In this paper, I had not so many experiences to find the firm results, but the tendency was found as follows.
That is, the jet discharge from the nozzle of the motor sprayer used various type mechanics was irregular even when the same nozzle was used and the mean pressure worked upon the fluid was same.
In theoreticaly, the jet discharge was the function of the pressure and approached velocity of the fluid, but in addition to above it was found that it was affected by the pressure wave, the figure and the point of the peak value of the ripple current caused by the crank mechanics, in this experience.
θ max, the point of peak value, became the smaller, the discharge more increased. The capacity of the air chamber had directly no concern with the discharge, but it was thought that the capacity had an effect on the figure of the ripple.
