GOVERNOR
BENDIX-WESTINGHOUSE D-2 TYPE
DESCRIPTION
The air compressor governor along with the
compressor unloader mechanism automatically limits
system pressure to a predetermined range by opening
unloading valves and stopping
compression
when
system pressure has been built up to maximum pressure
limit and by closing unloading valves and starting
compression when system pressure has dropped to
minimum pressure limit.
The D2 governor has a piston upon which air
pressure acts to overcome the pressure setting spring
and control the inlet and exhaust valve to either admit or
exhaust air to or from the compressor unloading
mechanism.
Type D2 governors can be attached hed to the
compressor or mounted remotely.
They are adaptable to
either mounting.
Connections in this system are to the
reservoir and compressor unloading ports.
They also
have an exhaust port.
