Patent number: 11286932Abstract: A blower may include a blower housing that may include a plurality of rotor chambers and a plurality of rotors. The plurality of rotors may be substantially identical and each may include a twist angle and a helix angle. The rotors and the blower housing may be configured to create internal fluid compression when the rotors are rotating at a first rotational speed and not to create internal fluid compression when the rotors are rotating at a second rotational speed. The rotors and the blower housing may be configured to create the internal fluid compression without backflow slots in the blower housing. The twist angle may include the angular displacement of lobes of the plurality of rotors between axial ends of the plurality of rotors. The helix angle may be a function of the twist angle and a pitch diameter of the plurality of rotors.Type: GrantFiled: August 30, 2019Date of Patent: March 29, 2022Assignee: Eaton Intelligent Power LimitedInventor: Matthew G.

Patent number: 9938974Abstract: A supercharger assembly has a rotor housing defining a chamber. A rotor is within the chamber and has an end with an end face. A seal has a seal face adjacent the end face. The seal face and the end face have complex topographies configured to be complementary to define a gap therebetween. The complex topographies can be, but are not limited to, interfitting concentric annular channels. The gap functions as a tortuous flow path to inhibit fluid flow past the end face. A method of manufacturing a supercharger assembly is also provided.Type: GrantFiled: December 23, 2014Date of Patent: April 10, 2018Assignee: EATON CORPORATIONInventor: Matthew G. Swartzlander

Patent number: 9822781Abstract: A Roots-type blower may include first and second meshed, lobed rotors disposed in first and second chambers of a housing. Each lobe may have first and second axially facing end surfaces defining a twist angle that may be a function, at least partially, of the number of lobes on each rotor. A blower housing may include a bearing plate that may include one or more internal pressure relief ports. A pressure relief port may be configured to relieve fluid pressure from a trapping area that may form between first and second meshed rotors.Type: GrantFiled: December 19, 2014Date of Patent: November 21, 2017Assignee: Eaton CorporationInventor: Matthew G.

Publication number: 20170260981Abstract: A segmented rotor assembly built from individual rotor segments is presented. In one aspect, the segmented rotor assembly is defined by a plurality of lobes extending between a first lobe end and a second lobe end. Each lobe is constructed from a pair of identically shaped lobe segments mated to each other. Each lobe segment is provided with a helical twist extending between a first segment end and a second segment end. The constructed lobes can then be mated to each other to create a wholly formed rotor.Type: ApplicationFiled: March 9, 2017Publication date: September 14, 2017Inventor: Matthew G. Swartzlander
