Pumping procedure

摘要

The displacement component of the pump has a jacket with an elastically variable surface and is squeezed through a reversible drive. The displacement component is fixed on the side which faces away from the drive, and may be square, cylindrical, ball-shaped or similar, and may have an end face which is rotatable and reversible around an axis which passes through the end face. The displacement component may be provided with two end faces, and the jacket can be supported by movable rods. The energy for driving of displacement component may be in the form of an electric current from a cable connector.
