.~ Having plural energy input means, pumps or diverse pump outlets
DEFINITION
Classification: 60/486
(under subclass 325) Apparatus in which (1) there are plural pressure sources, (2) in which the pressure source includes separately operable pump means; or (3) a pump means driven by separately operable energy input devices.
SEE OR SEARCH THIS CLASS, SUBCLASS:
375, for correlated power input pumps and/or pressurized fluid cyclically operated in driving a reciprocating stroke device.
386, for a power boosted manual pump system.
397, for a motor operated by the intake manifold of an internal combustion engine with a means for furnishing extra energy to the motor.
400, for a system having selective or simultaneous manual or power energy inputs.
405, for a safety system in which a second motive fluid supply means takes the load responsive to the failure of a first supply means.
413, for a system with means for controllable feeding stored energy to the motor.
419, for a system in which motive fluid in the system is pressurized by a pump driven by the motive fluid of the system.
421, for a system with an automatic control including plural motors and plural pumps or motive fluid sources with relationships selected by a multiway valve.
428, for a system of separately operable power input pumps, pump cylinders or pressure fluid sources that has automatic control means.
444, for a system including a nonpower pump supplying control pressure to a displacement adjusting servo-motor.
447, for a system including a run-power pump supplying pressure proportional to spread to a servo-motor controlling the displacement of a power pump or output motor.
464, for an automatically controlled motive fluid replenishing arrangement for a recirculating power pump and motor loop.
