A printing system component, a tool for disassembling a printing system component, a printing system with a printing system component, and a method for disassembling a printing system component

摘要

The present invention relates to a printing system component (1) comprising a component body (3), a sealing plug (5) and a retaining ring (7). The component body (3) has a stepped bore (9). The stepped bore (9) has at least one step (11). The closure plug (5) has at least a first stop (13) and a second stop (17). The sealing plug (5) is designed to be inserted into the stepped bore (9) and to close the stepped bore (9) such that pressurized pressure medium can no longer escape from the stepped bore (9). The stepped bore (9) has a radially encircling securing groove (15) for receiving the securing ring (7), wherein the first stop (13) of the sealing stopper (5) together with the at least one step (11) of the stepped bore (9) and the second stop (17) of the sealing plug (5) together with the locking ring (7) embedded in the locking groove (15) limits the axial mobility of the closure plug (5) in the stepped bore (9). In this case, at least one access groove (21) for inserting a tool (30) is provided on the inner surface of the stepped bore (9), so that the locking ring (7) with the aid of the tool (30) from the securing groove (15) is removable. Furthermore, the present invention relates to a suitably designed tool (30), a printing system equipped with such a printing system component (1), and a corresponding method for dismantling the securing ring (7).
