徴とするプレツシヤレギユレータ。 A pressure regulator that adjusts the fuel pressure applied to a fuel supply system that maintains a constant pressure difference between fuel pressure and intake pipe internal pressure by opening and closing a valve, and determines the fuel supply amount based on the valve opening time of an injector. 1. A pressure regulator characterized in that a shape memory alloy spring whose spring constant increases at high temperatures is disposed in a fuel passage so as to bias a valve in a closing direction.
