MOTOR POPPET VALVE AND AN EGR DEVICE FOR AN INTERNAL COMBUSTION ENGINE USING THE SAME

Motor control means of a motor poppet valve has initial motor torque setting means for setting the initial motor torque of an electric motor so that the initial motor torque equals a torque corresponding to a force biasing a valve element of a poppet-valve body toward a valve seat or a proximate val...

Beschreibung
Zusammenfassung:	Motor control means of a motor poppet valve has initial motor torque setting means for setting the initial motor torque of an electric motor so that the initial motor torque equals a torque corresponding to a force biasing a valve element of a poppet-valve body toward a valve seat or a proximate value, and drives the electric motor so as to obtain the initial motor torque when driving the electric motor to detach the valve element from the valve seat.
