Two methods are employed for cooling the Tu-Flo ® 700
compressor during operation. The cylinder head is
connected to the engine’s cooling system, while the cylinder
has external fins for efficient air cooling.
All Tu-Flo ® 700 compressors utilize the engine’s pressurized
oil system to lubricate the internal moving parts. A nameplate
is attached to the crankcase to identify the compressor.
The nameplate displays a Bendix piece number or in some
cases an engine or vehicle manufacturer’s piece number,
along with a serial number.
DESCRIPTION
The function of the air compressor is to provide and main-
tain air under pressure to operate devices in the air brake
and/or auxiliary air systems
The Tu-Flo ® 700 compressor is a two cylinder, single stage,
reciprocating compressor with a rated displacement of 15.5
cubic feet of air per minute at 1250 R.P.M. The Tu-Flo
® 700
compressor is constructed from three major assemblies,
the head, the cylinder block and the crankcase.
The head houses the discharge valving and is installed on
the upper portion of the cylinder block. The cylinder block
contains the cylinder bores and inlet valves and is mounted
to the crankcase. The crankcase houses the crankshaft
and main bearings.
Various mounting and drive configurations, required by the
numerous vehicle engine designs, are available. Two
governor mounting pads are located on either side of the
cylinder block to provide convenient governor mounting.
