Abstract: A vacuum pump lubricant supply system has a lubricant reservoir and a wicking element. The body portion has opposed major surfaces and a finger. The lubricant reservoir has a major surface engaging one of the opposed major surfaces of the body portion so that lubricant can migrate through the engaging major surfaces into the body portion. The finger projects from the body portion to engage a lubricant transfer device provided on a rotor shaft so that lubricant can wick from the body portion to the lubricant transfer device via the finger. The body portion has an edge provided with a cut-out so that the major surface of the body portion that engages the major surface of the lubricant container has a total surface area that is less than the total surface area of the major surface of the lubricant container.

Abstract: A pump lubricant supply system has a lubricant reservoir and at least one contactor to engage a lubricant transfer device provided on a rotor shaft of a pump to transfer lubricant from the lubricant reservoir to the lubricant transfer device via the at least one contactor. The lubricant reservoir includes at least a first reservoir portion formed of a first elongate strip of porous material wound to define a first lubricant container body having a longitudinal axis that extends transverse to the longitudinal axis of the elongate strip.
