ABSTRACT:
An hydraulic mechanism constructed to facilitate termination of fuel delivery by a fuel injection pump includes a piston slidable within a bore which opens into a chamber communicating with the pump. The piston is biased towards an end wall of the chamber and in the end wall is an inlet port. The piston defines a sealing surface engaging with the end wall about the port and a control valve connects the port with the chamber. When the valve is closed and the piston is in contact with the end wall fuel can be delivered by the pump but as soon as the valve is opened the piston is displaced away from the end wall to absorb the fuel delivered by the pump.
