Flow Restrictor with Ball and Throttle

Abstract

A device for limiting the feed of fuel out of a high-pressure supply via a controllable injector into the combustion space of an internal combustion engine comprises a housing including a pressure supply-side housing inlet, an injector-side housing outlet, and at least one duct having a throttle, and a closing member longitudinally displaceable in a chamber between an initial position and an end position, spring-prestressed opposite to a flow direction, and configured to control a flow connection between the housing inlet and the housing outlet. The housing inlet is connected to the housing outlet via the at least one duct, and the at least one duct runs radially outside the chamber.
