Motor vehicle wheel hub valve for inflating, deflating and monitoring tire pressure has membrane with outer rigid, central perforated and elastic sections

摘要

#CMT# #/CMT# The valve (5) has a membrane (22) held between a cover (21) and a housing (20) and forming control (23) and outlet (24) chambers, the latter connecting with the outside via a duct (26). It differs in that the membrane has a central perforated section (28) and alternating annular rigid section (29, 31) and elastically deformable (30, 32) sections. The membrane is associated with a diaphragm (34) that has two stable positions and a shut-off valve (35). The diaphragm is in the form of a star-shaped dome with inner and outer tips pressing against different parts of the membrane and a central ring pressed against the housing. #CMT#USE : #/CMT# Controlling the pressure inside a vehicle tire. #CMT#ADVANTAGE : #/CMT# The valve enables tire pressures to be monitored and adjusted while the vehicle is in motion. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-section of the valve. 5 : Valve 20 : Housing 21 : Cover 22 : Membrane 23 : Control chamber 24 : Outlet chamber 26 : Duct 28 : Central perforated section of membrane 29, 31 : Rigid sections 30, 32 : Deformable sections 34 : Diaphragm 35 : Shut-off valve.
