Title: HIGH-PRESSURE FUEL PUMP AND METHOD FOR PRODUCING SAME
Abstract:
Provided are a high-pressure fuel pump and a method for producing same that are capable of improving the degree of flexibility in the layout of members to be mounted onto a pump body. This high-pressure fuel pump is accordingly provided with: an intake joint 51 through which fuel is taken in; a pump body 1 in which a pressurizing chamber 11 is formed to apply pressure on the fuel taken in from the intake joint 51; and a discharge joint 12 through which the fuel pressurized in the pressurizing chamber 11 is discharged. The pump body 1 is formed such that at least a part of the lateral side thereof has a cylindrical-shaped portion 1a or a polygonal-shaped portion. The discharge joint 12 and/or the intake joint 51 is fixed at a location on the inner circumferential side InS of the outermost circumferential part of the cylindrical-shaped portion 1a or the polygonal-shaped portion of the lateral side.
