摘要： In a separation device for separating particles from a liquid, which is present in a container (1), a centrifugal rotor (7) is rotatable around a vertical rotational axis (R). The centrifugal rotor (7) has a tubular inlet member (8), which extends down into liquid to be treated and which upon rotation of the centrifugal rotor forms a pumping member adapted to pump liquid upwardly and into the centrifugal rotor. According to the invention the rotatable inlet member (8) is surrounded by a non-rotatable wall (12), a sealing device being adapted to seal between the rotatable inlet member (8) and the non-rotatable wall (12). Thereby is avoided that liquid is pumped upwardly on the outside of the inlet member. Furthermore, a smallest possible part of the outside of the inlet member (8) can be in contact with liquid, independent of the level of the liquid surface in the container (1).

摘要： Rotary fluid handling apparatus employing a wheel (34) to provide multi-stage compression or expansion. A wheel (34) having a first set of vanes (36) includes a shroud (38) about those vanes with a second set of vanes (40) outwardly of the shroud. One set of vanes provides for law specific speed flow while the other set of vanes provides for high specific speed flow. A transfer passage (22) interconnects the outlet of the first stage with the inlet of the second stage. The difference in temperature between the inlet flow to the system and the outlet flow from the system may be exchanged (52) to increase efficiency. The multi-stage wheel and associated passages may be configured for either compression or turboexpansion.

摘要： A regenerative turbomachine has a rotatable bladed impeller (1) and an annular housing (3) surrounds the impeller (1) and defines a topological flow channel for a working fluid. There is also an inlet port (4) for admitting a working fluid to the housing (3) and an outlet port (5) spaced circumferentially of the impeller (1) from the inlet port (4) by which the working fluid can leave the housing (3). Guide means is also provided for guiding the working fluid entering the inlet port (4) through a slip flow path and a counter-flow path which follow respective spiral paths in opposite directions around the toroidal flow channel. Each flow path makes a number of successive passes through the impeller (1) and each successive pass is spaced circumferentially from the other passes.

摘要： The present invention relates to a reaction-type steam turbine. More specifically, the present invention relates to a reaction-type steam turbine that has guide blades mounted on a turbine shaft located between disk blades and a steam inlet tube to divert steam introduced into a housing from the steam inlet tube to the disk blades, thereby preventing a vortex phenomenon within the housing, and rotates the guide blades by means of the pressure of the introduced steam to rotate the turbine shaft, thereby reducing the initial load against the rotation of the turbine shaft and doubling the rotational output of the turbine shaft along with the rotation of the disk blades. To achieve this, provided is a reaction-type steam turbine that comprises: a housing having steam inlet and outlet tubes formed on opposite sides thereof, respectively, and having a space formed therein; and a turbine shaft installed to pass through the space of the housing and having a plurality of disk blades mounted thereon, wherein guide blades are shaft-coupled to the turbine shaft between the passage of the steam inlet tube and the disk blades to guide steam introduced into the space of the housing through the steam inlet tube to the disk blades.

摘要： The invention relates to an ecological thrusting device enabling optimum thrust independent from the outside environment. It consists of a special Francis turbine (1) from which the fluid is axially ejected at the outlet of the vane (1'), at a relative speed W
2t , and is collected in a defined free space of a straight radial pump (2). Under the action of the centrifugal force, the limit of the current lines forms a fixed virtual barrier Y
t , thus preventing the centrifuged fluid from reaching the bottom of the pump in the free space area MNBCPQ, thereby eliminating the antagonistic force exerted on said zone. As a result, the thrusting force exerted on the turbine by the fluid remains intact. As the fluid leaves the pump, it is axially reinjected at a relative speed W
2p into a tank (4) for resupplying the turbine. There is therefore an energy exchange between the pumps and the turbine that form a closed circuit, the entire system being driven by a motor (10). It is shown that the thrust force P = (1/2) pπω
2 r
4 ; p being the density of the centrifuged fluid in en Kg/m
3 ; ω being the angular speed of the turbine in rad/s; and r its radius in metres and P in Newtons. The calculation shows that the amount of thrust generated is very high; said thruster can be used to generate mechanical energy anywhere in space, and especially to drive the most highly efficient flying machines.-
