F15B11/161 - CPC Classification

Classification description:

Servomotor systems without provision for follow-up action; Circuits therefor with two or more servomotors with sensing of servomotor demand or load

Sub-classes:

F15B11/162 » {for giving priority to particular servomotors or users } 105
F15B11/163 » {for sharing the pump output equally amongst users or groups of users, e.g. using anti-saturation, pressure compensation} 81
F15B11/165 » {for adjusting the pump output or bypass in response to demand} 224
F15B11/166 » {Controlling a pilot pressure in response to the load, i.e. supply to at least one user is regulated by adjusting either the system pilot pressure or one or more of the individual pilot command pressures} 47
F15B11/167 » {using pilot pressure to sense the demand} 23
F15B11/168 » {with an isolator valve (duplicating valve), i.e. at least one load sense [LS] pressure is derived from a work port load sense pressure but is not a work port pressure itself} 13
