Hydraulic Reference

Connection to atmospheric pressure


Hydraulic Elements

  • Hydraulic Reference block


The Hydraulic Reference block represents a connection to atmospheric pressure. Hydraulic conserving ports of all the blocks that are referenced to atmosphere (for example, suction ports of hydraulic pumps, or return ports of valves, cylinders, pipelines, if they are considered directly connected to atmosphere) must be connected to a Hydraulic Reference block.


The block has one hydraulic conserving port.
