Patent ID: 8413683

Claim:
A pneumatic control valve device for a system for arbitrarily lifting and lowering a vehicle body of an air-suspended vehicle, comprising: control device having at least one mechanical control element having a lift position, a lower position, a drive position and a stop position; and a spring device for returning the at least one mechanical control element after it has been released, wherein the spring device returns the control element after it has been released into the drive position; a position securing device to mechanically lock the control element, wherein the position securing device, in a locked state, prevents the control element from returning under the spring force of the spring device into the drive position, permitting this in an unlocked state, and always permitting the control element to be manually adjusted, and wherein the position securing device can be changed from the locked state into the unlocked state by an electric signal; wherein, by the control element, a bellows air duct connected to at least one air spring bellows can be brought together with a closure element relative to mouths of air ducts, which are formed in the unit and are connected to one of a level control valve, a compressed air store and an air discharging arrangement, into positions permitting an air flow between the bellows air duct and a choice of one of the air ducts and at the same time closing the mouths of the other air ducts by the closure element, wherein the control element is actuated together with the bellows air duct and the closure element in a rotational manner with respect to a pivot axis, and latching openings in a latching body and the mouths of the air ducts are each arranged on a circumference of an imaginary circular line about the pivot axis, wherein the closure element is formed by an annular body which can be pivoted with the control element about the pivot axis and has a passage opening into which the bellows air duct leads, and wherein the mouths of the air ducts lie on an imaginary circular line about the pivot axis, and wherein the circular line coincides with an imaginary circular path along which the passage opening moves in the annular body for the bellows air duct during the rotational actuation of the control element, and wherein the annular body with the passage opening for the bellows air duct and the annular body with the latching openings each form annular segments which are arranged substantially in a plane perpendicular to the pivot axis.
