HYDRAULIC CUTTER Russian patent published in 1996 - IPC

FIELD: agricultural engineering. SUBSTANCE: device has multiplicator whose high-pressure spaces communicate with nozzle through high-pressure lines and system of check valves and low pressure space communicates with hydraulic drive. Receiver is installed before nozzle. Each connection unit of high-pressure system has drain hole to which liquid leakage indicator is connected. Liquid leakage indicator has leak collecting space with inorganic acid salt placed in bottom portion. Cathode and anode are placed above salt level. Indicator is electrically connected with cutter control. EFFECT: increased efficiency of hydraulic cutting owing to improved reliability of hydraulic cutter. 2 cl, 3 dwg
