Abstract
An air is fed from an air supply source to a detecting nozzle via a first fixed throttle section. The air is jetted from the detecting nozzle to the workpiece W to obtain a nozzle back pressure for detecting a position of a workpiece W. A first diffuser section is disposed downstream of the first fixed throttle section.
Claims6
A position-detecting apparatus for detecting a position of an object by supplying a fluid from a fluid supply source to a nozzle via a fixed throttle section and by jetting said supplied fluid from an end of said nozzle to said object for obtaining a nozzle back pressure,
- wherein a diffuser section is disposed downstream of said fixed throttle section.
A position-detecting apparatus for detecting a position of an object by supplying a fluid from a fluid supply source to a nozzle via a fixed throttle section and by jetting said supplied fluid from an end of said nozzle to said object for obtaining a nozzle back pressure,
- wherein said position-detecting apparatus has a cylindrical main body section, and a fixed throttle section, a diffuser section, and a nozzle are coaxially disposed in said main body section.
