Abstract

PURPOSE: To facilitate manipulation, by fitting a check valve to the fixed side of a hydraulic stationary cylinder which is connected in parallel with a hydraulic working cylinder to a reversing valve.
CONSTITUTION: A hydraulic system of a hydraulic staionary cylinder 17 for a boom 2 which is connected to a stick 5 with a pivoted bucket 6 is composed of a hydraulic pump 21, oil tank 22, port 3 position reversing valve 23 for controlling 4 a hydraulic working cylinder 9 and a check valve 24 equipped with serial variable throttle valves 25. As the reversing valve 23 is switched for pressurizing the tail A of the cylinder 9 and the throttle valve 25 is opened full, the cylinder 17 turns open for the oil tank 22 to unlock the boom 2. As the reversing valve 23 is switched for pressurizing the rod B of the cylinder 9 and the throttle valve 24 is closed tight, pressure oil flows from the check valve 24 into the cylinder 17 to fix the boom 2.
