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: An eccentric screw pump for delivering solid-laden liquids includes a rotor and a stator within which the rotor is rotatably arranged. The rotor and stator are arranged and designed with respect to one another in such a way that at least one chamber is formed, which serves to transport the liquid. The eccentric screw pump has a drive motor for rotating the rotor, a control device for controlling the drive motor at least in a working state, in which the rotor is rotated, and an idle state, in which the rotor does not rotate, and an engagement unit, which is designed to set an engagement between the rotor and stator to an idle engagement in the idle state and to a working engagement in the working state. The idle engagement is less than the working engagement. A method for operating the eccentric screw pump is also disclosed.

Abstract: Various examples are provided for progressive cavity pumps and motors. In one example, among others, a progressive cavity pump (or motor) includes a stator having a hyperboloidal internal bore including a plurality of spiral lobes, and a rotor comprising a plurality of spiral lobes positioned within the hyperboloidal internal bore of the stator. A longitudinal axis of the rotor is non-planar, non-parallel, and non-intersecting with a longitudinal axis of the stator. The stator can include an elastomeric material coating the hyperboloidal internal bore of the stator, which can reduce the effect of friction and abrasion during operation. The elastomeric material can include fluoro-based elastomers, other elastomeric materials or combinations thereof. For example, a fluoromonomer such as tetrafluoroethylene (TFE) or a fluoropolymer such as polytetrafluoroethylene (PTFE) can be used. The rotor can be configured to allow for displacement to adjust an interference fit between the rotor and the stator.

Abstract: A fluid pump (10) or motor (100) includes a pair of enmeshed tapered rotors (22,24,122,124) having intersecting axes of rotation. The first rotor (22,122) includes a small low pressure end (34,54,134,154) and a larger high pressure end (32,52,132,152) and a spiral thread (36,56,136,156) that increases in width and depth as it progresses from the high pressure end (28,128) to the low pressure end (26,126). The second rotor (24,124) enmeshes with the first rotor (22,122), and has an identical structure, except that its threads (36,56,136,156) progress in the opposite direction. Both rotors (22,24,122,124) are mounted on sliding splines (42,62,142,162) which permit them to move, to a limited extent, into and out of their respective receiving cavities. The pressure on the high side (28,128) of the pump (10) or motor (100) tends to urge the rotors (22,122,24,124) against the walls (16,20,116,120) of the receiving cavities thereby improving their sealing capabilities and the overall efficiency of the pump (10) or motor (100) as a whole.

Abstract: A blending pump assembly for accurately maintaining the proper ratio of two fluid components. Flow of a first fluid is utilized to drive a fluid motor, which in turn drives a pumping mechanism to inject a proportional amount of a second fluid into the flow of the first fluid. The fluid motor and pump are sized so that a predetermined ratio between the two fluids is maintained regardless of changes in pressure and flow rate of such first fluid.
