Little freezer compressor photos.

File:  freezer1.jpg

Shows at the top of the picture the "ball" split
in half and the top half removed and set off to
the left.  You can see the field windings in
copper, with the armature going down through the
center of the compressor.  Note: there is NO bearing 
on the top end of the compressor armature shaft.
It is suitable supported by bearings at the bottom 
and obviously well balanced enough not to cause a 
problem.

In the bottom of the picture you will see the bottom
of the ball with the electrical connections on the
left, the various copper tubing which is connected
through the case, and the four spring posts on which
the compressor unit rests.  The whole pump just sits
on these springs and floats around as needed.

This photo shows the compressor removed from the
ball, and you are looking at the "bottom" of the
compressor.  You can see the four posts that sit
down into the springs for support
In the center, you can see the "crankpin" which
is connected to the connecting rod going into the
cylinder where the piston is located.  You can see
the "cylinder head" with the bolts holding the
reed valve plates to the head.

The bottom of the photo shows the reed valve pack
disassembled, and also the two "chambers" disassembled
(and I don't have a clue what they are for) but
they are "ball shaped" also, have one screw down
through the center of them with copper washers
on them, and the one on the left has a copper line
coming from it.  It also had an extra "plate" in
the sandwich assembly.  The one on the right had
no extra plate, and no copper coming from it.  
You can see the little piston in the bore just above the
disassembled reed valve plates.  The bore is approx .75
and the stroke is approx .5

Also note on the end of the "crankpin" where the
connecting rod connects, there is a small tube, bent at
a slight angle.  At the bend in the tube, there is a 
small hole.  The end of the tube is in "line" with
the centerline of the crank, so although it rotates,
it does not "inscribe a circle"... but it picks up
the oil, and since the tube is bent, the oil is
flung out the small hole at the bend in the tube.
Kinda neat for an oil slinger, I guess.

Hope you enjoyed... Anyone need any of these parts??
