Patent number: 11939981Abstract: A rotary disc valve is used in a fluid delivery system to control flow of fluid between multiple ports of a valve housing. The valve housing may include a valve body and a lid that closes an open end of the valve body. In addition, the valve may include a diverter and seal assembly that are disposed in the valve housing. The diverter is configured to rotate about a rotational axis and to control fluid flow through the valve housing. The seal assembly provides a dynamic seal that is fluid tight within a plane that is perpendicular to the rotational axis. The diverter, the valve body and the seal assembly cooperate to define a fluid passageway that is coaxial with the rotational axis and passes through the seal assembly.Type: GrantFiled: December 16, 2021Date of Patent: March 26, 2024Assignees: Robert Bosch LLC, Robert Bosch GmbHInventor: Thomas Chapman

Patent number: 11932340Abstract: A vehicle suspension pre-load management system is disclosed. At least one suspension component, such as a motorcycle shock absorber, has an expandable chamber that with increased volume of a nearly incompressible fluid increases the suspensions pre-load. In one embodiment the system utilizes a controller, a pressure sensor, a pump, and a number of solenoids in a manifold block to allow a user to set a desired pre-load level. In another embodiment the controller monitors the pressure of the chamber and maintains a desired pre-load setting. In yet another embodiment, the controller identifies a hard braking event such that would cause a brake dive and increases the pre-load to counter act the dive.Type: GrantFiled: December 4, 2020Date of Patent: March 19, 2024Assignees: Robert Bosch LLC, Robert Bosch GmbHInventor: Kurt Person

Patent number: 11668402Abstract: A rotary valve has a valve plug that is rotatable in a valve body about a rotational axis. Surface features of the valve plug and surface features of the valve body cooperate to provide a bearing by which the valve plug is rotatably supported with respect to the valve body. In addition, each of the valve plug and the valve body include a plurality of annular projections that encircle the plain bearing and axially overlap one another so as to form a labyrinth that surrounds the bearing. The labyrinth forms a fluid path that collects abrasive particles suspended in the fluid passing through the valve, whereby wear of the valve is reduced.Type: GrantFiled: September 30, 2021Date of Patent: June 6, 2023Assignees: Robert Bosch LLC, Robert Bosch GmbHInventors: Thomas Chapman, George Popovici

Patent number: 11655999Abstract: An environmental control unit, such as an HVAC or heat pump unit, includes a housing which contains four main components: a blower which draws air into the housing via an air inlet and exhausts air from the housing via an air outlet; a first heat exchanger that exchanges heat through the air and is located between the air inlet and the blower; a second heat exchanger, which exchanges heat through water and is disposed in the second area of the housing; and a compressor. The environmental control unit having a predetermined set of parts can be arranged in multiple configurations to meet installation requirements, where configurations include air entering from the left side or, alternatively, from the right of the environmental control unit. The configurations utilize the same parts and provide front-facing access to fluid connections and the control board.Type: GrantFiled: June 22, 2021Date of Patent: May 23, 2023Assignees: Robert Bosch LLC, Robert Bosch GmbHInventors: Armen Davtyan, Aya Kozono
