Abstract

An actuator arrangement (1) for an inlet air valve of a compressor system of a mining machine, the actuator arrangement comprises a linear actuator (11) comprising a movable element (10), operatively connected via a lever mechanism (6, 7, 8, 9; 6, 7, 8, 9, 91, 92) to a shaft (4) of a closing element (3) of the inlet air valve. A linear movement of the movable element (10) of the linear actuator (11) is transmitted via the lever mechanism to a rotation movement of the shaft (4) of the closing element (3) of the inlet air valve, wherein a transmission ratio of the lever mechanism is configured to vary during a movement of the movable element (10) of the linear actuator (11).
