摘要: A hydraulic leveling system for a vehicle has at least one set of hydraulic jacks that are extended by applying hydraulic pump pressure to an extend side of the jacks and are retracted by relieving hydraulic pressure from the extend side and applying hydraulic pressure to a retract side of the jacks. A pressure sensor has a pressure set point that when it is exceeded the system generates a signal indicating retraction of the jacks. The system operates so that after the pressure sensor set point is exceeded, the system turns off the pump and continues to hold open a valve that applies pressure from the pump to the retract side of the jacks for a period of time and that permits flow to continue from the extend side of the jacks to tank. After such period of time the system once again checks whether the pressure sensor is still activated and if it is not still activated, the system turns the pump back on and continues to retract the jacks.

摘要: A hydro-pneumatic system has an air powered motor driving a hydraulic pump with a pressure limiting valve that turns off air flow to the air motor when a hydraulic pressure output by the pump at a sense port of the valve reaches a certain limit. A valve element of the valve has spring, hydraulic and pneumatic sections, with an unbalanced area of the hydraulic section in a sealed pressure chamber of a cartridge that is part of the valve housing. The pneumatic section extends out one end of the cartridge to fill a bore between the air inlet and outlet ports when the pneumatic section is extended, and allow air to pass when it is retracted.

摘要: An apparatus for balancing a plurality of cells in a battery includes common bus having a connector for connecting to a common bus of another battery. Each of plurality of balancing circuits has a bidirectional voltage converter connected to a given cell of the plurality of cells and a linear current regulator arrangement controls the magnitude of current flow between the bidirectional voltage converter. A controller is connected to the common bus and the plurality of cells and selectively operatives the plurality of balancing circuits to transfer energy between the plurality of cells and the common bus to balance the states of charge of the cells. The balancing circuits are operated in response to actual states of charge of the cells, an average state of charge, a desired voltage level for the common bus, and an actual voltage level on the common bus.
