Patent number: 9599127Abstract: The invention relates to an system for supplying a hydraulic circuit with hydraulic fluid. The system includes a working reservoir and an auxiliary reservoir connected to the working reservoir by a hydraulic line. An air pump has an inlet connected to a suction line that opens into a liquid-free portion of the auxiliary reservoir so that a negative pressure can be built up in the auxiliary reservoir relative to the atmospheric ambient pressure. The air pump inlet is also connected to a control line, which comprises a control opening which is covered by the hydraulic fluid in the working reservoir, at least before the air pump is started up.Type: GrantFiled: January 21, 2014Date of Patent: March 21, 2017Assignee: DEERE & COMPANYInventors: Scott R. Wiens, Marcus Bitter, Christian Brueser, Harm-Hendrik Lange, Helmut Schaefer

Patent number: 9429224Abstract: A high speed gearbox includes a housing which encloses a rotating gear and a volume which contains oil and air. The gear has an outer first surface exposed to the volume and has a second surface exposed to the environment. A vent arrangement includes first and second passages formed in the gear. The second passage extends axially part way into the gear and has an outer end exposed to the second surface. The first passage extends radially from the first surface to the second passage. A check valve is mounted in the second passage and permits one-way flow of air from the volume to the environment.Type: GrantFiled: February 17, 2014Date of Patent: August 30, 2016Assignee: DEERE & COMPANYInventors: Scott R. Wiens, Eric T. Lammers

Patent number: 9327692Abstract: In a vehicle having a brake line communicating a brake pressure to a brake, a lubrication control circuit controls flow of lubrication fluid to a brake cooling circuit. The lubrication control circuit includes a lube pressure control proportional valve and a shuttle valve. The lube pressure control valve communicates lube fluid to an inlet of the shuttle valve when lube pressure is above a threshold. When the brake is applied, brake pressure in a pilot line operates on the shuttle valve and the shuttle valve communicates lube fluid to the brake cooling circuit and blocks lube flow to other cooling or lube circuits.Type: GrantFiled: May 3, 2013Date of Patent: May 3, 2016Assignee: DEERE & COMPANYInventor: Scott R.

Patent number: 8151818Abstract: The invention concerns a system for supplying hydraulic fluid to a hydraulic system, with an operating reservoir that accepts the hydraulic fluid provided for the operation of the hydraulic system and an auxiliary reservoir connected to the operating reservoir over a hydraulic line for intermediate storage of hydraulic fluid withdrawn from the operating reservoir. According to the invention, an air pump is available that is connected on the one hand on its low pressure side to a suction line that ends in a fluid free area of the auxiliary reservoir, so that a negative pressure can be built up in the auxiliary reservoir as against the external atmospheric pressure, and that is connected, on the other hand, to a control line that is provided with a control opening that is covered by the hydraulic fluid in the operating reservoir at least before the air pump is put into operation.Type: GrantFiled: September 1, 2009Date of Patent: April 10, 2012Assignee: Deere & CompanyInventors: Scott R.
