Pump Operation at Variable Speeds. In more severe conditions encountered in mobile vehicles 500010000 h of trouble-free operation is frequently achieved. Operating times of 24000 h or more in industrial applications are widespread.
Pump Operation at Variable Speeds.
The other end of the lever which is linked loosely to a rubber diaphragm forming the floor of a chamber in the pump goes down and pulls the diaphragm with it. A mechanical fuel pump is driven by the camshaft or by a special shaft driven by the crankshaftAs the shaft turns a cam passes under a pivoted lever and forces it up at one end.
