Abstract

PURPOSE: To prevent a diaphragm and an upper body from separating from each other and fuel from leaking by a method wherein the whole peripheral edge of a diaphragm is sandwiched by the whole peripheral lower edge of an upper body and the lower end is fixed by a cover to the upper of a lower body.
CONSTITUTION: The whole peripheral edge of the diaphragm 1 for sending fuel under pressure is calked and pinched so that it is covered with the whole peripheral edge and this pinched part or the low end part of the upper body is calked by a cover 9 and fixed to the upper end part of the lower body 3. In this case, the pump mechanism is made up in the same way as conventionally. The fuel absorbed by vertical motion of a diaphragm subassembly 8 from an inlet tube 6 is discharged from an outlet tube 7. As a result, although the joined edge of said each body 2, 3 is separated by the collision of cars or the like, no clearance occurs on the calked part of the upper body 2 and the diaphragm 1 and leakage of fuel from a fuel chamber can be prevented.
