PURPOSE:To always carry out proper supply of oil with respect to engine load characteristics, by driving a pulse motor with a pulse signal according to an engine operational condition, and adjusting a quantity of oil to be supplied to a cylinder according to an operational amount of the pulse motor. CONSTITUTION:An engine load signal is converted to a pulse signal by a pulse generator 103, and is fed to a pulse motor 102. Then, the pulse motor 102 is rotated by a predetermined angle, and accordingly, a flow controller 104 is operated. Then, a quantity of hydraulic oil to be fed to a hydraulic motor 7 is adjusted to adjust a quantity of the oil to be fed to a cylinder. Thus, it is possible to always supply a proper quantity of oil to the cylinder with respect to engine load characteristics. |
