    摘要： The present invention relates to an apparatus for converting rotation into fluid flow and/or fluid flow into rotation. The apparatus comprises a first coiled fluid conduit and a second coiled fluid conduit and a fluid separator for separating a first fluid from a second fluid having a second density different from the first density. The fluid separator is configured in such a way that when, during rotation of the fluid conduits first mass portions of the first fluid and second mass portions of the second fluid are alternatingly transported by the first fluid conduit into or from the fluid separator, third mass portions of the first fluid and fourth mass portions of the second fluid are alternatingly transported from or to the fluid separator by the second fluid conduit. A ratio between each of the first mass portions and each of the second mass portions is substantially greater than a ratio between each of the third mass portions and each of the fourth mass portions. This provides for a net flow of one of the first and second fluids through the apparatus.

    摘要： A screw displacement pump (10) for comingled material has a body (11) defining a chamber (12'). Inlets are provided for the admission of fluid to the chamber and an outlet is provided for discharge of fluid from the chamber (12') intermeshing screw members (40) are mounted for rotation within the chamber (12') for transporting comingled material from the inlet to the outlet, the threads (41,42) of the intermeshing screw members (40) being of opposite hand. The pitch of the screws (40) at the outlet end thereof is smaller than the pitch of the screws (40) at the inlet end thereof to cause compression of gaseous material being transported. Clearance is provided between the screws (40) and between the screws (40) and the walls of the chamber (12') to allow sufficient leakage of the material towards the inlet, when the material is in the liquid phase, to avoid a liquid lock.

    摘要： A pump (10) for dispensing liquid from a reservoir (60) comprising: a piston-forming element (14) axially received in a piston chamber-forming member (12) and having a central axially extending hollow stem (38) with a central passageway (46) having an outlet (48) from which liquid is dispensed, at least one annular chamber (64,66) formed annularly about the stem (38) between the piston forming element (14) and the piston chamber-forming member (12) wherein said piston-forming element (14) has a bellows member (200) with a bellows chamber (186) open to the passageway (46), the bellows member (200) being collapsible to increase and decrease the volume of the bellows chamber (186) with reciprocal sliding of the piston-forming element (14) between a retracted position and an extended position to draw fluid through the outlet (48) and to expel fluid in the bellows chamber (186) out the outlet (48).

    摘要： A pump for pumping fluid including: a pump body (7) having a pumping chamber (14) therein; an inlet control means (23) adapted to be in fluid communication with a fluid supply means for supplying fluid to the pump; and an outlet control means (24) adapted to control the delivery of fluid from the pump; wherein when a fluid at least substantially consisting of gas or vapour is supplied to the pumping chamber (14) through the inlet control means (23), the fluid is pumped upstream from the inlet control means (23), and when a fluid at least substantially consisting of liquid is supplied to the pumping chamber (14) through the inlet control means (23), the fluid is at least substantially pumped through the outlet control means (24).
