Abstract
There is disclosed an oiler assembly for lubricating at least one lubrication point capable of drawing and maintaining a vacuum. The assembly includes a source of supply of oil lubricant and feed units corresponding in number to the lubrication points and connected to the common supply. The feed units have a suction outlet and include a standpipe communicating with the supply of oil lubricant. The feed units further include a sump separated from the corresponding standpipes by a common wall. At least one wire or rod element extends over the common wall and delivers oil lubricant from the standpipe to the sump. The feed units also include passage means placing the suction outlet in communication with the sump with a portion of the passage means being disposed higher than the common wall. The oil lubricant feed rate is adjustable by the removal or addition of wire or rod elements between the standpipe and sump.
