    Abstract: A flushing element, rock drilling machine and method of providing a flushing space around a shank adapter of a rock drilling machine. The flushing element surrounds the shank adapter passing through it. The flushing element has a feed opening for feeding flushing agent to the flushing space and at least two sealing housings for flushing sealings and wherein the flushing sealings are on opposite axial sides of the flushing space. Furthermore, the flushing element has split configuration whereby it is mountable and demountable in radial direction.

    Abstract: A breaking device includes a frame, an impact device having a pressure chamber with a rear pressure chamber and a front pressure chamber. The breaking device further includes a first low pressure port at the rear pressure chamber, a first low pressure channel and a first low pressure accumulator connected to the first low pressure channel. The breaking device further includes a second low pressure port at the rear pressure chamber substantially opposite to the first low pressure port, second low pressure channel and a second low pressure accumulator connected to the second low pressure channel. The first low pressure accumulator and the second low pressure accumulator are arranged at the outer circumference of the frame of the breaking device at different positions in the axial direction of the breaking device.

    Abstract: An arrangement in a rock drilling machine and to a method of mounting the same, the rock drilling machine including a gear module and a percussion module, which are arranged on a same axial line. The modules are pressed towards each other by several first connecting devices and several second connecting devices. The connecting devices generate first axial connecting forces and second axial connecting forces, which receive axial operational forces of the rock drilling machine. The second connecting devices also fasten the rock drilling machine to a carriage provided with support surfaces.

    Abstract: A hydraulic system, rock drilling rig, and method for limiting output performance of a hydraulic drilling actuator temporarily under execution of a safety function feature of a hydraulic system is provided. The output performance is limited by limiting produced hydraulic fluid flow in a hydraulic circuit of the hydraulic drilling actuator, whereby a restricted magnitude of the fluid flow is produced at a hydraulic pump. This way a restricted operation mode is enabled and is controlled by a control unit.
