Just like if you decreased the voltage (ie, supply pressure) on two fixed resistors in series;
Ah ..but we don't have a series circuit when the pump is in relief. In a DC series circuit 100% of the current passes through a single pathway. This is not the case with a pump that is sending flow over two pathways at a common supply pressure.
One the pressure is the product of the current through a resistance. The other is the product of of the current passing at a given pressure.
Two distinctly different scenarios, don't you agree?
The upside of the filter and the internal relief effectively setup a "pool" of available flow at an attenuated pressure. The engine pressure is a result of that single series sub element to that "pool". As the shunt/relief takes less of that flow output ..the engine sees more ..it drops more pressure and elevates toward the supply. The filter, from an interior/exterior view is "less different" ..having a lower differential.
