Function of system VRC-M
The vacuum in the VRC-M system is created by piston vacuum pump (Item 2), which is powered via a
rubber belt of electric motor of pumping monoblock. For dispensers with pressure system is installed in
a compact unit - electric motor with integrated vacuum pump.
Outgoing gasoline vapors from the tank car when dispensing gasoline are drawn special adapter nozzle
(item 6), through the channel in the body to control flow through the nozzle hydromechanical valve
integrated into nozzle and into the inner coaxial hose DN 8 (Item 5). The coaxial spacer (Item 4) pairs
are fed to a flexible connecting pipe (Item 3), goes on to piston pumps (Item 2). The piston pump (item
2) are pushed through a flexible pipe to the exhaust pipe vapor (Item 1). connected to the interior of
the storage tank (usually from the lowest octane gasoline.
Optimal flow of vapor is dynamically regulated by proportional hydromechanical valve depending on the
actual flow of liquid gasoline nozzle.
Proper function of vapor recovery is indicated by shining symbol of two arrows (Fig. 9) on the display of
electronic counter on the appropriate side of the dispenser.
