A control system for an engine transmission provided with a coupling mechanism for engaging or disengaging coupling of the transmission. The control system has one or more valves movable between two positions for controlling engagement and disengagement of the coupling mechanism. The valves are connected to an automatic control unit which has an intermittent signal supply trigger for supplying an intermittent pulsed signal to the valves, thereby providing an intermittent movement of the valves between the two positions.

Angle gearing, especially for a marine outboard drive unit

A combined bearing and fluid supply unit is disclosed primarily for use in a power transmission system for marine vessels. The unit has a housing having a circular opening. The circular opening is delimited by an inner surface of the housing, and the inner surface is provided with one or more first circumferentially extending channels which respectively accommodate one or more bearings. The bearings are adapted to support a shaft passing through the circular opening. The housing also includes a first bore extending radially from a second circumferentially extending channel in the inner surface of the housing to an outer surface of the housing. This second circumferentially extending channel is adapted to convey fluid passing from the first bore to a first internal passage in the shaft. Preferably, this fluid is used to actuate a clutch carried on the shaft in a given direction. A second radial bore and a third circumferentially extending channel may be provided in the housing, in communication with the bearing, in order to provide lubricating fluid for the bearing. A third radial bore and a fourth circumferentially extending channel may be provided so as to actuate the clutch to rotate the shaft in the opposite direction.
