Abstract
First and second cam members are engageable in a fuel injection pump. A first device urges the first cam member toward the second cam member to obtain engagement between them. The first cam member reciprocates as it moves relative to the second cam member when the first and second cam members are in engagement. A plunger connected to the first cam member reciprocates with the first cam member. The plunger defines at least part of a pumping chamber which contracts and expands as the plunger reciprocates. As the pumping chamber expands in a fuel intake stroke, fuel moves into the pumping chamber. As the pumping chamber contracts in a fuel compression stroke, the fuel moves out of the pumping chamber. A second device resists movement of the plunger in the fuel compression stroke.
