Abstract (en)
[origin: DE102005029821A1] The valve has two slides (4, 5) which are spring-loaded towards the center of a bore (42). The slides share a common control system which allows pressure to be applied simultaneously to their front surfaces (44, 46) and to their rear surfaces (60, 62), which are smaller in area. An independent claim is included for LS-control systems for hydraulic fluid which contain the valve.
