When the tool locus exceeds the stored stroke limit (S5), the drawing is stopped and a message is displayed (S8).
When the second housing (1) has reached a stroke limit position with respect to the first housing (8), the magnetic field generation means and a vibrator repel each other.
The current is then cut off and the plunger returns by spring action toward the gap, whereafter the current is reapplied to the coil to attract the other head of the plunger by reluctance action to drive the plunger to its other limit of travel.
And, setting restrictive rod (11) and tad (13) of avoiding overflow on the jaws (1), that makes the tissue intake completely and shapes the pouch successfully.
The device is configured to allow the bottom face of the upper housing to slide with respect to the top face of the lower housing until a limit of travel is reached.
The control piston (130) of the fuel injection valve (2) has a land (124) at its top end which together with the underside (120) of a control body (132), forms the stroke limit of the control piston (130).
The single electrical coil is coupled to the core and is provided with electrical current to attract one of the heads toward the core by reluctance action to drive the plunger to a limit of travel in one direction.
