Small lifting time of pusher’s rod used as a drive gear in vehicles and machinery is one of the key factors of their reliable operation, and increasing the productivity and durability. In its turn, the push rod lifting time depends on both electromagnetic characteristics of pusher’s electromagnet and on those mechanical or hydraulic resistances that are predetermined by design features of the pusher. One of the reasons of push rod lifting time increment is the resisting force of work fluid extrusion situated between the armature-piston and the electromagnet core. In order to make the magneto hydraulic pusher design even more perfect it is desirable to determine armature-piston attraction time taking hydraulic resistance into account. In the work there is established time distribution of pressure in work fluid area, is calculated the work fluid resistance when armature-piston attracts to the core and there is determined attraction time with consideration to hydraulic resistance.
