Abstract:
A dispenser body having a liquid inlet, a discharge outlet, and a flow channel capable of directing a flow of the hot melt adhesive from the liquid inlet to the discharge outlet. The flow channel includes a valve seat between the liquid inlet and the discharge outlet. The dispensing module further includes a needle having a valve member mounted for movement in the dispenser body between an open position in which the valve member is disengaged with the valve seat allowing liquid flow from the discharge outlet and a closed position in which the valve member is engaged with the valve seat preventing liquid flow from the discharge outlet. A first electromagnetic coil is activated to move the needle to the open position and a second electromagnetic coil is activated to move the needle to the closed position.
