    Abstract: Compression of water vapour as R718 is disclosed with and without addition of additives as an aqueous solution in rotational displacement machines, i.e. refrigeration, air-conditioning and heat pump technology. To largely avoid over or under-compression, it is proposed for the easiest possible adaptation of the currently effective internal volume ratio as so-called iV value in the displacer that the compressor housing starting from the outlet side with rotor profile length LR over a length LiV comprises planar, i.e. flat iV disks (3j) with the index j for 1≤j≤n; n is the number of disks; n≥1 with a width bj per iV disk having planar surfaces PF preferably perpendicular to the neutral axis AN. The iV disks are displaced in a targeted manner individually by movement control devices (5j) per iV disk in each case by a distance si where 0

    Abstract: A liquid ring pump is provided. The liquid ring pump is designed to reduce the overall envelop of the ring pump. The liquid ring pump includes a housing and an impeller. The housing defines an impeller cavity. The impeller cavity has an inlet port and a discharge port. The impeller is positioned within the impeller cavity for rotation about a central rotational axis. The impeller includes a central hub defining a conical outer surface and a plurality of angularly spaced apart main vanes extending radially outward from the conical outer surface relative to the central rotational axis. The inlet and discharge ports may be located on a same side of the impeller housing.

    Abstract: A screw compressor or pump includes: a housing, two intermeshing rotors respectively rotatably mounted in the housing by two shafts; each rotor having a helix tooth spirally formed on the rotor lengthwise, with the helix tooth gradually decreasing an outer diameter of a top land surface of the helix tooth corresponding to a gradually contracted rotor chamber, and having a spiral groove juxtapositioned to the helix tooth and spirally formed in the rotor lengthwise; the spiral groove having a groove bottom surface extrapolatively defining an inner cone tapered towards a suction port side; the rotor chamber having a conical wall surface extrapolatively defining an outer cone tapered towards a discharge port side, thereby forming a gradationally contracted cavity between the spiral groove and the conical wall surface of the rotor chamber as confined between the inner and outer cones for increasing the compression or pumping efficiency.
