TH31269B - Pressure indication device - Google Patents

Abstract

Pressure indication device (2) As an example for fixation to the tongue of a tire (1) exposed, the device holds a bendable diaphragm that cannot pass air (7) on the wall. one side of The airtight sealed chamber is permanently impenetrable (8) is pressurized to the The pressure is given to mechanical joints (10, 12), which move depending on If the pressure in the tire where the device is connected. Greater than or less than the pressure in the chamber (8) as an example will rotate. Two colored balls (14). Therefore, the colors shown will provide a visible signal that will indicate if the tire pressure exceeds or falls below the specified pressure. This can detect leaks or wasted air by quick look

Claims (5)

1.Pressure indication device consisting of enclosures (9) including inlet tubes (3) for pressurized air, permanently impermeable air-sealed chambers (8). This includes the pressurized gas, the flexible assembly (7) between the inlet pipe (3) and the chamber (8) and the signaling device (14), where the signal is dependent on the difference in signal strength. Pressure between the inlet pipe and the aforementioned chamber, and is characterized by The flexible assembly is a flexible, impermeable diaphragm (7) which, when the pressure at the inlet pipe (3) increases, is stretched into the chamber (8) with that pressure and The unique characteristics are The equipment includes a connection path (10, 12, 20) between the diaphragm (7) and the transmitting device (14), which is optimized to stimulate the transmission device (14) to generate a signal that Represents the inlet pipe pressure relative to the pressure in the sealed chamber. 2. Pressure indication device corresponding to claim 1, provided that the signaling device (14) is located in the chamber (8). Corresponds to claim 1 or 2, with the inlet pipe being Adjustment to open the rubber tongue (1,21) and form a face. Touch sealed (5) to the valve. 4. Pressure indication device corresponding to claim 3, whereby that chamber will be performed. Raise the pressure to approximate pressure which is lower than the appropriate tire pressure. For vehicles 5. Pressure indication device corresponding to one of the previous claims, provided that the inlet pipe contains an extension (6), which is adjusted to It is pressed against the center pin (21) of the tongue when it is connected to the rubber enclosure. 6. Pressure indication device corresponding to claim 5, where the inlet hose is assembled. Includes a seal (5) adjusted to seal the connection between the rubber enclosure (1) and the enclosure (9) of the device. 7. Pressure indication device corresponding to the claim. Any one of claims 1 to 6, where the signaling device (14) can provide at least two different signals. 8. Pressure indication device corresponding to the probe. The 7th right, whereby the transmission device The signal is a mechanical device 9. Pressure indication device corresponding to claim 8, whereby the transmission device The signal has been installed in a ball bearing (14) that can be rotated. Which the ball will have At least two colored areas 1 0. Pressure indication device corresponding to any of claims 1 to 9, provided that the indication device is: Visible indicators Places that can be observed from Outside the device with a minimum viewing angle of more than 110 degrees 1 1. Pressure indication device corresponding to any one of claim 1 to 10, where the connection path is mechanical connection 1. 2. Pressure indication devices in accordance with claim 11, whereby means of connection It is joined by a piston arrangement (10), a longitudinal assembly (12) and a crank trajectory (20), where the piston (10) will be fitted to the diaphragm (7), trajectory. The way of the crank (20) is attached to The transmission device (14) and the longitudinal assembly (12) extend between the piston (10) and the crank trajectory (20). 3. Pressure indication device corresponding to claim 12, provided that the piston (10) is pushed by a spring (13) towards the diaphragm (7) 1. 4.Pressure indication device corresponding to one of the first claim. Functionally where the diaphragm (7) is structured or assembled with a perforated disc (18) 1. 5. Pressure indication device compliant with claim 14, where the penetrating disc (18) is designed to penetrate If the pressure received on the side of the diaphragm (7) away from the chamber (8) is more than twice the pressure in that chamber.
