Abstract
A fuel metering pump assembly for delivering fuel to a combustion chamber of an internal combustion engine has a crankcase, a throttle and at least one cylinder. A housing has a fuel inlet and a fuel outlet, and a metering arrangement is disposed in the housing between the fuel inlet and the fuel outlet. The metering arrangement has a plunger rod movable in a chamber between the fuel inlet and the fuel outlet to control the flow of fuel therefrom, and a movable camshaft is engageable with the plunger rod to selectively deliver fuel from the fuel outlet at a predetermined pressure and volume in response to pulses from the crankcase. A motive device is mounted on the housing in direct engagement with the camshaft. The motive device is responsive to the position of the throttle to move the camshaft relative to the plunger rod so as to vary the fuel delivered from the fuel inlet to the fuel outlet.
