摘要： In a fuel injection device, a control body has a pressure control chamber, an inflow port and an outflow port. The inflow port and the outflow port are opened at an abutting surface exposed to the pressure control chamber. In the pressure control chamber is arranged a floating plate for pressing the abutting surface by a pressing surface with the pressure of the fuel to interrupt communication between the inflow port and the pressure control chamber. The abutting surface of the control body is provided with an outer opposite surface portion opposite to an outer edge of the pressing surface in a displacement axis direction of the floating plate, and the outer opposite surface portion has a special depressed portion that is depressed in the displacement axis direction and that extends along the shape of the outer edge of the pressing surface.

摘要： In a fuel injection device, a pressure control valve is configured to make communication between an outflow port and a return channel and to interrupt the communication so as to control pressure of a fuel in a pressure control chamber, a valve member is configured to open and close a valve portion in response to the pressure of the fuel in the pressure control chamber, and a pressing member is arranged to be reciprocated and displaced in the pressure control chamber. The pressing member has an outer wall surface portion that is opposite to an inner wall surface portion of the control body to be capable of contacting the inner wall surface portion of the control body, and at least one of the outer wall surface portion of the pressing member and the inner wall surface portion of the control body is provided with a recess portion that is recessed to a side separated from the other one of the outer wall surface portion of the pressing member and the inner wall surface portion of the control body.
