CLAIMS : -

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

2. A self-inking roller according to claim 1, further characterized in that said body (6) includes a substantially cylindrically shaped section and further characterized by a tubular spindle mounting member (2) having a bore (4) therein for receiving the mounting spindle said tubular member (2) being coaxial with said cylindrically shaped section of said main body

(6) and operatively connected thereto for rotation therewith.

3. A self-inking roller according to claim 2, further characterized by opposed end caps (30) (36) at respective ends of said main body (6) .

4. A self-inking roller according to claim 3, further characterized by coupling means (12) (65) operatively connecting said valve actuating means (36) to said valve element (20) (63) .

5. A self-inking roller according to claim 4 , characterized by said annular valve seat (20) being disposed near one end of said main body (6) and said coupling means (12) being a tubular member arranged coaxially with said spindle mounting member (2) and said main body (6) arranged for axial movement
relative to said main body (6) to cause relative movement between said valve element (20) and said valve seat (22) .

6. A self-inking roller according to claim 5, further characterized in that said actuating means 36 comprises one of said end caps mounted for limited axial movement relative to said main body by rotation thereof relative to said spindle mounting member (2) .

7. A self-inking roller according to claim 6, further characterized in that said flow path includes a circumferential distribution channel (24) at one end of said main body adjacent said valve.

8. A self-inking roller according to claim 7, further characterized in that said distribution path includes a plurality of openings (26) in the wall of said main body adjacent said distribution channel (24) permitting ink to flow to the external surface of said main body.

9. A self-inking roller according to claim 4, characterized in that said coupling means comprises cam element (65) mounted between the spindle mounting member (2) and the valve element (63) .
