摘要： In a fuel injection device, a pressing surface of a pressing member presses an opening wall surface to interrupt communication between an inflow port and a pressure control chamber when communication between an outflow port and a return channel is made by a pressure control valve, and the pressing surface of the pressing member is displaced and separated from the opening wall surface to open the inflow port of the opening wall surface to the pressure control chamber when the communication between the outflow port and the return channel is interrupted by the pressure control valve. One of the pressing surface of the pressing member and the opening wall surface of the control body is provided with an inflow depressed portion and an outflow depressed portion partitioned from each other, and a depressed dimension of the inflow depressed portion is larger than a depressed dimension of the outflow depressed portion.

摘要： A fuel injection device includes a cylinder that defines a pressure chamber at an end portion of a nozzle needle. A floating plate as a control member is placed in the cylinder. A cutout portion and multiple grooves are formed in the floating plate. The cutout portion and the grooves causes a gap between a large-diameter inner circumferential surface and an outer circumferential surface to communicate with the pressure chamber. The cutout portion and the grooves reduce a contact surface portion between the cylinder and the floating plate and divide the contact surface portion into multiple island portions. As a result, it is possible to reduce the contact surface portion.

摘要： A fuel injection device has therein a recovery channel provided in a first valve body, and a fuel channel provided in the first valve body and a second valve body. The fuel channel is opened by openings at a first end surface of the first valve body and a second end surface of the second valve body. One of the first end surface and the second end surface is provided with an end surface groove connected to the recovery channel. In the fuel injection device, the end surface groove is provided to enclose at least a part of the opening and is separated from the opening by a clearance, and one of the first valve body and the second valve body has a side surface groove extending in a circumferential direction at an outer periphery of the one of the first valve body and the second valve body.

摘要： PROBLEM TO BE SOLVED: To reduce wear of a sliding part by absorbing axial deviation and deflection deformation between two members in a back pressure control valve consisting of the two members of a long column-like control piston 15 and a needle 43. SOLUTION: A fuel injection valve 1 includes a nozzle body 40 for slidably supporting the needle 43 for opening an injection hole 49, a valve body 20 having an end surface exposed to a pressure control chamber 61 separated by a sleeve 14 where a fuel pressure is controlled and having a control piston 15 penetrating through a fuel chamber 42 filled with a high-pressure fuel and an opening and closing valve mechanism 5 for releasing the fuel pressure of a pressure control chamber 61. An end side of the control piston 15 and another end side of the needle 43 are integrally held in an axial core direction by a connection mechanism via a shim 77 for allowing axial deviation in a direction perpendicular to the axial core direction and deflection deformation along the axial core direction 7.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection device with a pressing member attaining high responsiveness to a pressure control valve and surely intercepting fuel. SOLUTION: A control body 40 includes a pressure control chamber 53, an inflow port 52a letting fuel flow into the control chamber 53, and an outflow port 54a letting the fuel flow out of the control chamber 53. The inflow port 52a and the outflow port 54a are opened in an opening wall face 90 exposed in the pressure control chamber 53. In the pressure control chamber 53, a floating plate 70 is arranged for disconnecting the inflow port 52a and the pressure control chamber 53 by pressing the opening wall face 90 with fuel pressure. The floating plate 70 is formed with an outflow recess 97 and an abutting projection 98 on a pressing face 73. When the opening wall face 90 is pressed by the pressing face 73, the abutting projection 98 also abuts against the opening wall face 90 in the outflow recess 97 to inhibit deformation of the floating plate 70.
