Abstract

PURPOSE: To minimize a fluctuation of release pressure by arranging a fuel cushion toward a bias spring additionally and connecting a fuel cushion with a flow passage through throttle connecting parts. CONSTITUTION: A fuel cushion 54 is arranged toward a bias spring 60 additionally. The fuel cushion 54 is connected with a flow passage 22 through throttle connecting parts 56, 58. The throttle connecting parts 56, 58 are prescribed so as not to generate an extreme fuel exchange between the fuel passage 22 and the surrounded fuel cushion 54 on the occasion of a process of open and close of a valve closing member 30. Thereby, a fluctuation of release pressure can be minimized.
