Regulator Function
The LPG is gasified by depriving the engine coolant, led into the regulator, of heat. The regulator consists of chamber
A where LPG vaporization starts, chamber B (first reducing chamber) where the gasified LPG pressure is reduced,
chamber C (second reducing chamber) for reducing the pressure down to almost atmospheric level to supply fuel
using the adopter venturi vacuum, and chamber D for forced fuel supply during engine start and idling.
LPG flowing into chamber A of the regulator pushes elastic face valve 1 open by vapor pressure allowing it to enter
first reducing chamber B where it is vaporized by pressure reduction. When the pressure in chamber B becomes in
the range of 24.5 to 34.3 kPa (0.25 to 0.35 kgf/cm
2
) (3.6 to 5.0 psi), first diaphragm pushes first regulator spring, so
first diaphragm hook acuates first valve lever to close elastic face valve 1. When LPG flows out to second reducing
chamber C, the first pressure drops and first valve lever is operated by first regulator spring to open elastic face valve
1 to cause fuel to flow into first reducing chamber B again. Opening and closing of elastic face valve is repeated to
maintain the first pressure at a fixed level. The pressure of the fuel entering from chamber B into chamber C through
elastic face valve 2 is reduced to atmospheric level. Chamber C is connected to the adapter.
The vacuum of the ventury nozzle at the adapter operates second diaphragm to open elastic face valve 2 via second
valve lever. The valve is closed by the force of second regulator spring to maintain a constant pressure (atmospheric
pressure).
