Title: Fuel injection valve
Inventor: TAKIGAWA MASAHIRO
IPC: F02M57/02
Filed: 1984-06-05
Abstract: PURPOSE:To make such a valve as having secured sealability in a valve seat with the valve and being excellent in high-speed responsiveness attainable, by letting the plate valve touch or separate to or from a valve body according to pressure of fuel inside a pump chamber. CONSTITUTION:When the positive voltage is impressed on an electrostrictive element 1, displacement is produced in an axial direction, overcoming reaction force of a plate spring 10 whereby depressing a piston 7 and making pressure inside a pump chamber 2 go up, so that this pressure becomes more than the valve opening pressure decided on both magnetic and spring forces of a plate valve 4, thus fuel injection gets started. Then, fuel depresses a circumferential end part of the plate valve 4, while the discharged fuel collides with a spray angle correcting part 3b, therefore it comes to be spouted toward a lower part in consequence. Injection automatically stops if pressure inside the pump chamber 2 drops down to some extent. Afterward, if voltage in the electrostrictive element 1 is removed or the negative voltage is impressed, the electrostrictive element 1 contracts in the axial direction.

Filed: 1985-05-31
Abstract: PURPOSE:To correct automatically the variation in a time constant circuit of an active filter by impressing a reference voltage fed to a variable capacitor to a CR oscillator together with a control voltage to a variable capacitor of the active filter. CONSTITUTION:A signal from a reference oscillator 1 is inputted to an input terminal of a phase comparator 2 and an output of an CR oscillator 4 whose oscillating frequency depends on a product between a capacitor C using a variable capacitor and a resistor R is inputted to the other input. Then the comparator 2 compares the phase of two signals and the control voltage VC is applied to one terminal of a variable capacitor so as to cause the oscillator 4 to oscillate an oscillation frequency equal to a reference frequency of the reference oscillator 1. The reference voltage Vr is fixed to the other terminal of the variable capacitor to form a PLL 5 and the product CR is made constant independently of the variation in components. In floating the reference poatential side of the variable capacitor of the active filter 6, the reference voltage Vr of the oscillator 4 is given to the variable capacitor of the filter 6 as a reference potential thereby correcting the variation in the components accurately.
