Abstract :
The equation describing liquid pressure located between armature and core during their attraction is written for
the membrane magneto hydraulic pusher discussed in the work. Resulting from solution of the boundary problem set for
the mentioned equation there is obtained the time distribution of pressure in liquid. Through integration of the pressure
value on the pusher’s electromagnet core ring a magnitude of a displacement resistance force for an oil to be squeezed is
determined, based on which the ratio between time and armature stroke is obtained. An opinion is expressed on the
reasonability of reduction of electromagnet armature ring-shaped end area with the purpose of armature attraction time
reduction that may be implemented, if the armature end surface will have a narrow ring-shaped projection. The conclusion
on the optimal time of armature attraction is drawn.
