pistons have carefully fitted cast iron snap rings,
with a special device to prevent leakage past the
joints. The piston rods are made of a selected
grade of tough steel, and secured to the piston
with taper fits and lock nuts.
With the speed required of "WJ-3" compressors,
the question of adequate and reliable lubrication
becomes of great importance. The well known
splash system for supplying oil to the working
parts, while simple and reliable, is not suited to
fast running engines and compressors. The oil
used in this system is contained in the main
frame. The constant and violent agitation of the
oil by the moving parts keeps any grit or foreign
substance in the oil in suspension and delivers it
repeatedly through the bearings, where, even if
the grit is not harsh enough to cause heating,
it produces unnecessary wear.
The crank shaft bearings, crank and crosshead
pins and crosshead guides, of both high and lowpressure
members, are supplied with stream lubrication.
From the main oil reservoir, in the bottom
of the horizontal main frame, underneath the
crank shaft, a small plunger pump, driven from
connections attached to the air valve gear, and
with all of its working parts submerged in oil,
delivers oil to a reservoir at the top of a stand
pipe, high enough to insure the delivery to the
highest point at which lubrication is needed.
From this reservoir oil flows to the points specified.
The amount of oil flowing to each point is
regulated by adjustable sight feed connections.
The pump is designed to pump an amount of oil
greater than maximum requirements, and the excess
from the overhead reservoir is returned by
an overflow to the main reservoir in the horizontal
frame. After the oil has passed through the
various bearings, it flows back to the main reservoir
to be used again. The air c> Under and rolling
inlet valves are oiled from a separate fivefeed
positive oil pump of special design, driven
from the air valve gear. Each feed may be regulated
separately.
The rate of feed of oil, to all points lubricated,
may be observed by the operator from the engine
room floor. All working joints in the air valve
gear are lubricated with grease cups. The outboard
bearing supporting the end of the crank
shaft is independently lubricated by a supply of
oil contained in a well underneath the bearing, to
which it is delivered by ring oilers.
The water circulation for the cylinders and
intercooler has but one inlet and one outlet. Entering
at the bottc ,, of the low pressure cylinder,
water passes then L- through the intercooler and
high pressure cylinder, leaving the latter at the
top. This arrangement provides a positive circulation,
with no danger of entrapping air in the
water spaces.
