Abstract (en)

[origin: DE19827363A1] The piston store a cylinder (1) with an axially movable switching pushrod (25). When a set load pressure is reached in the cylinder oil cavity, the pushrod moves the piston (3) to operate a switching valve (23). The valve cuts off the flow of fluid to the oil cavity and is fitted so that it can be operated by the outer end of the pushrod, which passes out through the cylinder cap (39) via a seal.
