Abstract (en)
[origin: EP2620657A2] The valve arrangement has a control valve (1), over which a regenerative connection (C2) and another connection (C1) of a load are provided. A regeneration valve is provided with only two switched positions, over which pressurizing agent from the regenerative connection is derivable in a tank (6). The regeneration valve is opened between the connections above a predetermined pressure difference and is closed at the rest of the time. A control slide (14) of the control valve has a common regeneration- and working position (a).
