  • Patent number: 10208850
    Abstract: A transmission includes a torque converter, an output shaft, rotatable gearing components, a case, and a pan secured to the case. The case defines a torque converter housing for receiving the torque converter, an output shaft housing for receiving the output shaft, and a central barrel extending between the torque converter housing and the output shaft housing for receiving the rotatable gearing components. The case further defines a first hole and a second hole through a bottom wall of the central barrel and a tapering channel extending longitudinally along the central barrel from the first hole to the second hole. The pan defines a fluid reservoir disposed below the first and second holes to receive gravity-fed fluid from the tapering channel through the first and second holes.

  • Patent number: 8376088
    Abstract: A twin lubrication oil tank filling system with a single oil fill port that prevents overfilling of both a primary oil tank and a secondary oil with a gravity fill system by directing oil primarily into the secondary oil tank by means of a special oil diverter, a float valve for the secondary oil tank that closes when the oil level in the secondary tank reaches a full level to cause additional oil flow to pour into the primary oil tank and a float valve for the primary oil tank that closes when the oil level in the primary tank reaches a full level.

  • Publication number: 20080169030
    Abstract: A valve assembly for selectively and variably communicating fluid between an auxiliary sump volume and a main sump volume, each defined by a transmission, is provided. The valve assembly includes a float member operatively connected to a valve member and disposed within the main sump volume of the transmission. The valve member is movable between an open position and a closed position. The float member is configured to be buoyed by the fluid within the main sump volume to move the valve member from the open position toward the closed position thereby variably restricting the flow of the fluid between the auxiliary sump volume and the main sump volume as the amount of the fluid within the main sump volume increases. A transmission incorporating the valve assembly is also disclosed.

  • Patent number: 7143867
    Abstract: An oil level monitoring and replenishment system for use with an internal combustion engine having an oil sump. The system as a sensor which continuously measures the sump level in the reservoir for holding a quantity of oil to be used in replenishment of the sump. A sensor monitors the oil level in the sump and causes replenishment from the reservoir when needed. The reservoir has warning circuit interactive with a reservoir sensor to signal from the reservoir has reached a lower level of oil and requires the filling. The sensor also provides means to signal when the reservoir has been filled to the desired level to prevent overfilling.

  • Patent number: 6988590
    Abstract: A modular oil delivery system has a mount with at least one passage, a flange and a body depending from the flange. A mounting bracket is carried by the mount to support an oil pump having an oil outlet in fluid communication with at least one passage in the mount. A float arm is pivotally supported relative to the mounting bracket and is constructed and arranged to be responsive to the level of the oil in the reservoir. An oil pressure sensor is supported by either the mounting bracket, the body, or the flange. The oil pressure sensor is in fluid communication with at least one passage in the mount and with the oil outlet of the oil pump to monitor the pressure of oil discharged from the oil pump.
