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).

Abstract: A side thruster comprises a valve, a first water passageway, a second water passageway, a third passageway, a fourth passageway and a pump having an inlet and an outlet. The valve housing includes a first, second, third and fourth ports and a two-position barrier situated within the housing. When in the first position, the barrier connects the first port with the second port and the third port with the fourth port. When in the second position, the barrier connects the second port with the third port and the fourth port with the first port. The first passageway extends between the first port and a first side opening on a first side of the boat. The second passageway extends between the third port and a second side opening on a second side of the boat. The third water passageway extends between the second port and the pump outlet. The fourth water passageway extends between the pump inlet and the fourth port.

Abstract: Start of fuel delivery for a fuel-injected engine having separate unit injectors is adjusted by effecting a positional adjustment of camshaft lobes on a camshaft. The camshaft is used to operate the unit injectors, as well as control exhaust valve operations. By separately controlling the position of the cam lobes which operate the unit fuel injectors, a change it start of fuel delivery is effected. A change in relative position of the cam lobes is accomplished by shifting a guide rod within a hollow body of the camshaft. The change in position of the guide rod, in turn, effects a change in position of the cam lobes which are connected to the guide rod.

Abstract: An electronic timing system for controlling the injection angle of a fuel pump, comprising an input sleeve (12), an output drum (36), an intermediate drive sleeve (30), a drive plate (60), a drive yoke (76), and a stepper motor (90). Drive sleeve (30) includes a pair of radially inwardly and outwardly projecting drive pins (32), and drum (36) and input sleeve (12) both include helical slots (38) and (16), respectively, through which pins (32) project. Vertical movement of yoke (76) causes axial movement of drive plate (60) and drive sleeve (30), which causes a relative rotational adjustment of angle between input sleeve (12) and output drum (36), for retarding and advancing the timing of the fuel injection system.
