| 摘要 |
The invention relates to a pressure regulator for a fuel injection system of an internal combustion engine, in which a pressure difference prevailing between a pressure inlet and a pressure outlet can be kept essentially constant by opening and closing at least one valve, which valve includes a valve closing member forced into the closing position against a valve seat by the action of a valve closing spring. The valve spring is formed by means of at least one pivotably supported valve leaf spring, and an arm, toward the valve seat in terms of the pivotable bearing means, of the valve leaf spring is braced on the valve closing member, and an arm of the valve leaf spring located on the side opposite the valve seat is braced on a support body, in such a way that a torque equilibrium prevails at the valve leaf spring.
