nonreciprocating
Lacking back-and-forth motion
Nonreciprocating describes something that doesn't move back and forth in a repeated cycle.
The term appears most often in mechanical contexts, distinguishing engines or pumps that use rotary motion from those with pistons: a nonreciprocating turbine.
It can also describe relationships or gestures that aren't mutual: nonreciprocating affection.
