When the valve-opening pressure of a relief valve is increased in order to accommodate a higher fuel pressure, a larger relief valve is installed, so the size of a high-pressure fuel supply pump increases. In the present invention the relief valve is installed inside a discharge joint. Thus, by effectively utilizing excess space in the interior of the pump, and without significantly increasing the size of the pump itself, it is possible to obtain a high-pressure fuel supply pump that exhibits sufficient relief capability even at a higher fuel pressure.

Fixation of a yoke (second yoke) serving as a component to constitute an electromagnetic circuit is achieved when an annular member is inserted into a groove of a magnetic core. However, a gap is necessarily formed between the yoke (second yoke) and the annular member in terms of variations in the dimensions of respective components, and sound comes out when the yoke and the annular member contact each other. Further, when the annular member is fit into the groove from an axial direction, a load becomes excessive since interference is increased at an insertion start point to fit the annular member into the groove. Further, when the annular member is fit into the groove from a radial direction, the fitting is not allowed since a yoke outer diameter interferes with the annular member. Therefore, the present invention provides an electromagnetic valve mechanism provided with: a fixation core 39 that has a large-diameter part 39-S1 and a small-diameter part 39-S2 and attracts a movable core ...

The objective of the present invention is to provide a fuel supply pump which both prevents cavitation erosion of a relief valve seat portion during high pressurization and reduces a maximum pressure when an abnormally high pressure is released. To this end, the fuel supply pump is provided with a relief valve mechanism including a seat portion and a relief valve seated on the seat portion, and is set such that a discharge pressure is at least equal to 30 MPa, wherein a seat angle of the seat portion is formed in such a way as to be 40° to 50°, and the valve opening pressure of the relief valve mechanism is set to be at least 2 MPa greater than the set discharge pressure.

The purpose of the present invention is to detect a defect that is present above or under an interface of two members in a laser welding portion of a lap joint. To achieve this, a transverse wave generation laser (LaTT) and a longitudinal wave generation laser (LaTL) are irradiated to different locations of one side of a welding line (We). A transverse wave reception laser (LaRT) and a longitudinal wave reception laser (LaRL) are irradiated to different locations of another side of the welding line (We). A defect (De1) at a location that is deeper than an interface (SB) between a first member (201) and a second member (202) is detected by detecting a transverse ultrasonic wave (WT) with the transverse wave reception laser (LaRT). A defect (De3) at a location that is shallower than the interface (SB) is detected by detecting a longitudinal ultrasonic wave (WL) with the longitudinal wave reception laser (LaRL).

The purpose of the present invention is to provide a high-pressure fuel supply pump capable of holding a spring holding member while allowing the height of the pump body to be reduced. The high-pressure fuel supply pump is provided with: a pump body forming a pressurization chamber therein by an inner wall section; and a flange section for fixing the pump body to a high-pressure fuel supply pump attachment section. The pump has: a cylinder inserted into a hole part of the pump body from below such that the pressurization chamber is formed further above the uppermost surface of the cylinder; and a spring holding member having an outer peripheral section press-fitted to the pump body and a holding section holding a spring part for biasing the pump body between the outer peripheral section and the inner peripheral section. The spring-side lowermost end part of the holding surface of the spring holding member is disposed above the lowermost end part of the flange section.

Provided is a high pressure fuel pump such that the film of fuel on the sliding parts is not worn through, even when there is no need to pressurise fuel. The high pressure fuel pump is provided with two low pressure fuel openings, apart from a high pressure fuel outlet to a high pressure fuel accumulator. One of the two low pressure fuel openings connects to a low pressure fuel accumulator and the other connects to a low pressure fuel pump. Thus, even in a mode where only the low pressure fuel injection valves inject fuel and the high pressure injection valves do not, because the interior of the high pressure fuel pump is continually filled with fresh fuel, the plunger and cylinder can be protected against rises in temperature and protected from seizing up.
