Abstract
A valve assembly is provided and includes a pitot tube having an angled tip to extract from a duct formed by a housing a sample of a fluid to be communicated to an actuator configured to operate the duct, the pitot tube being disposed within the housing whereby the pitot tube is fixed longitudinally between the actuator and the housing and laterally within the housing and an anti-rotation mechanism coupled with the pitot tube to rotationally secure the pitot tube such that the angled tip is fixed to face rearwardly.
Claims4
A method of forming a valve assembly having a housing, the method comprising:
- machining a first through-hole into the housing;
- machining a slot partially along the first through-hole;
- coupling an anti-rotation mechanism with a pitot tube to form a pitot tube assembly;
- and
- installing the pitot tube assembly within the first through-hole such that the anti-rotation mechanism sits within the slot,
- wherein the machining of the slot comprises machining the slot to extend from an upper surface of the housing and along a partial length of the first through-hole.
