ABSTRACT:
For checking the rate of delivery of an injection pump for a Diesel engine, vertical vessel is provided having a movable bottom wall formed by a piston-like member: the latter, via a mechanical transducer, reads the displacements of the piston as a function of the quantity of liquid delivered to the vessel by the pump being tested, the stop point being the top level in the vessel. The top level is signalled by a photoelectric device which spots the overflow of the liquid from the vessel top immediately as it occurs. Count-up or count-down means are provided for reading out the displacements of the piston so that, knowing the number of revolutions of the motor which drives the pump being tested, the exact rate of delivery of the pump can be calculated without being disturbed by any external cause of accidental errors.
