More Information
Summary:A fuel injection nozzle includes a fuel pressure actuated valve member slidable in a bore and engaged by a piston slidable in a cylinder of smaller diameter than the bore and connected thereto the space defined between the piston and valve member communicates by way of a non-return valve with the end of the cylinder remote from the bore. In operation fuel is displaced from said space past the non-return valve and the pressure in the end of the cylinder remote from the bore rises to increase the force acting to maintain the valve member in the closed position.
