Tyre pressure measuring and indicating appts. - has remote control actuator with activating signal transmitter, with receiver in tyre valve cap

摘要

The tyre contains a valve cap with a housing closed at one side, while its open end is pressure-tightly screwed onto the tyre valve such that an actuating member opens the tyre valve. The appts. has a pressure sensor and a radio transmitter of a pressure signal. A hand held member, independent of the valve cap, contains a current source, a pressure signal receiving circuit, and a pressure display. The hand held member is formed as a remote control (50) and has an additional transmitter for an activating signal. The valve cap (10) contains a receiver for the activating signal for the pressure sensor and pressure signal transmission assembly after activating signal reception. ADVANTAGE - Simple and comfortable tyre pressure testing with increased precision.
