This is a current source symbol.
It provides a constant current (whose value should be written next to the symbol), whatever the voltage across it. And basically, it's the opposite of a constant voltage source (ideal power supply).
Its meaning is not different from the usual symbol with a single circle.
Here are different symbols for current source: Source: https://commons.wikimedia.org/wiki/File:Ideal_current_source_symbols.svg
They all mean the same.
Your specific symbol is actually a mix of a and d. Half-US, half-european. A "melting pot" symbol, somehow.
