Document Type and Number:
Japanese Patent JP2004506852
Kind Code:
A
Abstract:
The invention relates to a valve that comprises at least one pump connection (10), one tank connection (14) and one consumer connection (18), and a valve piston (22) that is displaced within the valve box (12). Said valve piston separates the pump connection (10) from the tank connection (14) in at least one blocked position and interacts with an energy accumulator (24). A fluid stream that flows between the consumer connection (18) and the tank connection (14) is controlled by means of a control device (26). The control device (26) is configured as a fluid stream control that is integrated in the valve piston (22) and that allows, contrary to known valves which use a diaphragm construction, reduction, by a constant value, of the volume flow to the consumer in a load-independent manner, thereby allowing for a proportional load-independent control.
