| The invention relates to a rock drilling rig. The rock drilling rig (1) comprises a drilling unit (4) provided with hydraulically operated actuators such as an impact device (9), a rotation device (11) and a feed device (7). The impact device and the rotation device are connected to dedicated hydraulic circuits provided with dedicated supply and discharge lines and are controlled by means of dedicated control valves being on the a carrier (2) of the rock drilling rig. The feed device is connected to a distributed hydraulic system wherein several actuators are connected to a common hydraulic circuit (CHC) provided with one common supply line (15) and one common discharge line (16) and are controlled by several distributed valves. The distributed valve of the feed device is located at the drilling unit. | ||||||
