Title:
INJECTION SWITCH TIMING DETECTING DEVICE FOR MULTIKIND FLUID INJECTION VALVE
Document Type and Number:
Japanese Patent JP2610369
Kind Code:
B2
Abstract:
PURPOSE: To detect timing of switching injection fluid, in the case of injecting two kinds of the fluid in the same injection stroke.
CONSTITUTION: A slidable needle valve 2 of sliding in a direction of opening an injection hole 1 by a supply pressure of the first fluid while opening/closing the injection hole 1 formed in a nozzle main unit 3, flow path 61 formed in the interior of the needle valve 2 and also guiding the first fluid to the injection hole 1, slidable stop valve 62 of sliding in a direction of closing the flow path 61 by a supply pressure of the second fluid and the second fluid supply flow paths 6, 7 for guiding the second fluid to the injection hole 1 are provided. A sensor bar 77 slide integrally with this stop valve 62 while connecting the one end to the stop valve 62 is provided to provide a sensor 74 for detecting sliding action of the sensor bar 77, opposite to the other end of the sensor bar 77.
