Abstract
An unloader ring 20 has a plurality of unloader fingers 21 passing through intake channels 16 of the intake valve 5 arranged in the ring-shaped intake chamber 11 such that the unloader ring 20 is guided on the wall 24, 31 of the intake chamber 11, where it is arranged displaceably by means of the circumferential surface 23 of the unloader ring 20 on the outside radially or by the circumferential surface 30 of the unloader ring 20 on the inside radially. A radial step 25 is provided on the circumferential surface 23 of the unloader ring on the outside radially or on the circumferential surface 30 of the unloader ring 20 on the inside radially, and a control chamber 26 is formed between the wall 24, 31 of the intake chamber 11 and the radial step 25, this control chamber being connected to a control line 27 for supplying a control medium into the control chamber 26. A lower stop (32) for the unloader ring (20) is provided in the intake chamber (11), this stop being designed so that the unloader finger overhang (f) of the unloader ring finger (21) is smaller than the intake stroke (h) of the intake valve (5).
