IPC: F02M25/07
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To prevent a fluid leakage from between a valve and a valve seat in a double poppet type valve device. SOLUTION: In the whole operation region of an engine, the conditions for increasing an elongation amount of a valve shaft 11 to the maximum extent are that a temperature of exhaust gas is high and a flow rate of exhaust gas is high in an EGR region. When operation plunges into the outside of EGR region where load is high from the EGR region, for example, operation is accelerated from the EGR region, there are possibilities that both of two valves are not seated on valve seats together, EGR gas leaks from a clearance between the valve on one side and the valve seat on one side, and output performance is worsened and a PM amount increases due to the mixture of EGR gas into suctioned air.  In this case, a difference ΔL between a dimension L1 between the valve seats 14 and 15 and a dimension L2 between the valves 12 and 13 (ΔL=L1-L2)[L1>L2] when the valves are fully closed at normal temperature is set to 0.15 mm, and a clearance C of 0.15 mm is provided between the valve 12 on upper side (the valve positioned on a rear side in the direction of opening valve) and the valve seat on upper side (the valve seat positioned on a rear side in the direction of opening valve) at normal temperature.

IPC: H02K23/40
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To reduce cogging torque, suppress noise and vibration, and reduce loss torque by specifying the number of poles of a rotor iron core with a coil wound around, and the number of poles of a magnet formed so as to face the rotor iron core respectively, and subjecting the rotor iron core to skew. SOLUTION: A magnet 5 which is formed so as to face opposite a rotor iron core 2 with a coil wound around is fixed in a case 10 with 4 poles of N-pole and S-pole polarized alternately in a circumferential direction. The rotor core 2 with three magnetic poles is disposed at a position facing opposite the magnet 5 with a gap put between them so as to be freely rotatable, and a skew forming part 4 which inclines at a fixed angle θ is applied in the axial direction of the rotor iron core 2. When the number of the poles of the rotor iron core 2 is 3n, and the number of the poles of the magnet is 4n (where (n) is an integer of one or more), by subjecting the rotor iron core 2 to skew, it is possible to reduce cogging torque with attraction and repulsion accompanying between the poles of the rotor iron core 2 and the poles of the magnet 5.  Consequently, noise and vibration are restrained, making obtaining smooth motor rotation possible.
