Latest Patents
One of Patrick McMullen's key inventions is a vacuum pump with an improved back-up bearing assembly. This design allows the rotor to spin down safely without damaging the pump if the primary bearing system fails. The drive shaft of the rotor is tubular and houses the back-up bearing assembly within its hollow interior. The back-up bearings are mounted onto a tubular center shaft, which is coaxial with and located inside the drive shaft. An axial position sensor is integrated within the center shaft, utilizing light emitted from its light emitter, which is reflected by a target inside the drive shaft to detect the relative axial position of the drive shaft concerning the center shaft. Additionally, a polymer sleeve is attached to the end of the drive shaft, serving as a thermal compensator that restricts the axial movement of the drive shaft. This innovative design has resulted in 1 patent.
