A pump circle crossed by a diagonal arrow.
Also known as: Variable pump symbol, Adjustable pump symbol
In ISO 1219 fluid power diagrams a diagonal arrow drawn through a pump circle denotes a variable displacement pump: one whose output volume per revolution can be adjusted.
Denotes a pump whose displacement can be varied, the diagonal arrow being the standard's general mark for adjustability.
Contexts: Technical drawing
Uses the same diagonal arrow that marks any adjustable component in the notation, so the mark means adjustable wherever it appears rather than meaning variable pump specifically.
Contexts: Technical drawing
A pump circle with a long diagonal arrow drawn across it from lower left to upper right, extending beyond the circle at both ends.
