Abstract
A rotary input drive member (34) is connected by external splines (44) to internal splines (50) on an intermediate drive member (48). The intermediate drive member (48) is connected by external splines (52) to internal splines (46) on an output drive member (38). The output drive member (38) is connected by gear teeth (186) to a gear bracket (188) that is on a fuel pump shaft (192). The intermediate drive member (48) is connected to a drive plate (100) which is movable axially back and forth along guide pins (106) which are parallel to the axis of the fuel pump shaft (192). The intermediate drive member (48) is restrained against movement axially relative to the drive plate (100) but is free to rotate relative to the drive plate (100). The sides of the drive plate (100) include trunnions (130) which are received in diagonal slots (138, 140) provided in side members (134, 136) of a yoke that in addition to the side members (134, 136) includes a top member (132). Up and down movement of the yoke (132, 134, 136) causes the drive plate (100) to move axially. Axial movement of the drive plate (100) causes the intermediate drive sleeve (48) to move axially. The splines (44, 50, 52, 46) a…
