Abstract

PURPOSE: To make it possible to detect easily injection timeing only by replacing a few components by providing an injection valve body with nipple metal fittings in a fixed shape and a pressure sensitive element.
CONSTITUTION: At the tip of injection valve boky 1, nozzle chip 2 is provided, and fuel leaking in injection flows from the circumference of the valve body into airtight chamber 3 of injection valve body 1 and returns to a fuel filter, etc., from its top terminal through reflux pipe 4. Nipple metal fitting 7 has pressure conduction hole 9 open to airtight chamber 3 and is provided with pressure sensitive element 10 which detects leakage fuel pressure at its top terminal. Through hole in nipple metal fitting 7 is made thin enough to functiok as a throttle. When supplying fuel from an injection pump pushes up the valve body of nozzle chip 2, fuel in airtight chamber 3 is pushed out to flow passage 6 through hole 8 at the same time as leakage of fuel, but the pressure of guiding hole 9 is increased through the throttling of through hole 8, so that injection timing can be detected in the pressure variation of the fuel.
