Abstract
PURPOSE:To contrive stabilization of controllability in such a way that a choke throttle is interposed in the channel to transfer pilot oil pressure to a main valve, and pulsation of oil pressure is effectively alleviated. CONSTITUTION:Supposing that a pilot oil pressure is transferred through a choke throttle 21 to the control chamber 19 or a main valve 5, when it passes through the choke throttle 21, the pilot oil pressure is pulsated in response to the frequency of an electromagnetic solenoid 2. In the meantime, when it passes through the choke throttle 21, the pulsation constituent is damped, and the pulsation is absorbed to the extent of almost no actual damage at the time of its propagation to the control chamber 19. Controllability will be stabilized because the piston part side 20 is pushed in response to the pilot oil pressure, and controllable oil pressure in the supplying path 23 is controlled.
