The open end of the cup shaped portion is closed by a plug portion which accommodates the second portion of the rotor. The two parts of the rotor are connected to each other so as to rotate together, and the first portion of the rotor together with the cup shaped portion of the body part house the low pressure fuel channels of the apparatus while the plug portion and the second portion of the rotor house the high pressure passages and components of the apparatus.
