PUMPING DEVICE AND TRANSPORTING DEVICE FOR IT Russian patent published in 2022 - IPC F04B43/00 F04B43/02 F04B43/12 

FIELD: oil industry.

SUBSTANCE: group of inventions relates to a pumping device and a transporting device for it. The device has at least one drive unit (12) and at least one transporting device (14) in the form of membrane, including at least one at least ring-shaped main part (16), and has at least one transporting surface (18), which is located on discharge side (20) of part (16), which has at least one activating element (22) for connection to at least one driving element (24) of unit (12), which is located on activating side (26) of part (16). Element (22) interacts with element (24). The direction facing away from side (26) extends at least perpendicular to the axis of rotation of element (24) of unit (12). Element (22) has the maximum longitudinal length, which is less than the maximum longitudinal length of part (16). Side (26) has a surface shape in the cross section of device (14) that differs from a rectilinear shape, which at least corresponds to a shape of surface (18) in at least its transport-free state.

EFFECT: group of inventions is aimed at creating a vacuum for transporting the working medium by means of the pumping device.
