Hydraulic control apparatus 17 for a vehicle suspension piston actuator 502 comprises; a first gallery (e.g. pipes, channels) G1 couplable to an actuator chamber C1; a second gallery G2 couplable to an actuator chamber C2; a third gallery G3 connected to galleries G1, G2 by valves X1, X3. The valve X1 is biased closed and permits flow from gallery G3 to gallery G1. Valve X3 permits air evacuation from gallery G3 to gallery G1 and is either movable to a closed position under a pressure drop; or controllable to permit air evacuation during filling, or closed to prevent hydraulic flow from gallery G1 to gallery G3.
