摘要： A turbo type centrifugal pump is provided in which an angular oscillator is angularly oscillated so that fluid in a radial through hole receives centrifugal force. The angular oscillator is used in combination with a resonance oscillation motor that generates angular oscillation. The resonance oscillation motor is incorporated in the pump so that the pump structure and the drive mechanism are integrated. This reduces the size of the pump. Since the angular oscillation is a reciprocating rotation within an oscillation range less than 360°, a suction pipe can be connected to the radial through hole used in the angular oscillation. This eliminates the necessity for providing a shielding structure.
摘要翻译：提供一种涡轮式离心泵，其中角振荡器角度振荡，使得径向通孔中的流体接收离心力。角振荡器与产生角振荡的共振振荡电机结合使用。谐振电动机并入泵内，使得泵结构和驱动机构一体化。这样可以减小泵的尺寸。由于角振荡是在小于360°的振荡范围内的往复旋转，所以可以将吸入管连接到用于角振荡的径向通孔。这消除了提供屏蔽结构的必要性。

摘要： A nutating drive comprising a housing with a rotor mounted for axial rotation in the housing and an elongated nutating bar retained at one end thereof in a rotary bearing which is connected to the rotor via a drive coupling at a position offset from the rotor axis for imparting nutational movement to the bar about a geometric center of nutation with axial rotation of the rotor. The drive coupling which connects the nutating bar bearing to the rotor is comprised of a flexible sheet support having outer edges secured to the rotor which permits limited pivotal movement of the bar bearing relative to the rotor. This flexible sheet support may be provided in the form of a single flexible disk or as multiple flexible support strips. In either case, support is provided with at least one undulation extending in the radial direction to enhance pivotal flexibility.

摘要： A nutating drive with hermetic seal which includes a housing with an internal wall and a nutating bar passing through an opening in the wall. A flexible tubular diaphragm seal surrounds the bar and is sealed at one end to the wall about the wall opening and is sealed at its other end to the bar for providing a hermetic seal for the wall opening. A universal joint support mechanism connects the bar to the housing for gimbaled non-axial rotational support of the bar in the housing. An axially rotatable rotor is mounted for axial rotation in the housing and the bar is pivotally connected at one end to the rotor at a position offset from the rotor axis for imparting nutational movement to the gimbaled bar about a geometric center of nutation with axial rotation of the rotor. The tubular diaphragm has a conical configuration tapered from a maximum diameter at the wall and to a minimal diameter at the bar end and the tubular seal encloses the geometric center of the bar. The tubular diaphragm seal may have a bellows configuration. A torsion tube which is very flexible in torsion is coaxially received over the bar with one end of the flexible torsion tube circumferentially sealed and secured to the bar and the other end of the torsion tube circumferentially sealed and secured to the minimal diameter end of the tubular diaphragm seal.

摘要： A pump housing is substituted for the food container of a blender. The blender blades act as a pump impeller and cause liquid to flow from a housing inlet, through the housing, and through a housing outlet. The pump housing therefore modifies a blender into a portable, multipurpose pump apparatus that moves liquid from one to another location.

摘要： The hydraulic machine comprises an outer rotor, rotatably mounted around a longitudinal axis and connected, through an input shaft, to a driving motor, and an inner rotor mounted at the interior of the outer rotor, rotatable around a transverse axis, and connected, through a gear drive, to an auxiliary shaft coaxial to the input shaft. A hydraulic circuit is arranged at the interior of the inner rotor, and it presents an active circuit consisting of a pipe winding. The ends of the hydraulic circuit are connected, through rotary connections, to a fixed outflow and a fixed inflow connection. Upon rotation of the outer rotor and of the inner rotor around their respective axis, the inner rotor is subjected to a field of accelerations of Coriolis which generates between the ends of the active circuit a substantially sinusoidally varying pressure difference.
