Abstract: A system for cooling a storage area of a vehicle includes one or more eutectic plates (102) for cooling the storage area (101); a refrigeration system (103) configured to cool the one or more eutectic plates (102); an electrical system (106) configured to receive electrical power from a mains power supply and supply electrical power to the refrigeration system (103); a variable displacement hydraulic pump (113) having an input shaft for being driven by an engine (112) of the vehicle (100); and a generator (107) configured to receive hydraulic fluid from the hydraulic pump (113), generate electrical power in response thereto and supply the electrical power to the refrigeration system (103); the hydraulic pump (113) is configured to reduce the volume of hydraulic fluid that it supplies to the generator (107) for each rotation of the input shaft, as the rotational speed of the input shaft increases.

Abstract: Disclosed is a transportation refrigeration unit (TRU 104) for conditioning air in a cargo box (106), the TRU including a TRU controller (108) that is electronically connected to a truck engine controller (170), wherein when a delta between a cargo box temperature and a cargo box set point temperature is greater than a predetermined threshold, the TRU controller actuates the truck engine (168) when the truck engine is off, and conditions air in the cargo box to return the cargo box temperature to the set point temperature.

Abstract: A control system (300) for a transport engineless refrigeration unit (301), the control system including: a controller (302) for communication between a vehicle (307) and a plurality of vehicle devices, the controller comprising: a vehicle data connection (306) for transmitting data to and from a vehicle; a vehicle engine on/off connection (308) for triggering start-up of the vehicle engine; a plurality of device data connections (314), each device data connection transmits data to and from at least one device external to the controller; and a device power connection (313), the device power connection supplies power from the controller to at least one device external to the controller.

Abstract: A lubrication device for a power take off coupling for a prime mover, the lubrication device including: a lubrication device shaft having a first end for connecting to an output shaft of the prime mover and a second end for connecting to an input shaft for receiving power from the output shaft; a lubricant chamber surrounding at least part of the lubrication device shaft between the first end and the second end; and a housing enclosing the lubrication device shaft and the lubricant chamber; wherein the lubrication device shaft includes a plurality of internal lubricant passages for conveying lubricant from the lubricant chamber to the first end and the second end of the lubrication device shaft, with the internal lubricant passages comprising fluid passages extending along the axial length of the lubrication device shaft as well as fluid passages extending radially to outer surfaces of the lubrication device shaft.

Abstract: A transport refrigeration system including: a transportation refrigeration unit configured to provide conditioned air to a refrigerated cargo space; an energy storage device configured to store DC electrical energy to power the transportation refrigeration unit; and a DC-to-AC variable invertor electrically connecting the energy storage device to the transportation refrigeration unit, the DC-to-AC variable invertor being configured to convert the DC electrical energy from the energy storage device to AC electrical energy in a variable continuous energy output to power the transportation refrigeration unit.
