Abstract
A constant level oiler is provided which is ventilated in such a manner so as to eliminate the need for a large surge chamber. Such an oiler has an advantage in that the problems associated with the fluid surge resulting when the lubricated machine is shut down are eliminated. Furthermore, since a large surge chamber is unnecessary in the present device, the attendant costs associated therewith are also eliminated.
