Power cylinder distributor block - has differential piston controlled by three identical integral flow control valves with equalising operation

摘要

The distributor block is used to control a set of power cylinders having different piston areas. The valve belonging to the larger piston area can be adjusted optionally to the piston area of the power cylinder connected to it, without influencing the operation of the other valves built into the block in module fashion. Each power cylinder is controlled by four two-way valves (PA, PB, AT, BT). The valves (PA1, 2, 3) pressurise the load of the piston areas (A) and the valves (PB1, 2, 3) load the piston areas (B). A pump (12) is connected to channels (13) in the block. The fluid displaced from the cylinders (1, 2, 3) flows through channels (14), distributing valves (AT1, 2, 3) and (BT1, 2, 3) into a tank (15). The distributing valves of each cylinder side are interconnected by distributing elements (16) fitted in lateral channels.
