摘要： PROBLEM TO BE SOLVED: To allow a vehicle to travel safely by operating a throttle valve to open/close mechanically between total closure and set maximum opening at the occurrence of abnormality or failure in an electronic control system. SOLUTION: An electronic control system electronically opens/closes the throttle valve 4 by transmitting free rotation to a throttle valve stem 3 of an actuator lever 16 driven by an actuator 9, through a throttle valve stem lever 17 rotated integrally with the throttle valve stem 3 and movable in an axial direction. At the occurrence of abnormality or failure in the electronic control system, an auxiliary actuator 25 is operated to move a linear moving output shaft 29. The throttle valve stem lever 17 is thereby moved in the axial direction and separated from the actuator lever 16. The throttle valve 4 is closed by a throttle valve return spring 6 and then rotated from the closed position by the engagement of a cam face 30A of a lever guide 30 with an operating lever 8 stuck to the throttle valve stem 3. The throttle valve 4 is thereby operated to open/close mechanically according to the stroke of the linear moving output shaft 29. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent uncomfortable feeling from being given by suppressing or eliminating loud noise when a pressure-reducing valve of a pressure regulator with compressed fuel taken as gaseous fuel of constant positive pressure has a small opening. SOLUTION: A partition member 21 having a through hole 23 for flowing compressed fuel into the pressure-reducing valve 11 is fitted into an inlet chamber 3 to change the natural frequency of the inlet chamber 3 to a different value. This prevents vibration generated when a valve body 12 has a small stroke and loud noise due to resonance frequency between the valve body 12 and a valve lever 10, which resonates with the inlet chamber 3.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve having excellent responsiveness and capable of accurately and stably performing opening/closing operations for a long period. SOLUTION: In this fuel injection valve, a movable iron core 23 and a valve element 24 are fixed to a plate spring-made return spring 17, and reciprocatingly moved in a floated state. A nonmagnetic cylindrical contact member 26 to bring the compression of a cushioning layer 25 installed at the tip face of a fixed iron core 10 into an elastic deformation range is installed on the tip outer peripheral surface thereof. The contact member 26 is closely fitted to a fitting hole 28 using, as a center, the centerline N-N of the fixed iron core 10 fitted to a nonmagnetic holding member 27 to position the fixed iron core 10 and the movable iron core 23 on the centerline N-N. Since the cushioning layer 25 and the contact member 26 make constant the suction stroke of the movable iron core 23 and stabilizes the valve opening amount of the valve element 24. Thus, the responsiveness can be improved by securing a release voltage. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To supply exactly an engine-requiring flow rate at a low temperature upon supplying liquefied gas after vaporization and decompression. SOLUTION: A liquid phase L and a gas phase G of a cylinder 1 are connected to a regulator 17 for keeping the liquefied gas at a positive pressure. The regulator 17 selectively introduces the gas phase when it is lower than a predetermined temperature, and the liquid phase when it is higher than the predetermined temperature. If the engine-requiring flow rate is larger than a gas phase generation amount of the cylinder 1 even when it is lower than the predetermined temperature, the liquid phase is heated and vaporized by a heater 6 to be introduced in the regulator 1. Therefore, excess fuel is prevented by the use of the gas phase, and lack of the fuel is resolved by the use of the liquid phase in combination. COPYRIGHT: (C)2005,JPO&NCIPI
