摘要： An anti-backflow eductor has a resilient sealing sleeve disposed on a water port defining blind end tube. The sleeve has a thinner wall cross section at a discharge end to enhance sealing while facilitating increased water flow. The ports in the blind end tube extend into a radial tube flange at the tube's inlet end to facilitate water flow out of the ports between the sleeve and tube. A tapered seat in the housing, together with cross bars in the vents, reduces the air vent cross section and relative motion between sleeve and housing to reduce sleeve wear. The eductor comprises an anti-backflow housing and a venturi housing coupled together for relative rotation but being inseparable under normal conditions to inhibit venturi use without the anti-backflow function of the anti-backflow housing.

摘要： A method for applying a lateral support load to a jet pump slip joint. The method includes positioning an ovalization device around the diffuser and actuating the ovalization device to apply a predetermined load to the slip joint which creates an oval deformation of the diffuser. The force applied by the ovalization device creates a plastic strain in the diffuser wall which permits the diffuser to maintain an oval shape, and an elastic strain in the wall of the inlet mixer. The elastic deflection of the inlet mixer which is restrained from its original shape applies a lateral preload force to the diffuser at the area where the diffuser has a reduced diameter due to the oval deformation. This lateral preload force maintains a rigid contact between the inlet mixer and the diffuser collar to prevent oscillating motion and suppress FIV.
摘要翻译：一种用于将横向支撑载荷施加到喷射泵滑动接头的方法。该方法包括将椭圆形装置定位在扩散器周围并致动椭圆形装置以向滑动接头施加预定的载荷，从而产生扩散器的椭圆形变形。由椭圆形装置施加的力在扩散壁中产生塑性应变，其允许扩散器保持椭圆形状，并且在入口混合器的壁中产生弹性应变。入口混合器的弹性挠曲受限于其原始形状，在扩散器由于椭圆形变形而具有减小的直径的区域向扩散器施加横向预载荷力。该侧向预紧力保持入口混合器和扩散器套环之间的刚性接触，以防止振动运动并抑制FIV。

摘要： A jet pumping device includes an injection nozzle (1) intended for injection of a working fluid, placed in a line (3) including from upstream to downstream, a substantially cylindrical barrel (4), a convergent neck (5), a mixing channel (6) and a diffuser (7). The nozzle is placed at the end of a nozzle holder (9) on the longitudinal axis of the line, the pumped fluid circulates in an annular space (3) contained between the barrel (4) and the outside of the nozzle and of the nozzle holder, and the orifice of the nozzle has the longitudinal axis as the axis of symmetry. The device includes of one of the following combinations: a) the nozzle holder has, in its inner channel, an element (21; 22) for rotating the working fluid stream in the nozzle and a mechanism (12, 13, 14) for rotating the nozzle around the longitudinal axis, the mechanism being independent of the energy of the working fluid or of the pumped fluid, the nozzle rotating in the opposite direction to the direction of rotation of the working fluid stream; b) the nozzle holder has, on its outer surface, an element (24) for rotating the pumped fluid stream, such as blades inclined in relation to the longitudinal axis; c) the nozzle holder has, on its outer surface, an element for rotating the pumped fluid stream, such as blades inclined in relation to the longitudinal axis and, in its inner channel, an element for rotating the working fluid stream in the nozzle.

摘要： A hybrid vacuum pump comprising an ejector type compressed air-operated vacuum pump. Such pump comprises a housing having an inlet for compressed air, a second inlet connectable to the enclosure to be evacuated, and a discharge outlet. The incoming compressed air being divided into at least two parallel streams by a multiple-outlet chamber, each stream of compressed air passing through at least two nozzles arranged in series, intermediate chambers between successive nozzles of each parallel stream being provided separately for each stream. Pressure-operated valves being provided to automatically prevent flow of gas being evacuated to some of said nozzles as progress is made in producing the desired vacuum, and thus to increase air flow in the remaining nozzles for the achievement of a high vacuum. The pump being characterized by the use of a single body structure being used to support multiple nozzles having different forms.
