Abstract
A valve provided for the blocking or controlled establishment of a volume flow of a working fluid in a flow path of a technical device that transmits and/or stores energy, in particular in a control device for a hydraulic drive, an associated method of manufacture of the valve, and an apparatus with the valve. The valve includes first, second, and third valve openings, a moveable shut-off body moveable between an open-position and a close-position, a guide which guides the shut-off body between the open-position and the close position, and a retainer which exerts a retaining force on the shut-off body in the close-position. The guide has three guide parts. The first and third guide parts enclose the shut-off body and the second guide part includes a plurality of pins in a parallel orientation to the direction of movement of the shut-off body.
