Task

Allowing a defined quantity of fuel (determined by the restrictor) to flow back to the fuel tank

Maintaining fuel pressure (A) in interior of pump

Bleeding distributor injection pump at start

Function

The overflow valve with restrictor (15/1) alows a variable quantity of fuel (C) to flow back to the fuel tank over the spring-tensioned slide (c) and the drilling (a). The drilling (a) 0.7 mm represents a resistance, as a result of which the fuel pressure (A) is retained in the interior of the pump. The bypass (b) 0.2 mm in the slide (c) is used for achieving better breathing during start.
