OPW 11B Pressure-Sensing Automatic Nozzle 

Whoever came up with this idea is a genius.

Truly elegant, thanks hank!

I didn’t realise there’s so much engineering that’s gone into a bowser

How did I end up here ?

My petrol station pump keeps shutting off even when my car has no fuel

When it shows the vacuum pulling on th diaphragm, isn't the wrong side of the diaphragm colored? I'm a little bit confused, since it would have to push on the side it is shown.

... Music from a 90's movie-endscene

Will this type of automatic nozzle work with a 55-gallon drum with hand rotary pump? Or does it require constant flow/pressure and the hand pump may not be 100% constant.

Um... At 1:03 this video shows "green" vacuum _below_ the diaphragm, yet claims that the vacuum "creates a quick _upward_ flex of the diaphragm". How can vacuum _below_ the diaphragm create an _upward_ flex??? You'd need vacuum _above_ the diaphragm for that to happen. Whoever made this video completely screwed up the green highlighting at 1:03. The "green" is supposed to be placed _above_ the diaphragm. The current display of the venturi shut-off action makes no sense.

The last thing happened to my dumbass today. Check the triggers on your pumps people!

now i know how it shuts off automatically

why is the music so bangin

Very cool

Yes

Why's this video got so many views and how did I get here?

👏👏👊👊

Makes no fucking sense

Why did Dover have to sell off their elevator division ☹️. Don't the people deserve low cost reliable elevators?
