Title:
AUTOMATIC TIRE AIR PRESSURE REGULATING DEVICE
Document Type and Number:
Japanese Patent JPS6154306
Kind Code:
A
Abstract:
PURPOSE:To save labor and time for checking and regulating a tire air pressure, by providing a valve control means for comparing a detection value according to an output from a pressure sensor with a pressure set value of a tire air pressure setting means, and generating an operational signal to a pressure valve. CONSTITUTION:The present device 1 comprises a power unit 10 and a control unit 20. An air tank 100 in the power unit 10 is supplied with compressed air from an air pump 105, and pressure in the tank 100 is detected by a pressure sensor 106 to permit the compressed air of a normally fixed pressure to be stored in the tank 100 by ON-OFF signal from an air pump control means 200. A valve control means 202 in the control part 20 acts to compare a detection value according to an output from a sensor 102 with a tire air pressure set value set by a tire air pressure setting means 201. If the detection value is lower than the set value, a pressure valve 103 is opened or closed to supply the compressed air from the air tank 100.
