Flushing circuit

Abstract

Abstract PURPOSE: To easily and accurately conduct flushing by a system wherein a closed circuit is connected with relief valves and a tank provided with operating means sequentially and with check valves for self-supply in parallel to the relief valves. CONSTITUTION: A flushing circuit 25 is connected to a closed circuit 5, and in the flushing circuit 25, oil exhaust pipe lines 26, 27 connected with both drip-oil pipe lines 3, 4 are connected to a mainfold pipe line 30 through relief valves 28, 29 and then, communicated to a tank 18. In the meanwhile, check valves 31, 32 for self- supply are connected with supply pipes 33, 34 inparallel to the relief valves 28, 29 and allow oil to be circulated to only the closed circuit 5. The relief valves 28, 29 are provided with operation levers 35, 36 to be suitably opened and closed by manual operation. COPYRIGHT: (C)1981,JPO&Japio
