HYDRAULIC VALVE OF COMBINE HARVESTER

摘要

PROBLEM TO BE SOLVED: To provide a hydraulic valve simplifying the connection of a hydraulic valve to each hydraulic actuator and efficiently carrying out inspection and maintenance operation thereof in a combine harvester equipped with the hydraulic valve arranged in a step frame of an operation step. SOLUTION: Each discharge port of the hydraulic valve is installed on the side of a mounting surface of the hydraulic valve on the step frame and an opening is provided in a mounting side plate of the step frame in a position corresponding to the discharge port. The hydraulic valve is connected through the opening to each hydraulic actuator with a hydraulic pipe. An IN port for introducing a hydraulic fluid from a gear pump into the hydraulic valve and an OUT port for discharging the hydraulic fluid from the hydraulic valve are installed on the front side of the hydraulic valve, respectively. The front plate of the step frame is composed so as to be demountable. COPYRIGHT: (C)2005,JPO&NCIPI
