Abstract

PURPOSE: To devise to prevent jumping phenomenon at the starting and speed- changing of a cylinder inexpensively by less number of parts in a discharge control valve with pressure compensation to be ussd for the speed control of the cylinder changeable in load.
CONSTITUTION: In this discharge control valve with pressure compensation, a three-position throttle valve 24 and an electromagnetic four-way valve 21 are provided between a pump 22 and an electromagnetic four-way vavle 23, and a tank port T2 of the valve 23 is connected with a tank through a pressure compensator 26. Here, in the above-written three-position throuttle valve 24, on the right side of a spool 8 arranged in the main body 7 to be freely slided, a pressure chamber 9 is provided to be connected to a passage 10, and when the spool 8 is moved to the left by a spring 11, equipped inside passages 12 and 13 are combined. Besides, on the left side, a pressure chamber 15 is provided to be connected to a passage 16, while an adjusting screw 17 is arranged to control the stroke of the spool 8, and a spring 19 is equipped in a chamber 20 to be adjusted by an adjusting screw 18.
