Abstract: A piston accumulator (10) comprises a pressure chamber (40) which is closed on one side by an axially shiftable piston (50) in order to change its volume depending on the axial position of the piston (50). A locking mechanism is provided for retaining the piston (50) in a second position different from a first position against a spring preload (190). The piston accumulator (10) further comprises an electromagnetic apparatus (80) having an armature (150) which is shifted upon axial shifting of the piston (50) from the first into the second position in its turn into an axial position in which a blocking element (175) of the locking mechanism is held by the armature (150) in a radial position so as to block a shift of the piston (50) back in the direction of its first position. For holding the blocking element (175) there is provided a separate interlocking member (170) which is fastened to the armature (150) and is made of a harder material than the armature (150).

Abstract: An accumulator for storing fluid that includes a shell that defines an interior volume of the accumulator. The shell includes at least one port for providing fluid to a fluid system. The accumulator also includes an accumulator shaft disposed in the interior volume and extending at least partially across the interior volume from a first interior surface of the shell along a longitudinal axis of the shell, e.g., a central axis. The accumulator includes a piston-plate disposed in the interior volume such that the piston-plate and a second interior surface of the shell define a chamber in the interior volume. The accumulator further includes a motor disposed in the interior volume. The accumulator is configured such that rotational movement of the motor translates to linear movement of the piston-plate along the accumulator shaft.
