20090114183 | Transmission Thermostat Device - A transmission thermostat device includes a body having first and second input ports and first and second output ports. A first fluid path extends between the first input port and the first output port. A second fluid path extends between the second input port and the second output port. A bypass port is disposed between the first fluid path and the second fluid path. A temperature sensing mechanism is disposed within the housing. The temperature sensing mechanism element is operative in a first mode to close the bypass port and in a second mode to open the bypass port. The temperature sensing mechanism includes a bimetal element responsive to a change in temperature. | 05-07-2009 |
20100193594 | ELECTRONIC THERMOSTAT - A thermostat includes a housing defining a fluid path therethrough. The thermostat further includes a valve plate for selectively sealing an opening in the fluid path for opening and closing the fluid path. The valve plate is mounted within the fluid path for rotation about a pivot axis extending generally perpendicular to the flow of fluid through the housing. The valve plate is configured and disposed within the fluid path such that fluid pressure against a first portion of the valve plate creates a first torque and fluid pressure against a second portion of the valve plate creates a second torque. The first and second torques substantially cancel each other out such that a net torque generated by the fluid pressure on the valve plate is neglible. | 08-05-2010 |
20100276613 | THERMOSTATIC DEVICE AND RELATED METHOD - A thermostatic device for selectively opening and closing one of more apertures used for controlling the flow of a coolant fluid includes a housing, at least one fixed element and at least one moveable element. The at least one fixed element is fixedly interconnected to the housing. The at least one moveable is moveably connected to the housing. A fluid path passes through the fixed element and the moveable element. The fluid path is opened and closed in response to movement of the moveable element relative to the fixed element such that when the moveable element is in a first position the fluid path is closed and when the moveable element is in a second position the fluid path is open. A temperature responsive bi-metal element is coupled to the moveable element for moving the moveable element between the first position and the second position. | 11-04-2010 |
20110067853 | FLUID COOLING DEVICE FOR A MOTOR VEHICLE - A fluid cooling device for a motor vehicle includes a fluid inlet tank and a fluid outlet tank. A plurality of heat transfer tubes provide constant fluid communication between the inlet tank and the outlet tank. A bypass arrangement selectively provides additional fluid communication between the fluid inlet tank and the fluid outlet tank. A bi-metallic valve is moveable from a first position to a second position in response to an increase in temperature of the fluid such that the valve member closes the at least one bypass tube to preclude additional fluid communication between the fluid inlet tank and the fluid outlet tank when the valve member is in the second position and the valve member opens the bypass tube to provide additional fluid communication between the inlet tank and the outlet tank in the first position. | 03-24-2011 |
20110210179 | INTERNAL TRANSMISSION THERMOSTAT - An internal thermostat for an automatic transmission of a motor vehicle includes a thermostat housing, a rotary valve and a bimetallic, temperature sensitive element. The thermostat housing is attached to an internal flow aperture of the transmission to be controlled. The rotary valve is moveable between an open position and a closed position in response to a temperature of oil, thereby controlling oil flow through the internal flow aperture of the transmission. The bimetallic temperature-sensitive element is attached to the rotary valve and operative to control an angular position of the valve as a function of the temperature of the surrounding oil. The bimetallic, temperature-sensitive element may be shaped like a coil. Alternatively, the bimetallic, temperature-sensitive element may be shaped like a substantially linear strip. | 09-01-2011 |
20110259548 | HEAT EXCHANGER AND RELATED METHOD OF MANUFACTURE - A heat exchanger for an internal combustion engine of a motor include first and second radiator tanks and a plurality of radiator tubes extending between the first and second radiator tanks. The first radiator tank includes a plurality of walls. Brazed joints are between the plurality of walls to make the first radiator tank liquid tight. Brazed joints are also between the plurality of radiator tubes and the first and second radiator tanks. An oil-cooling structure is disposed inside the first radiator tank. The brazed joints between the plurality of walls and between the plurality of radiator tubes and the first and second radiator tanks are simultaneously formed. | 10-27-2011 |
20120055657 | COMPACT HEAT EXCHANGER - A heat exchanger includes at least two tanks containing a medium to be temperature treated and a plurality of heat exchange tubes extending between the at least two tanks. The heat exchange tubes have exterior surface areas at least partially defining a heat exchange area. A set of cooling fins is located between the heat exchange tubes of the plurality of heat exchange tubes to increase the heat exchange area. The fins are configured to define a plurality of non-straight line paths for the flow of air across the heat exchanger. The non-straight line paths force the flow of air across the heat exchange to change direction and cause impingement of the air onto the fins and tubes as well as turbulence for increasing heat transfer performance. | 03-08-2012 |
20120111955 | THERMOSTATIC CONTROL DEVICE - A transmission thermostat adapted to control the flow of automatic transmission fluid between a transmission and a transmission oil cooler including a temperature-sensitive mechanism. The temperature-sensitive mechanism includes at lease one bimetallic coil. | 05-10-2012 |
