Abstract

PURPOSE: To eliminate damage or danger of a double cylinder type hydraulic piston, by hydraulically controlling a pilot valve through sub-cylinders of the double cylinders.
CONSTITUTION: Double type cylinders 21, 21a have their sub-cylinders 24, 24a which are connected with a pilot chamber of a pilot valve 26 through passages 36, 37 and the pilot valve 26 is controlled by fluid pressure from both sub-cylinders 24, 24a. Since the pilot chamber is kept under constant pressure without being influenced by the hydraulic pressure thus fed, the pilot valve 26 can be controlled only by the differential pressure required for transferring the spool, which contributes to eliminate damage or danger of the device.
