摘要： PURPOSE:To perform interval adjustment between pilot injection and main injection in an easy manner, by installing an on-off control mechanism in an interconnecting passage between a pressure chamber of a fuel injection pump and a hydraulic chamber of a fuel control valve. CONSTITUTION:An interconnecting passage 814 is installed in an interval between a pressure chamber 131 of a fuel injection pump 1 and a hydraulic chamber 815 of a fuel control valve 8. A valve body 812 of the fuel control valve 8 is inserted into this interconnecting passage 814, and driven by a solenoid valve 81. The timing of opening and closing the valve body 812 is controlled and an interval between pilot injection and main injection is adjusted. With this constitution, adjustment for both pilot and main injection intervals is easily performable.

摘要： PURPOSE:To eliminate an ignition coil and a distributor, by a method wherein a piezo-electric element is incorporated in an ignition device, and spark discharge is produced by exerting a fuel pressure fed to an injection nozzle. CONSTITUTION:The fuel fed from an injection pump is fed to an injection nozzle through an injection pipe and is injected into a combustion chamber. When a fuel pressure is boosted, a force is exerted on the under surface of a piston 215 which is moved upward against a spring 216, and fuel admits through a gap between a center part 202d and the under surface of the piston 215 to rapidly push upward the piston. In this case, a rodform member 213 is rapidly pulled up against the elastic force of a coned disc spring 214, and thereby a compression force, applied on a piezo-electric element 206, is released, a voltage is induced resulting from deformation due to restoration, and discharge is produced in a spark gap G. Thus, an ignition coil and a distributor are eliminated.

摘要： PURPOSE:To perform supply and stop of a high pressure fuel with minor force in good response by furnishing the arrangement with a No.1 oil pressure chamber, No.2 oil pressure chamber, oil-hydraulic opening/closing valve, electrical opening/closing valve, etc. CONSTITUTION:As both a solenoid valve 51 and a needle valve 52 are closed before operation, No.1 oil pressure chamber 524 is out of communication with a drain port 502, and an output port 528 is shut. If current is supplied to a solenoid valve 511 at the starting time of injection, the valve element 512 will rise to cause communication between No.1 oil pressure chamber 524 and drain port 502, so that the fuel in No.1 oil pressure chamber 524 be relieved. Because a needle valve 522 is equipped with a throttle 527, the pressure in No.2 oil pressure chamber 525 increases much higher than that in No.1 oil pressure chamber 524 following said relief of the fuel from No.1 oil pressure chamber 524, so that the needle 522 shifts upward. Then the output port 528 is opened, and the fuel is sprayed out of this port to serve as an injection nozzle.
摘要翻译：目的：通过配备1号油压室，2号油压室，油压开闭阀，电开/关闭，以较小的力量供应和停止高压燃油。阀等。构成：由于电磁阀51和针阀52在运转前关闭，所以1号油压室524与排水口502不连通，输出口528关闭。如果在注入开始时向电磁阀511供给电流，则阀元件512将上升，从而引起第一油压室524与排出口502之间的连通，使得第一油压室524 放心由于针阀522配备有节流阀527，所以在从第一油压室524排出燃料后，在第二油压室525内的压力比第一油压室524的压力高得多，使得针522向上移动。然后输出口528打开，燃料从该口喷出，用作喷嘴。

CONSTITUTION:To constitute a piezoelectric motor, a rotor 2 supported by an output rotating shaft 3 is provided within a housing 7 and a piezoelectric plate 1 is arranged above said rotor so that its tip 11 touches the top face of the rotor 2. Further, this piezoelectric plate l is inclined at an angle theta and urged on the outer peripheral face of the rotor 2 by means of a biasing plate 4, a bolt 5 and a coiled spring 6 via felt 4. In this case, the piezoelectric plate 1 is made gradually smaller in the width of its tip and a circular cavity 13 is provided in the plate. Moreover, a conducting electrode is formed all over both faces of the piezoelectric plate l so that an AC power is appled thereto. Thus, a guantity of expansion deformation of said plate 1 becomes large by provision of the cavity 13 so as to increase the rotational speed and torque of motor output substantially.

摘要： PURPOSE:To perform an exact initiation and completion of a fuel injection and an accurate control of a fuel injection rate by opening or closing a fluid passage through the movement of a valve body caused by charging an electric charge in capacitor means or discharging from the capacitor means to an electrostrictive element. CONSTITUTION:Drive means 25' shrink an electrostrictive element 14 by discharging an electric charge produced in the electrostrictive element 14 by means of first switching means 250 at a given time, moving a valve body 19 to an opening position. Also, the drive means 25' move an electric charge produced in the electrostrictive element 14 through second switching means 246 and 247 at another given time, shrinking the electrostrictive element 14 to move the valve body to the opening position. Further, the electric charge stored in capacitor means 248 and supplied to the electrostrictive element 14 at a given time stretches the element 14 to move the valve body to a closing position. Thus, an exact initiation and completion of a fuel injection and an accurate control of a fuel injection rate are enabled.

CONSTITUTION:A fuel injection valve, when it opens a valve body 146 by attracting a plunger 144 upward by electrification of a solenoid 108 simultaneously pressing a steel ball 148 to a valve seat 152 by a spring 168, connects a pressure chamber 134 in a power cylinder 128 to a drain passage 162, balancing the force acting on both end surfaces of a piston 132. Here the fuel injection valve, opening a needle valve 126 because the superhigh pressure of fuel acts in a pressure chamber 120 of an injection nozzle 114, injects fuel from a jet 124. In this case, throttles 191, 192 are respectively provided in a section 136A in the upstream side of a control fuel passage 136 and a drain passage 162. And the fuel injection valve, in which an opening area of the throttle 191 is formed larger than that of the throttle 192, attains the desired end.
