摘要： A pipe connection structure according to one aspect of the invention is provided. The pipe connection structure includes a first pipe member and a second pipe member. A sealing portion of the first pipe member includes a first abutment surface in a tapered shape, a diameter of which is increased toward a tip of the first pipe member. An end of the second pipe member includes a second abutment surface in a tapered shape, a diameter of which is reduced toward a tip of the second pipe member. The second abutment surface is pressed and abuts against the first abutment surface. An abutment section of the second abutment surface and the first abutment surface is located on a radially inner side of an inner wall surface of the first pipe member.

摘要： A high-pressure fuel pump includes a pump housing, a pressurizing member, a suction valve seat, a suction valve body, and a suction valve chamber. The suction valve seat includes a first projected wall section that is projected to an upper side in a vertical direction. The pump housing includes a second projected wall section that is directed to the upper side in the vertical direction. A height of the lowest position in a portion of the second projected wall section that is projected to the upper side in the vertical direction is higher than a height of the lowest position in a portion of the first projected wall section that is projected to the upper side in the vertical direction. A first initial fuel pool is provided on an downstream side of the second projected wall section and on the upstream side of the suction valve seat.
