Pressure relief valve assembly
The pressure relief valve is mounted in the
luggage compartment between the pump and the
filter. The unit consists of three parts, namely an
adjustable valve, a strainer housing and a brass
'r'
piece.
Fuel from the pump enters and leaves the
assembly through the 'T' piece. The valve is set to
provide a constant pressure of 106 - 110 p.sl. (7'45
- 7'70 kgf/cm
2
)
to the metering distributor and fuel
in excess of this pressure is fed back to the tank
through the strainer housing and valve.
Injectors
The injectors are fitted into the inlet manifold
and secured in pairs by a clamping plate. Fuel pipes
from the metering unit are secured to the injectors by
union nuts. The unions are numbered one to six for
identification purposes. A poppet valve in the injector
is set to open at 50 p.sl. (3'52 kgf m
2
)
to provide a
60° hollow cone spray of atomised fuel.
