A device for filling or discharging a liquid comprises: an elongated body (9), a coaxial closure sleeve (4) mounted axially on the main sleeve (1), wherein the main sleeve (1) is slidable relative to the closure sleeve (4) and the body (9) and comprises an outlet end on its side remote from the body (9) and an inlet end on the side closer to the body (9), facing the liquid inlet, at the inlet side the main sleeve (1) has lateral surface outflow openings (la), a push-button (2) for actuating the liquid outflow located at the outflow end of the device, located on the main sleeve (1) at its outlet end side, which said push-button (2) is non-rotatably mounted thereon, and between the main sleeve (1) and the closure sleeve (4) a sealing diaphragm (3), as well as the helical spring (5) of the push-button (2) are arranged. The liquid flows by axially displacing the push-button member (2). |
