Apparatus for calibrating the rate of delivery of injection pumps for diesel engines

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