  • Publication number: 20150354879
    Abstract: A method to reduce/prevent liquid refrigerant flooding in the compressor is disclosed herein. The method may include closing down the ETV when there is a risk of compressor flooding. The method may include closing down the ETV to a desired value when there is a risk of the compressor flooding. A failure to provide the superheated refrigerant vapor in a desired superheat temperature by the compressor may indicate a risk of the compressor being flooded by liquid refrigerant. The method may include measuring a refrigerant discharge temperature of the compressor, and closing down the ETV when a difference between the refrigerant discharge temperature of the compressor and a refrigerant saturate temperature is below a desired temperature threshold.

  • Publication number: 20150328953
    Abstract: Systems and methods are directed to controlling the amount of power supplied by an engine for a transport refrigeration system (TRS). An engine load is estimated and compared with a maximum allowable power supply from an engine. The engine load can be automatically adjusted according to results of the comparison. An automatic adjustment of the amount of power supplied by the engine is provided, to ensure that the engine is operating within a preset window of operation and compliant with emission legislation.

  • Patent number: 7849941
    Abstract: A universal linkage assembly for a power machine is disclosed. The universal linkage is adaptable for different control configurations or patterns. For example, in embodiments disclosed, the linkage assembly includes a first control interface connectable to one of a first or second joysticks to operate one of a left or right drive motor or other function and a second control interface connectable to either the first or second joystick to operate the other of the left or right drive motor or other function with separate joysticks or the same joystick depending upon the control pattern desired.

  • Publication number: 20100206882
    Abstract: A coolant tank for receiving a fluid from the cooling system of an internal combustion engine includes a pressurized tank having a pressurized reservoir configured to contain the fluid and an overflow tank integrated with the pressurized tank. The pressurized reservoir includes an inlet port configured to receive the fluid from the cooling system, an outlet port configured to direct the fluid from the pressurized reservoir to the cooling system, a fill neck in fluid communication with the pressurized reservoir, and a pressure cap removably coupled to the fill neck. The overflow tank includes an overflow reservoir maintained at atmospheric pressure and configured to receive overflow fluid from the pressurized reservoir when the liquid of the cooling system expands. At least a portion of the fill neck is positioned within the overflow reservoir.
