    摘要: Method for bending a plastic pipe including arranging a bending portion of a plastic pipe in a heating zone of a heater and performing contactless local heating of the bending portion, wherein the heater is adapted to provide a first predetermined temperature difference between a neutral zone of the bending portion and a compression zone of the bending portion and a second predetermined temperature difference between the neutral zone and the compression zone, of the bending area and an expansion zone of the bending area, introducing bending forces on holding regions arranged on the plastic pipe at a distance from the bending area and/or introducing bending forces on the bending area for deforming the plastic pipe into a deformation position and cooling the plastic pipe in the deformation position.

    摘要: A displacement pump with a pot-shaped housing, a rotor which is swivel-mounted about a rotation axis inside the housing, and two blades which are guided in a movable manner insider the rotor, wherein the pot-shaped housing includes an inner peripheral wall which has a sealing portion for tightly adjoining the rotor and a chamber portion for tightly adjoining the blade tips, as well as for dividing the internal space of the housing into chambers. The rotor has two blade receptacles for receiving and guiding the blades, wherein each internal radially extending blade tip restricts a pressure chamber in the respective blade receptacle. Both pressure chambers are fluid-connected to one another via a connection element, wherein the total volume of both pressure chambers and the connection element remains at the same level during a rotation of the rotor, at least while the blade tips are attached to the chamber portion.
