SINGLE MAIN TUBE TYPE CENTRALIZED LUBRICATING SYSTEM AND VEHICLE EQUIPPED WITH THE SYSTEM

摘要

PURPOSE: To ensure depressurization of a main tube no matter when a key switch is turned off, thereby avoiding leaving the main tube as the pressure remains inside, so that a load to the main tube or grease is lessened. ;CONSTITUTION: A controller 6, which controls a main pump element land a depressurizing valve 5, is provided with an initial, depressurization commanding means 7, which, when a power source is turned on by a key switch 8, switches the depressurizing valve 5 so that the main tube 3 becomes open to an oil tank 2. In addition, a power source circuit of the controller 6 is provided with a reelectrifying means 10, which reelectrifies the controller 6 from a car battery 9 for a certain period of time after the power source is shut off through the 'off' operation of the key switch 8, so that the initial, depressurization commanding means 7 is actuated. As a result, the pump 1 will not stop unless the main tube 3 is depressurized in advance.;COPYRIGHT: (C)1993,JPO&Japio
