ABSTRACT:
Disclosed herein is a throttle control for an engine including a housing supporting a control lever for rotation relative to a neutral position, a throttle lever movably mounted on the housing and adapted to actuate the engine throttle, a throttle drive member including a drive pin and mounted for rotation in response to movement of the control lever from the neutral position, and a cam member connected between the throttle lever and the throttle drive member. The cam member includes a cam track receiving the drive pin and having a shape effective to displace the cam member relative to the throttle drive member, transversely relative to the rotational axis of the throttle drive member, so as to move the throttle lever in response to rotation of the throttle drive member.
In one embodiment, the control further includes a shift lever movably mounted on the housing and adapted to actuate the engine clutch and a shift drive member drivingly connected to the shift lever for actuating the engine clutch in response to movement of the control lever from the neutral position. The cam track is arranged so that the cam member, and thus the throttle lever, remains in an engine idle position during initial movement of the control lever from the neutral position to actuate the engine clutch and so that further movement of the control lever from the neutral position causes translatory movement of the cam member to advance the engine throttle.
