The arm has a flange that fastens with 4 screws to the bottom of the carburetor, and sealed with a rubber diaphragm integral with the main jet.

The rubber diaphragms that sealed off the air-brake chambers had been in place for just over 100, 000 miles, which is when they are supposed to be replaced.
13.
For vacuum-or pneumatically operated zone valves, the thermostat usually switches the pressure or vacuum on or off, causing a spring-loaded rubber diaphragm to move and actuate the valve.
14.
For vacuum-operated or pneumatically operated zone dampers, the thermostat usually switches the pressure or vacuum on or off, causing a spring-loaded rubber diaphragm to move and actuate the damper.
15.
For this reason, the tanks were equipped with a rubber diaphragm that would burst when the helium pressure reached a certain level and allow the gas to vent harmlessly into space.
16.
Their disadvantage is that they need a specific length of tubing and high quality rubber diaphragms, which are costly and are relatively inefficient due to the extra work needed to deform the diaphragm.
17.
When two or more units are coupled together in a single train, the entire front door folds away to give a wide passage, and the rubber diaphragms at the ends form a flush aerodynamic seal.
18.
:The Hydraulic analogy is sometimes used to help students grasp electronic processes ( by letting fluid pumps / pipes / pressure / fluid flow / fluid volume / pipe constriction / rubber diaphragm stand in for electric generators / wires / voltage / current / charge / resistor / capacitor respectively ) in an intuitive way but is clumsy when it represents an inductor.
