摘要： The rotor has a body with recesses formed therein in which airfoil-type blades are secured. The blades have platforms which abut one another to define an annular wall which circumscribes the rotor body. One edge of each of the platforms, which abuts an adjacent platform, has a rectilinear cut-out formed therein. The resulting void constitutes a slot which extracts fluid therethrough, and each void has an evacuating duct in communication therewith for venting the extracted fluid. The voids and ducts bleed off a minimal volume of the fluid handled by the rotor, principally the volume which comprises the secondary flows. These are the secondary flows which, otherwise, would result in the formation of eddies and vortices which are susceptible of eroding the roots of the blades.

摘要： Difficulties in pumping mixtures of gases and liquids are avoided in a rotary machine which both pumps and separates the mixture and which includes a generally tubular, elongated pump housing 10 having a suction inlet 22 at one end, a first outlet 32 for gas at the other end, and a second outlet 58 for liquid intermediate the ends but in close adjacency to the outlet 32. The first outlet 32 is primarily axially directed and the second outlet 58 is primarily radially directed. An elongated rotor 30 is disposed within the housing and is disposed between the ends. The rotor 30 has a length to diameter ratio substantially in excess of one. A plurality of generally axially elongated, radially extending vanes 62 are carried by the rotor 30 and the second outlet 58 is surrounded by a volute 40.

摘要： In order to continuously supply lubricant to compressor bearings independent of attitude, and under varying gravitational forces, an oil supply system (10) includes an oil sump (14), a pump (22), and a suction tube (24). The oil sump (14) is defined at least in part by a pair of intersecting sump walls (16, 18) each of which may comprise a primary wall dependent upon instantaneous compressor attitude. The pump (22) is adapted to supply the compressor with oil (20) while at the same time removing gases from the oil (20) and expelling the removed gases into the oil sump (14). Additionally, the suction tube extends from the pump to a strategic point within the oil sump (14) for drawing oil (20) from the oil sump (14) to the pump (22) in a manner assisting in priming and repriming during brief interruptions in the flow of oil (20) from the oil sump (14).

摘要： The valve has a ported valving element which removes from, and seats upon, a ported valve seat, to open and close the valve to fluid flow through a ported stop plate, and the valving element, in relation to ports in the stop plate, has relieved steps formed therein to create rolling vortices in the through-flowing fluid. Additionally, the valve, in a first embodiment thereof, has two ported buffer plates, however, the latter, vis-a-vis the stop plate ports, have no steps; rather the ports therein are of the same dimension as the ports in the stop plate with which they align or register.

摘要： A centrifugal pump includes a rotating impeller for accelerating low pressure inlet fluid to a substantially tangential high pressure fluid. A pair of floating rotatable shrouds flank opposite axial sides of the rotating impeller. Pressurized hydrostatic bearings back the shrouds to float and support the shrouds in a uniform fashion. Pressurization for the hydrostatic bearings can come from the high pressure fluid side of the pump.
