Abstract
PURPOSE: To simplify a construction of lubricating oil supply for the device in every part of the work vehicle, by making the charge pump of drive gear to be combined in use as the lubricating oil feed pump for other devices.
CONSTITUTION: The lubricating oil feeder A, in which a main lubricating oil flow path c for the oil supply subject B of each part device 11W15 is connected to a charge pump delivery flow path a, with a manually operable on-off valve V and a variable throttle valve V1 intermediately installed in this lubricating oil flow path c, is made capable of feeding a supplementary operating fluid for a drive gear 7 to the oil supply subject B as the lubricating oil as necessary. And the oil feeder A is provided with an electrically operated liquid level detector 18 in an operating oil tank T, as well as with an electrically operating unit 19, that locks a valve opening operation, in the on-off valve V, and with a mechanism 21, that automatically suppresses a feed of the lubricating oil by a charge pump P1 when the liquid is below the set level as shown by an electrical linkage between the both of the above 18, 19 through an indicator lamp 20.
