Abstract: A valve device has a valve housing (10, 54, 94, 166) and fluid ports in the valve housing (connected to or separated from one another in a fluid-conveying manner by a valve piston (22) displaceable along its longitudinal axis (24) in its various travel positions. A latching device (26, 28) latches the valve piston (22) in at least one of its travel positions. Individual latching parts (30, 38, 170) of the latching device, when it is actuated by an external force, take latching positions spatially different from one another with respect to the longitudinal axis (24) of the valve piston (22). The individual latching parts (30, 38, 170) of the latching device (26, 28) take positions differing from one another both in the axial direction and in the radial direction in the individual latching positions.
