Abstract

A hydropneumatic accumulator has a separator piston, movable in the chamber of a housing. A switch member is attached to the separator piston by a support for simultaneous movement. Sensors can be influenced by the switch member position. The switch member is surrounded by a tube member which supports the sensors and is attached to the housing. A filling attachment is provided on the tube member. A filling conduit extends within the tube member and adjacent the support to simplify the configuration of the hydropneumatic accumulator.
