The water flow regulator valve
no. 2
is mounted
directly onto the muffler.
TYPICAL
1. Water supply hose of regulator valve
2. Regulated water to injection fitting
3. Water injected into the muffler
NOTE:
The water injected into the muffler is not
regulated by the tapered needle of the valve. In-
stead, a calibrated water injection fitting controls
water flow into the muffler. Refer to the following
chart.
The water flow regulator valve has a calibrated
spring and a tapered needle which regulate the
injected water in the tuned pipe.
CAUTION:
Do not change anything on the wa-
ter flow regulator valve, otherwise serious en-
gine damage can occur. In many countries it is
illegal to tamper with this valve as this will af-
fect the EPA certification.
At low speed, water pressure in the supply hose
of the regulator valve is not sufficient to overcome
the spring of the regulator valve; more water is
being delivered to the injection fitting at the tuned
pipe.
LOW SPEED OPERATION
1. Water entering regulator valve
2. Water exiting regulator valve (less restriction)
3. Water injected in the muffler
At higher speed, water pressure increases in the
supply hose of the regulator valve and gradually
overcomes the return spring of the regulator valve.
Less water is being delivered to the injection fitting
at the tuned pipe.
HIGH SPEED OPERATION
1. Water entering regulator valve
2. Water exiting regulator valve (more restriction)
3. Water injected in the muffler
