass body (16) and a spring (17) are arranged, which are excited to resonance vibrations. The vibrations are self-excited and sustained by a partial flow rate of the hydraulic fluid which is modulated periodically. The high frequent vibrations are transmitted over the spring (17) onto the associated control spool (3), thereby reducing the friction and hence the hysteresis.

摘要： An excavation system employing a high-pressure pulsed air jet in combination with a low-pressure high velocity blower for excavating improvised explosive devices or other buried objects. The excavation system may also be employed to operate a pneumatic tool such as a cut-off tool or a chisel. The high velocity blower may incorporate a bifurcated fan duct having two air outlets. The system may include a pressure control module for regulating the from a high-pressure air source to an evacuation valve. The evacuation valve employs first and second valves where the second valve controls the operation of the first valve.

摘要： An improved compacting device for compacting a granular, loosely coherent mass, such as soil-moist cement, for producing end products such as tiles, kerbstones and the like. The compacting device includes a vibrating table and a hydraulic exciter device for driving the vibrating table. The hydraulic exciter device includes a plurality of hydraulic exciters and is configured to drive the hydraulic exciters with excitation displacements of mutually substantially the same amplitude and frequency and in phase with one another. An improved hydraulic exciter for use in the improved compacting device, and the improved compacting device with a single improved exciter of this type are also described.
