摘要： A system for transmitting information of reduced pneumatic pressure of tires comprising an electromagnetic wave radiation mechanism of an electric field excitation system and at least one receiver antenna of an electromagnetic field sensing type for sensing a polarized wave of an electromagnetic field radiated from the radiation mechanism. The radiation mechanism includes an electromagnetic wave radiation member consisting of a substantially concentric metal body opposedly and substantially provided on each axle of a plurality of tire wheels for actuating as an electric dipole together with the wheels and an oscillator electrically coupled to the radiation member and energized by a switch actuated in response to reduced pneumatic pressure of tire. The receiver antenna is provided in the space between the ground surface and the lower surface of the bottom plate of the car body in order to screen external noise waves.

摘要： The tyre pressure monitor has a resonant circuit(5) on the wheel, operated when the tyre pressure falls below the set value. This provides a strong signal which is detected by an oscillator circuit(10) on the chassis, which in turn operates the warning circuit (12) on the dashboard. The system is highly sensitive and is unaffected by outside interference, such as from the ignition circuit. The resonant circuit is tuned to the oscillator.

摘要： There is described a pressure-responsive switch device particularly suitable for the detection of a pressure drop in a pneumatic tire on a vehicle wheel, wherein a contact carrying movable rod member is securely urged into a contact closing position by means of a conical compression spring to actuate a warning device whenever the internal pressure of the tire drops below a predetermined level. A permanent magnet may be mounted at the contact point of the switch to impart a quick motion thereto.

摘要： A pressure-sensitive switch unit forming part of a resonator assembly for use in a tire pressure drop detecting apparatus of the electromagnetic induction type, wherein an atmospheric chamber, formed in a casing structure and hermetically isolated by a diaphragm from a pressure-acting chamber communicating with the tire chamber in a tire-and-wheel assembly, communicates with the atmosphere through contact surfaces of two or three of the component parts of the casing structure and further through a body of a gas-permeable synthetic rubber in part exposed to the atmosphere so that an atmospheric pressure is at all times introduced into the atmosphere atmospheric chamber and an ingress of water and dust into the atmospheric chamber is precluded by the body of the gas-permeable synthetic rubber.
