ABSTRACT:
An air leakage warning device for a pneumatic tire is described which comprises a housing member including in longitudinal direction a cylindrical intermediate section, an enlarged cylindrical lower section connected to the cylindrical intermediate section through a shoulder portion, and a four-sided upper section having a circular at the outmost end; a cylinder or tubular member containing a perforated piston means and a coil spring responsive to a predetermined pressure within the tire, the upper end of the cylinder member being inter-connected with the lower section of the housing member while the lower end thereof is secured to a base member which is adapted to be secured to the air filling valve stem of the pneumatic tire; a rubber ball being freely movable in the space defined by the housing member and the upper end of the cylinder member; and a rubber sack forming a receiver for escaping tire air and adapted to be ruptured by its contained air pressure so as to give an audible signal, the rubber sack having an inwardly directed annular rim integrally provided on the circumference of the sack opening to be firmly anchored between the cylinder member and the base member. When the air pressure of the tire is reduced to the predetermined value, the piston means will open the air filling valve to permit the escape of the air from the tire into the device and thereby to inflate and rupture the rubber sack. Thereafter, the rubber ball is blown into a position inside the four-sided upper section of the housing member to block the circucular opening of the housing member and thus prevent further escape of air.
