double-acting

Pushes and pulls

Double-acting describes a mechanism that works in both directions of its stroke.

A double-acting cylinder pushes and pulls; a double-acting door swings both ways.

In baking, double-acting baking powder reacts twice—first when wet, then when heated—giving more reliable rise than single-acting versions.
