Flow structure for damping valve of pneumatic spring used in vehicle, has fluid channel whose length and shape are selected such that suction effect of fluid stream through fluid channel is produced at opening

摘要

#CMT# #/CMT# The flow structure has openings (531) for receiving the fluid stream from valve opening (641) of dampening valve, and for discharging fluid stream. A fluid channel is provided for conducting the fluid stream between openings. The length and shape of fluid channel are selected such that the suction effect of fluid stream through fluid channel is produced at opening. #CMT# : #/CMT# Independent claims are included for the following: (1) damping valve; and (2) pneumatic spring. #CMT#USE : #/CMT# Flow structure for damping valve of pneumatic spring (all claimed) used for attenuation of axle oscillation of vehicle. #CMT#ADVANTAGE : #/CMT# The oscillation in fluid channel is dampened and the absorbing power of damping valve is increased. The compact structure of damping valve is ensured. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the dampening valve. 108 : Damping valve 110 : External storage 120 : Internal volume 531 : Opening 641 : Valve opening.
