Publication number: 20240084181Abstract: A refrigerant composition includes R1225ye(E) refrigerant, a second refrigerant that is one of R1234ze(E) refrigerant and R32 refrigerant, and a third refrigerant that is one of R227ea refrigerant, R125 refrigerant, and R1234yf refrigerant. The refrigerant composition has a GWP of at or less than about 2000. A method of making a refrigerant composition includes mixing at least an amount of R1225ye(E) refrigerant, an amount of a second refrigerant, and an amount of a third refrigerant to obtain a refrigerant composition that has a GWP of at or about or less than 2000. A method of retrofitting a refrigerant composition in an HVACR system includes adding an amount of at least one refrigerant to a refrigerant composition to produce a retrofit refrigerant composition that includes R1225ye(E) refrigerant, a second refrigerant, and a third refrigerant.Type: ApplicationFiled: September 12, 2022Publication date: March 14, 2024Inventors: Michael Petersen, Stephen A.

Publication number: 20240018886Abstract: Systems and method for a cam phaser are provided. In some configurations, the cam phaser includes a drive member having a first mating surface, a driven member having a second mating surface, and a locking mechanism arranged between the first mating surface and the second mating surface. The locking mechanism is operable to contact the first mating surface and the second mating surface, in response to an outside force applied to the driven member that loads the locking mechanism. The cam phaser further includes an engaging member. The engaging member is configured to selectively actuate the locking mechanism to enable rotation of the driven member relative to the drive member. The cam phaser may include a reaction mechanism configured to receive additional force from an input mechanism and selectively transmit the additional force to the driven member to unload the locking mechanism.Type: ApplicationFiled: July 13, 2023Publication date: January 18, 2024Inventors: Michael Kujak, Austin Schmitt, Todd Wollenberg

Publication number: 20230243281Abstract: The present disclosure provides systems and methods to compensate for backlash within a cam phasing system. For example, compensating for backlash by commanding a predetermined amount of additional actuator movement to account for backlash within a cam phaser. According to some aspects, a spring is provided within a cam phaser to unidirectionally take up the backlash within the cam phasing system.Type: ApplicationFiled: February 1, 2023Publication date: August 3, 2023Inventors: Michael Kujak, Todd Wollenberg, Patrick Heithoff

Publication number: 20230050408Abstract: The systems and methods described herein provide an approach for cam phase angle control where an axial or rotational position of an actuator of a cam phaser has a direct relationship to the phase angle of the cam shaft, allowing for accurate cam phasing without the need for cam shaft or crank shaft position sensors. Providing phase angle adjustability without the need for crank shaft or cam shaft position sensors enables control of phase angle solely by sensing the axial or rotational position of the actuator of the cam phaser.Type: ApplicationFiled: August 10, 2022Publication date: February 16, 2023Inventors: Michael Kujak, Todd Wollenberg, Patrick Heithoff, Dean Wardle

Patent number: 11352916Abstract: A mechanical cam phasing system includes a stator, a cradle rotor, a first locking mechanism having a first locking feature and a second locking feature, a cage, and a second locking mechanism rotationally coupled to the cradle rotor and selectively moveable between a locking state and a phasing state. In the locking state, a clearance is provided between the cradle rotor and the cage to allow the cradle rotor to rotate relative to the cage and lock the first locking feature or the second locking feature. In the phasing state, the clearance between the cradle rotor and the cage is reduced to ensure rotational coupling between the cradle rotor and the cage in at least one direction, which displaces the first locking feature or the second locking feature relative to the cradle rotor and enables the cradle rotor to rotate relative to the stator.Type: GrantFiled: January 22, 2021Date of Patent: June 7, 2022Assignee: HUSCO Automotive Holdings LLCInventors: Michael Kujak, Austin Schmitt, Alexander Schlarmann

Patent number: 11053990Abstract: Systems and method for a two-way clutch are provided. In some configurations, the two-way clutch includes a driven member having a first mating surface, a drive member having a second mating surface, and a locking mechanism arranged between the first mating surface and the second mating surface. The locking mechanism is operable to contact the first mating surface and the second mating surface, in response to an outside force applied to the drive member that loads the locking mechanism. The two-way clutch further includes an engaging member. The engaging member provides a predetermined interference on the locking mechanism to hold the locking mechanism off of at least one of the first mating surface and the second mating surface, when the locking mechanism is in an unloaded state.Type: GrantFiled: December 19, 2018Date of Patent: July 6, 2021Assignee: HUSCO Automotive Holdings LLCInventors: Michael Kujak, Allen Tewes, Austin Schmitt
