Abstract

PURPOSE: To smooth the functioning of a cylinder by a method wherein the quantity of sliding of a main spool is controlled in response to applying currents, and directions are controlled and flow rate is proportionally controlled, in an electromagnetic proportional throttle change-over valve used for the fluid controller.
CONSTITUTION: The fluid controller is provided with a two stage type electromagnetic proportional throttle change-over valve 10, a single rod cylinder 50 and a sequence valve 60. The quantity of sliding of the main spool of a main valve 30 is controlled in response to the currents applied to an electromagnetic pilot valve 20, opening to each port P, A, B, T is adjusted, and flow rate is proportionally controlled. When oil discharged from a port 50a at the rod side exceeds the setting pressure of the sequence valve 60, the oil is fed to a port 50b at the head side through the sequence valve 60, a pressure line 71, the change-over valve 10 and a load line. Thus, the speed of extension of the single rod cylinder 50 can be increased.
