20090294343 | Suction Filter for Automatic Transmission Fluid - An assembly for filtering contaminants from automatic transmission fluid includes a housing including a first inlet and a second inlet, through which fluid enters the housing, and an outlet, through which fluid exits the housing; a first media filter located within the housing in a first fluid flow path between the first inlet and the outlet; and a second media filter located within the housing in a second fluid flow path between the second inlet and the outlet. | 12-03-2009 |
20120324873 | AUTOMATIC TRANSMISSION HYDRAULIC ACCUMULATOR - A hydraulic accumulator system for providing pressurized oil to a transmission in a vehicle. The system includes a transmission oil storage chamber to store oil at a predetermined level; and a hydraulic accumulator mounted in the oil storage chamber and including an accumulator piston mounted below the level of oil, separating an accumulator oil area from a remainder of the oil storage area and movable to increase and decrease the oil in the accumulator oil area, and a spring biasing the piston toward the accumulator oil area. The system also has a hydraulic assembly including a first oil passage for removing the oil from the remainder of the oil storage area, a second oil passage for directing oil into and out of the accumulator oil area below the predetermined oil level and a hydraulic circuit directing the oil from the first oil passage into the second oil passage. | 12-27-2012 |
20130017112 | CONTROL CIRCUIT FOR TRANSMISSION VARIABLE DISPLACEMENT PUMP WITH IMPROVED EFFICIENCY - The present disclosure relates to a control circuit for a variable displacement pump in a vehicle transmission, including: a regulator valve configured to regulate displacement control fluid to the variable displacement pump; and a response limiter in communication with the regulator valve, configured to mitigate pressure oscillations in the control circuit. | 01-17-2013 |
20140028022 | HYDRAULIC SUCTION LINE - A pump suction line assembly includes a sump including a wall formed with a bore and a seat, a tube including an inlet, an outlet, a length connecting the outlet and inlet, and a flange contacting the seat, a housing, a seal fitted in the bore and contacting the flange and the housing, and fasteners that compress the seal, secure the tube to the wall, and secure the sump to the housing. | 01-30-2014 |
20140076795 | SUCTION FILTER MEDIA OVERMOLDED INTEGRALLY WITH TRAY - A filter assembly includes a housing including a first cover and a second cover, a grid located in the housing including interconnected ribs and strips, and filter media integral with the grid, including a peripheral width located between the covers. | 03-20-2014 |
20140161641 | Accumulator for Maintaining Hydraulic Pressure Following an Engine Restart - A system for pressurizing transmission control elements includes an accumulator for containing pressurized fluid, first and second check valves, a booster valve supplied with accumulator pressure, and an actuator that causes the booster valve to open a fluidic connection between the accumulator and the control elements through the check valves in response to an engine restart signal | 06-12-2014 |
20140216693 | ELECTRIC VEHICLE THERMAL MANAGEMENT AND FILTRATION SYSTEM - A thermal management system for an electric vehicle is provided. The thermal management system includes a thermal circuit for regulating a battery temperature. A filter is located upstream of the battery for filtering liquid coolant. The thermal management system also includes a second thermal circuit in fluid communication with the battery thermal circuit. The second thermal circuit provides thermal control to a vehicle system other than the battery. The battery thermal circuit includes a plurality of battery cells. Pluralities of heat exchanger fins are located between each of the battery cells to provide the coolant to regulate the battery temperature. The filter has a filtration transfer function based on a filter characteristic of the fins. | 08-07-2014 |
20140311577 | SELF REPLENISHING ACCUMULATOR - An accumulator includes a cylinder for containing a working fluid and a first volume of pressurized gas, the gas and fluid being separated by a displaceable piston and a first seal contacting the piston and the cylinder, a reservoir carried on the piston for containing a second volume of pressurized gas, and a device that permits gas flow from the second volume into the first volume. | 10-23-2014 |
