Fig. 2.208. Check of the regulator of pressure of fuel


Use a magnetic rack with the indicator which leg is established on a pressurization pressure regulator valve drive rod end face (as far as possible coaxially with a rod) (fig. 2.208).
Give gradually pressure upon pressure regulator pneumatic actuator by means of the vacuum pump.
With a pressure of 331 Mbar the course of a rod is equal to 1 mm.
With a pressure of 544 Mbar the course of a rod is equal to 5 mm.
