  • Patent number: 10851689
    Abstract: A gas turbine engine in a shutdown mode comprises one or more rotatable shafts, a first oil sump, a second oil sump, and an oil drainage conduit fluidically connecting the first oil sump and the second oil sump. The one or more rotatable shafts are oriented with an axis of rotation less than 90 degrees from vertical. The first oil sump has a selected critical vertical level. The second oil sump is positioned at an elevation lower than the elevation of the first oil sump. The oil drainage conduit effects oil drainage by gravity from the first oil sump to the second oil sump to prevent the level of oil collected in the first oil sump from exceeding the selected critical vertical level.

  • Patent number: 9982918
    Abstract: A heating medium supplied to an evaporator is used to heat lubricant oil in a screw compressor before the screw compressor starts up, and no additional heater for heating the lubricant oil in the screw compressor is required. When the screw compressor operates, the heating medium discharged from the evaporator after the evaporator is heated by the heating medium, is used to cool the lubricant oil. The lubricant oil heated by a lubricant oil heat exchanger is directly injected into a motor and a screw rotor so that introduction of a liquid refrigerant into a compressive chamber is reduced when the screw compressor starts up later. The lubricant oil introduced into the motor is discharged toward a lubricant oil storage portion before the screw compressor starts up so that the liquid refrigerant is prevented in advance from being introduced into the screw rotor when the screw compressor starts up.

  • Patent number: 9212622
    Abstract: In a reciprocating engine piston, added equipment to renew the piston pin's oil film once per crankshaft rotation. The equipment is located between the connecting rod's small end and the underside of the piston crown. There is a plunger carrier with a plunger, and a saddle with a plunger bore. The saddle closely straddles the plunger carrier, maintaining the alignment of the arcuate plunger with the arcuate plunger bore, for a plunger stroke without friction. The small end's natural oscillation during crankshaft rotation powers the plunger's working cycle. There is an oil-filling stroke and a delivery stroke. The delivery is to the saddle's top, which is just below the piston crown. The oil pressure pushes upward on the piston crown, lifting the piston slightly and the piston pin bosses off the piston pin. In the small gap thus created, new oil can enter, recreating the oil film.

  • Patent number: 9188023
    Abstract: An oil supply system for a stationary turbomachine is provided. A safe operation of the turbomachine is enabled even at ambient temperatures of up to 60° C. for a plurality of hours in a novel connection arrangement of the components of the oil supply system, such as the oil tank, pump a, and heat exchanger, as well as the pipeline system, without one of the components having to be designed for a further increased operating temperature. The oil tank has two regions stacked horizontally one above the other for storing the oil. The two regions are largely or completely separated from each other by a separating element.

  • Patent number: 9022176
    Abstract: An active/passive system for managing the temperature of fluid within an automatic transmission includes two heat exchangers, an active solenoid valve and a passive wax motor valve. A first heat exchanger provides transmission fluid heating and receives a flow of engine coolant. A second heat exchanger provides transmission fluid cooling and is exposed to ambient air. The solenoid valve which is preferably driven by a signal from a transmission control module (TCM) and the wax motor valve cooperate to provide three states of operation: transmission fluid heating, that is, heat added, cooling, that is, heat removed and pass-through or bypass (without heating or cooling).

  • Publication number: 20150096839
    Abstract: An oil accumulator assembly may comprise a scavenge tube including an aperture defined by a break in the scavenge tube and/or an annular cylindrical structure concentrically situated about the scavenge tube. The aperture may be configured to receive oil flowing through the scavenge tube, and the annular cylindrical structure may be configured to accumulate oil flowing through the aperture. The oil accumulator assembly may further comprise a drainage outlet disposed in the annular cylindrical structure. Oil accumulated within the annular cylindrical structure may drain through the drainage outlet in response to an engine being shut down. The oil accumulated within the annular cylindrical structure may fill a portion of the scavenge tube situated within an engine fan case to prevent coking within the scavenge tube.

  • Patent number: 8978825
    Abstract: A dual-line pump unit for supplying lubricant includes a reservoir having an interior for holding lubricant. A first pump is provided for pumping lubricant from the reservoir through a first main line to a lubricant distribution system. A second pump is provided for pumping lubricant from the reservoir through a second main line to the lubricant distribution system. During a first stage of operation, the first pump operates to pump lubricant from the reservoir through the first main line to the lubricant distribution system and the second pump is idle, the second main line venting back to the reservoir via the second pump. During a second stage of operation, the second pump operates to pump lubricant from the reservoir through the second main line to the lubricant distribution system and the first pump is idle, the first main line venting back to the reservoir via the first pump.

  • Publication number: 20140326539
    Abstract: 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.
