    Abstract: Timing mechanism for adjusting the angular disposition of an engine fuel pump cam shaft in response to changes in engine speed which comprises flyweight means to adjust the angular relationship of two rotating elements. In the present case, these elements are not coaxial with the fuel pump cam shaft, but one is connected thereto by a gear train to isolate the flyweight means from shock or impulse forces which are transferred through the cam shaft and to increase inertia without undue increase in mass and complexity.

    Abstract: A crankcase ventilating means comprises a spring-biased valve means adapted to open to vent gases from the crankcase of an internal combustion engine to the intake manifold thereof when the pressure of such gases exceeds a predetermined level. The opening and closing of the valve means is automatically controlled by pressure level variations occurring in a control chamber normally communicating with ambient air pressure, via a pressure sensing conduit, during ''''on land'''' operations. An open end of the conduit is positioned adjacent to a crankshaft sealing area to sense the increasing pressure level occasioned thereat due to progressive submersion of the engine in water. Thus, the pressure level in the crankcase, required to open the valve means, will automatically increase in direct proportion to the increased depth of engine submersion.
