Abstract

PURPOSE: To provide an approach rate detector where no mechanically movabl parts such as springs, etc are needed and external shocks for a stopper mechanism are protected by detecting the approach rate of a detected body through change of the air pressure in the stopper mechanism.
CONSTITUTION: A pressure P2 is produced by a pressure regulating valve 1 and a throttle value 2 and introduced to the nozzle 4 of a stopper 3, discharged to a detected body 6. The backpressure proportional to the discharge distance is effected on the pressure P2 and a pressure switch 5 driven by the pressure P2 is operated. By these performances is allowed to be guaranteed the operation of the instrument in accordance with the distance from the detected body 6. As the detected body 6 approaches the nozzle 4 of the stopper 3, the internal pressure P2 increases and approaches P1. Therefore, the approach rate of the detected body 6 can be measured by setting the pressure switch 5 at any pressure between P1 and P2. By taking this makeup, damages by external shocks can be avoided and, moreover, reliable performances be guaranteed.
