8-1. Mechanism
As illustrated in Fig. 3, the Model NV 83A2 can be generally divided into four sections:
output section, control valve section, driving section and magazine section.
Although the output section and the valve section are basically common to those of the Model NV 83A, most of
the parts of the driving section and the magazine section have been newly designed.
Primary differences from the Model NV 83A are described below.
