Abstract
A nozzle assembly adapted for a fluid injector having a ram, includes a plunger assembly having first and second driving members. The first and second driving members are apart according to a predetermined first distance. The second driving member is spaced apart from the ram according to a predetermined second distance. The first and second distances are resiliently maintained by a resilient spring member operatively disposed between the two driving members. One of the first and second distances is selected to be the smallest and thereby controls the maximum pressure at which fluid is expelled from the nozzle assembly.
