VALVE DEVICE HAVING A HOLD-DOWN ELEMENT
The invention relates to a valve device (1), comprising: - a valve housing (2), which has at least two connection openings (8, 9, 10) leading into respective chambers (25, 26) of the valve housing (2) and which is closed by a cover (3); - at least one sealing disk unit (11), which separates the two chambers (25, 26) from each other and has, as sealing disks (12, 13), a fixed disk (12) non-rotatably held in the valve housing (2) and at least one rotary disk (13) mounted for rotation about an axis of rotation (15), wherein the sealing disks (12, 13), which lie one on the other axially, each have at least one throughflow opening (14, 24) in order to open a throughflow cross-section between the chambers (25, 26) when the throughflow openings (14, 24) are in at least one position of overlap with each other; and - a spring element (29), which is held, under preload, between the rotary disk (13) and the cover (3); wherein the underside of the fixed disk (12) facing away from the rotary disk (13) lies axially on a housing-fixed protrusion (17). According to the invention, a hold-down element (32) is disposed in the valve housing (2) and is axially seated against the fixed disk (12) on one side and against the cover (3) on the other side.
