Title: Valve opening pressure switching device for fuel injection valve
Inventor: KAKIUCHI SUMIAKI
IPC: F02M47/04
Filed: 1986-02-13
Abstract: PURPOSE:To improve combustion characteristics by furnishing a pressure sensor to sense the pressure in a fuel injection pipe, changing over the valve opening pressure in accordance with the pressure sensed by this sensor, and thereby ensuring high pressure injection over the whole range of allowable loads. CONSTITUTION:In this fuel injection valve equipped with a valve opening pressure changeover device, a pressure sensor is provided to detect the pressure in a fuel injection pipe, and the valve opening pressure changeover device is controlled in accordance with the pressure in fuel injection pipe which is directly detected by this pressure sensor. This allows use of high pressure from the valve opening pressure changeover device over the whole range of allowable loads, much wider than the available range of any conventional device in which the number of engine revolutions is detected to serve for control of changing over the valve opening pressure, and thereby the combustion characteristic is improved greatly. Changing over the valve opening pressure may also be controlled by using the abovementioned pressure in the pipe and the lift of the valve for the upper and lower limits, respectively.

Abstract: PURPOSE:To reduce the weight, the size and the thickness of an optical head device. CONSTITUTION:A light splitter 41 has a splitting surface which consists of a diffraction grating 44 having first and second frame gratings having grating patterns different from each other formed on it.
