PUMP UNIT WITH ELECTRIC DRIVE Russian patent published in 2016 - IPC F04B17/03 

FIELD: pumps.

SUBSTANCE: invention relates to devices for pumping fluid media and can be used in industry, on transport and in everyday life in pumping liquids, other incompressible and compressible fluids, as well as in oil production from wells. Pump unit consists of a housing, electrically driven armature located in housing, a displacer, located in front part of housing. Electrically driven armature and displacer are connected. Electrically driven armature consists of series-connected rear electrically driven spacer unit, electrically driven movement unit, configured for displacement relative to housing in direction of change of its length, and front electrically driven spacer unit. In contrast to nearest analogue at least one electrically driven spacer unit is a magnetostrictive spacer unit and/or electrically driven movement unit is a magnetostrictive movement unit. Task of invention consists in widening range of existing equipment.

EFFECT: technical result achieved by implementing present invention is realisation of said purpose.
