Patent number: 11898695Abstract: A progressive distributor for lubricant includes a housing block having an inlet and a plurality of outlets and a plurality of metering pistons received in associated piston bores in the housing block. Each piston bore is associated with two lubricant outlet bores, and each metering piston is displaceable and configured to alternatingly release the one or the other lubricant outlet bore in order to dispense the metered lubricant amount to the lubricant outlet bore. The piston bores are fluidically connected to the lubricant inlet bore and to each other via connecting bores in order to transfer lubricant to the other piston bores. A dummy piston is disposed in one of the piston bores that permanently closes both the lubricant inlet bore and both lubricant outlet bores, and includes at least one bypass passageway that fluidically connects two of the connecting bores to each other.Type: GrantFiled: March 2, 2021Date of Patent: February 13, 2024Assignee: SKF LUBRICATION SYSTEMS GERMANY GMBHInventors: Dieter Hess, Juergen Kreutzkaemper, Markus Mandera, Andreas Schoenfeld, Stefan Schuermann, Dennis Zahn

Patent number: 10962130Abstract: A lubricant reservoir system includes a lubricant reservoir having an interior wall and an inlet for receiving lubricant from a supply. A follower device in the reservoir contacts the interior wall of the reservoir in a sliding and sealing manner, and the follower device is movable up and down in the reservoir from a first position to a second position in response to a changing lubricant level. A valve is in fluid communication with the inlet and is configured to selectively prevent a flow of the lubricant through the inlet. A connector operatively connects the follower device to the valve unit such that the flow of the lubricant through the inlet is prevented when the follower device is in the second position. The connector is configured such that the valve is positionable independently of the reservoir.Type: GrantFiled: January 30, 2018Date of Patent: March 30, 2021Assignee: SKF LUBRICATION SYSTEMS GERMANY GMBHInventors: Markus Mandera, Dieter Hess, Tobias Mueller, Andreas Schoenfeld

Patent number: 10927834Abstract: A lubricant supplying device includes a feed pump that serves to pump lubricant from a lubricant reservoir to at least one lubrication point. A method for operating the lubricant supplying device includes measuring at least one operating parameter, such as temperature (T), of at least one part of a system to be lubricated and/or of the lubricant and/or of the environment. The at least one measured operating parameter (T) is supplied to a controller, where a required volumetric flow ({dot over (V)}target) of lubricant is determined based on a stored functional relationship ({dot over (V)}target=ƒ (T)) that generates the required volumetric flow ({dot over (V)}target) based upon the measured operating parameter (T). The feed pump is then actuated in order to achieve the determined, required volumetric flow ({dot over (V)}target).Type: GrantFiled: March 11, 2015Date of Patent: February 23, 2021Assignee: SKF LUBRICATION SYSTEMS GERMANY GMBHInventors: Armin Buergy, Dieter Hess, Andreas Schoenfeld, Stefan Schuermann
