Abstract:
An arrangement for an injection pump in an internal combustion engine, especially a large diesel engine, in which the injection pump (2) is provided with a pressure medium controlled feed control valve (11), the flow circuit of which includes a pressure medium source (14), from which pressure medium is pumped through a delivery duct (16a) into a feed duct (17, 18, 20, 21, 22, 22a), which is provided with a non-return valve (23) and is connected to a pressure chamber (13) affecting said control valve (11) and to a spill passage (24) to be switched off by means of a solenoid valve (25), whereby closing of the solenoid valve (25) is arranged to provide a pressure increase in the pressure chamber (13) and, thus, a change of the state of the control valve (11), characterized in that said feed duct (17,18,20,21,22,22a) between the delivery duct (16a) and the control valve (11) is dimensioned to be long and narrow and is arranged at least to its main part to be a stationary part of the injection pump (2), of its supporting construction (3) or of a stationary construction unit attached to the injection pump or its supporting construction.
