BENDIX D-2 GOVERNOR User Manual

SD-01-503
DESCRIPTION
The D-2
™
governor, operating in conjunction with the unloading
mechanism, automatically controls the air pressure in the
air brake or air supply system between a maximum (cut-
out) pressure and a minimum (cut-in) pressure. The
compressor runs continually while the engine runs, but the
actual compression of air is controlled by the governor
actuating the compressor unloading mechanism which stops
or starts the compression of air when the maximum or
minimum reservoir pressures are reached.
D-2
™
governors are provided with mounting holes which allow
direct mounting to the compressor or remote mounting.
Porting consists of three reservoir ports (1/8 inch P.T.),
three unloader ports (1/8 inch P.T.) and one exhaust port
(1/8 inch P.T.).
