摘要：Pressure gain compensation for a single-stage servovalve of the jet pipe type.The pressure gain compensation is provided by a separate reciprocally mounted spool(36) having a feedback wire (46) connected between the spool (36) and the ejector jet(12). The spool has a differential pressure applied across the ends thereof from the

receptors (14,16) disposed opposed the ejector jet. Movement of the spool applies aforce feedback to the ejector jet which is proportional to the pressure differential acrossthe receptors and is opposite the force applied to the ejector by the torque motor (20)to thereby compensate for pressure gain.
