摘要： A damper device is provided in a flow passage of a fluid. The damper device includes a plurality of diaphragm dampers that are stacked together. Each of the plurality of diaphragm dampers includes a first flexible portion, a second flexible portion, and a rim including a welded portion. A peripheral edge of the first flexible portion and a peripheral edge of the second flexible portion are welded together in the welded portion. Each of the plurality of diaphragm dampers is configured to seal a gas in an inner region between the first flexible portion and the second flexible portion. A coupler that couples the plurality of diaphragm dampers together includes holders that hold the rims of the plurality of diaphragm dampers. A gap is provided between the holder of the coupler and the welded portion of each of the plurality of diaphragm dampers.

摘要： A high-pressure fuel pump (10) includes a plunger (11), a pump housing (12), an intake valve (13), a discharge passage (14), a fuel seal member (18), and a fuel inlet conduit (34). The pump housing (12) includes a fuel pressurizing chamber (23), an intake passage (24a), a discharge passage (24b), a cylinder housing member (21), a cover member (31) that covers the cylinder housing member (21), and an intake gallery chamber (12g). The fuel inlet conduit (34) is connected to the cover member (31) and configured to introduce fuel into the intake gallery chamber (12g) from outside the cover member (31). The pump housing (12) includes a return passage (33e) that communicates the intake gallery chamber (12g) with a space surrounded by the plunger (11), the cylinder housing member (21), and the fuel seal member (18). A first end portion of the return passage (33e) on the intake gallery chamber (12g) side is positioned on an opposite side of the cylinder housing member (21) from the fuel inlet conduit (34).
