The pump is shown rotated 180 degrees about a vertical axis.

I put a flashlight inside the front cover in this picture  to try and show
that the vent oil does indeed insure the oil reservoir is at atmospheric
pressure by venting the reservoir to the inside of the front cover. 
 
The oil scraper scrapes oil off of the surface of the shaft to the
oil reservoir.
