Abstract: A method, and associated apparatus, or applying fluid lubricant to hydrodynamic bearing. Clearance spaces of the bearing which are to be filled with the fluid lubricant are evacuated. The fluid lubricant is then applied to the clearance spaces.

Any pockets of air, or other gas, trapped within the bearing are collapsed as the clearance spaces are returned to the ambient pressure levels. The method is amenable to a high volume, assembly line-like process wherein large numbers of bearings may be filled with the fluid lubricant in a short period of time. A conveyor conveys the bearings into a pool of fluid lubricant in a vacuum tank having a pressure level adjustable between an ambient pressure level and an evacuated pressure level, through the pool of fluid lubricant, beyond the pool, and out of the vacuum tank.

Abstract: Fluid proportions system for proportioning a fluid intermittently at various places. This fluid comes from a storage point and is added by an intermittently operating pump to a proportioner, which feeds a fixed volume of fluid to an outlet more or less independently of the pressure.

A forced return movement of the piston is thereby achieved. Proportioning of fluid is realized by the proportioning fluid itself while return movement in the proportioner of the piston is realized by the control fluid.

For this purpose the dosing device has a housing with a defined volume in which a piston is movable in an axial direction to define two chambers.

Thus, always a precisely measured volume of lubricant is discharged from one chamber while the same volume is being filled into the other chamber and vice versa. A coupling adapter may be used for a quick reversal.
