Abstract
A piston accumulator can be used for hydraulically actuating the discharge unit in non-automotive bulk commodity vehicles. The accumulator cylinder has a tappet which can be axially displaced within the cylinder. When a defined load pressure is reached in the oil chamber of the cylinder, the tappet can be displaced by a piston to actuate a control valve. The valve serves as shut-off device for the loading fluid stream flowing to the oil chamber and is positioned as a detachable module on the exterior face of cylinder cover in such a way that it can be actuated by the outer end of the tappet. The tappet is guided towards the outside by passing in a sealed manner through the cylinder cover.
