A self-inking roller comprises a main body (6) mounted for rotati on on a spindle, a cylindrical porous member (10) disposed on an external surface of the main body (6) with an ink reservoir within said main body (6). An ink distribution path (24, 26, 28) (61, 69, 70) is provided which enables ink to flow from the reservoir to the porous member (10). The ink roller further includes valve means (20, 22) (61, 63) comprising an annular valve seat (22) (61) on the main body (6) and an annular valve element (20) (63). Valve actuating means (36) is provided for moving the valve element (20) (63) relative to the valve seat (22) (61) for controlling the ink flow in the ink distribution path (24, 26, 28) (61, 69, 70). |
