DEVICE FOR CONTROLLING THE CONNECTION TO BE DISPLACED TEMPORARY OF TWO UNIT WHICH CAN BE PRESSURIZED WITH PRESSURE MEDIUM WITH PRESSURE MEDIUM SOURCE

摘要

The present invention is a pressure medium source (pressure medium source) and the pressure to be be in unit between the connection to the formation for controlling the valve device (control valve arrangement) to contain, and the pressure medium (pressure medium) to a pressure to be be in two units to relates to a device for controlling the connection to be displaced in a pressure medium source and sequentially, the control valve device is a pilot control valve (pilot control valve; 19) controllable by the engine signal interacts with, and the pilot control valve, and the slide valve (sliding valve) to form that the main control valve (main control valve; 20) for containing, and wherein the main control valve is a pressure medium source and connectable entrance (entrance; 23) and the pressure to be be in units to the association that is 2 of exit (exit; 24, 25) a provided, and wherein the outlet of the main valve slider (main valve slider; 22) is separated from the inlet (23) and load relief and main valve slider (22) when in its intermediate position and the inlet being corresponding to the deflection (deflection) in the middle position can be connected to the shift 23, a control device that is linked to the main valve slider 22 (controller) is for biasing the main valve slider (22) from the intermediate position the pilot control valve 19 is activated when the control and the displacement device is disabled in the absence of engine signal (cylinder-piston unit; 27) and the centering device is permanently enabled (cylinder-piston unit; 33) includes the centering device may be penetrated by the displacement unit is activated, the main valve slider 22 may be moved to an intermediate position by a centering device when the displacement device is disabled. This is higher than stability. ; Two-stroke large diesel engine, the pressure medium control valve, the injection pump, the actuator
