Abstract: A valve assembly for regulating the flow of working fluid between a working chamber of a fluid working machine and a working fluid gallery comprises: a valve comprising a valve member and one or more cooperating valve seats; an actuator actuatable to apply a force to urge the valve member away from or towards the one or more valve seats; and a coupling between the actuator and the valve member. The coupling comprises a connector located at least partially within a tube. A connector void provided between at least a portion of the connector and the tube is in fluid communication with a working fluid gallery outlet.
