Title: Fuel injection device
Inventor: HATA YASUAKI
IPC: F02M51/06
Filed: 1982-03-11
Abstract: PURPOSE:To eliminate a delay in fuel injection and as well to enable the amount of fuel injection to be precisely controlled, by forming, in the vicinity of the jet port of  a fuel injection device, a fuel chamber having a volume capable of accumulating an  amount of fuel larger than the maximum injection amount in one cycle. CONSTITUTION:Under such a condition that a fuel jet port 16 is blocked by pressing a  needle valve 21 by a coil spring 20 so that the needle valve 21 is pressed against a  valve seat 15, a movable iron core 18 is pulled up overcoming the force of the coil  spring 20, by enerziging an electromagnetic winding 12 for magnetically energizing a  stationary iron core 11, and therefore, the needle valve 21 is moved upward, simultaneously. Further, when the abutting of the front end oblique surface 22a of the needle  valve 21 against the associated oblique surface 22b of the jet port 16 is released, fuel in  a fuel chamber 25 is injected from the jet port 16 through a gap between both oblique  surfaces 22a, 22b. With this arrangement, since the fuel chamber 25 is formed in the  vicinity of the jet port 16, that is, at a short distance from the jet port 16, corresponding to the length of the oblique surface 22a or 22b, fuel is injected from the jet port 16  in a moment when both oblique surfaces 22a, 22b are separated from each other.

CONSTITUTION:Well regions 22 and 23 whose impurity concentration is lower than that of diffused layers having the low impurity concentration are provided in the low-impurity-concentration diffused layers in a resistor region 6 in a resistor and in the offset region 14 in a MOS type transistor so as to surround high-impurity-concentration diffused layers in a resistor contact region 7 in the resistor and in a drain region 13 in the MOS transistor. The intersecting regions of the diffused layers of the low impurity concentration and the diffused layers of the high impurity concentration are located in the well regions 22 and 23. When the gradient of the impurity concentration is made gentle, the concentration of an electric field in this region can be alleviated. In this way, the dependency on the impurity concentration can be made less, and high breakdown strength can be obtained.
