Control circuit for hydraulic cylinder - has manually operated pump feeding two cylinders in series via hoses

摘要

The hydraulic control circuit has a hydraulic cylinder with a piston fixed to a piston rod. The cylinder is supplied by hydraulic fluid from a manually operated pump. The pump is actuated by a lever (9). The discharge from the cylinder is joined to the chamber (16). The hoses (18) are joined to a second cylinder (21). The cylinder feeds a third hydraulic cylinder (19). The first cylinder is fixed by lugs (13) mounted to the free end of the hydraulic cylinder.
