Document Type and Number:
Japanese Patent JP2009505004
Kind Code:
A
Abstract:
The invention relates to a control valve unit (9) for a variation device of a hydrostatic piston engine. The control valve unit (9) comprises a valve housing (34), in which a valve element is disposed in a longitudinally displaceable manner. The valve element is adjustable from a neutral position in the direction of a first end position and an oppositely directed second end position. With increasing adjustment of the valve element a first or a second output port (35a, 35b) is increasingly connected to an input port (12). The respective other output port (35b, 35a) is at the same time increasingly connected to a relief line (13). The valve element comprises a first valve piston (32a) and a second valve piston (32b), which act upon one another via an elastic element (27).
