    Abstract: A fluid discharge apparatus includes a storage chamber, a moving body, a drive mechanism, and a coupling member. The storage chamber includes a discharge port to discharge the fluid. The moving body includes a leading end portion facing the discharge port inside the storage chamber. The drive mechanism is positioned on the opposite side of the moving body to the discharge port, and performs an operation to reciprocate the moving body. The coupling member couples the moving body to the drive mechanism such that the moving body is attachable and detachable. The coupling member includes a biasing section to apply an elastic force in a direction to move the moving body toward the drive mechanism, and, while pressing the moving body against the coupling member, to support the moving body in a state in which the moving body is capable of elastic displacement in a direction toward the discharge port.

    Abstract: A fuel electro-injector for a fuel injection system for an internal combustion engine, having an atomizer equipped with a nozzle and a valve needle defining a discharge section that is annular and has a width that continuously increases as the opening stroke of the valve needle proceeds. The opening stroke is directed outwards and is caused, in a proportional manner, by the operation of an electric actuator. The electro-injector has a high-pressure environment with an annular passageway around the lateral outer surface of the valve needle to supply fuel to the discharge section, and a low-pressure environment, which communicates with a fuel outlet and is separated from the high-pressure environment by a dynamic seal between the valve needle and the nozzle. The electro-injector is provided with a hydraulic connection between the electric actuator and the valve needle, with a pressure chamber axially delimited, on one side, by the valve needle and, in use, is filled with fuel that, once compressed, axially pushes the valve needle along the opening stroke. The hydraulic connection is placed in the low-pressure environment, so that the pressure chamber only communicates with this environment.

    Abstract: A synthetic jet actuator and a method for optimizing a synthetic jet actuator to meet operating requirements and physical constraints may include estimating dimension and a resonance frequency of an air cavity of the synthetic jet actuator, and using the estimated resonance frequency to the estimate dimensions of a piezoelectric actuator of the synthetic jet actuator. Individual simulations of the air cavity and piezoelectric actuator, and a coupled simulation may be performed using the estimated dimensions, and the dimensions may be revised and simulations re-executed to match the resonance frequencies of the air chamber and the piezoelectric actuator. The method maybe yield a synthetic jet actuator having a resonance frequency of the piezoelectric actuator that is approximately equal to a quarter-wavelength resonance frequency of the air cavity.

    Abstract: An oscillating spray nozzle and related methods for providing spray patterns in a variety of oscillating patterns by driving movement of the nozzle with a progressing cavity displacement motor. By varying the design of the progressing cavity displacement motor, a variety of spray pattern geometries can be generated and a speed of the nozzle as it travels through the spray pattern geometries can be controlled. The oscillating spray nozzle can include a housing enclosing a progressing cavity motor that is operably connected to a spray nozzle. The progressing cavity motor includes a rotor member that is caused to rotate and oscillate within a stator member. The rotor member is operably linked to the spray nozzle, whereby the movement of the rotor member is communicated to the spray nozzle.
