Abstract
Measuring apparatus for measuring the quantity of calibration fluid delivered by engine-fuel injection apparatus, in which calibration fluid is passed into a hollow cylinder on one side of a piston to displace the latter in one direction along the cylinder and pressurized gas is passed into the cylinder on the other side of the piston to displace it in the other direction and so drain calibration fluid from the cylinder.
