DEVICE FOR OPENING AND CLOSING A CLOSURE CAP |
摘要 |
The invention concerns a device for opening and closing a closure cap (16) fitted over a cleaning aperture (10) in the floor of the discharge container (12) of a pump (14) for thick-bodies fluids. The cap (16) is linked to a hydraulic drive unit (20) and can be swung out hydraulically, when a control valve (48) is actuated, into the open position in which the discharge outlet is left open. The cap (16) is swung back into the closed position by means of a hand-operated lever (23), the hydraulic drive unit (20) being returned at the same time to its initial position.
