Title: Innovations of John R Graber, Jr.

Introduction

John R Graber, Jr. is an accomplished inventor based in Murrysville, PA (US). He has made significant contributions to the field of vacuum technology, particularly with his innovative designs that enhance efficiency and performance.

Latest Patents

Graber holds a patent for a Multi-stage Helical Screw Rotor. This invention involves a vacuum pump that features an inlet port and an exhaust port. Gas from an enclosure connected to the inlet port is pumped to the exhaust port by first and second rotors mounted on first and second shafts extending through a pump chamber. The rotors are connected with shaft sections that include a lobe extending from the shaft sections and a mating channel defined in the other. The lobes matingly engage the channels during rotation of the rotors to form a suction section. This suction section compresses a volume of gas entering the pump from the inlet port, reducing the power consumed to move the volume of gas through the pump chamber more easily and increasing pump efficiency. Graber's innovative design has the potential to revolutionize vacuum pump technology.
