Flow regulator for dosing pump - has metering piston forming housing for regulating valve

摘要

The regulator has a metering feed with a linearly displaceable piston (6) sliding in a housing (5) with a chamber (15) connected to the delivery side of a pump (16), and a second chamber (17) connected to an output. A regulating valve gate also moves in a housing (19) with one chamber selectively connected to one of the chambers of the regulator. The piston for the regulator forms the housing for the regulating valve gate, which is formed as a slide (20). One of the metering chambers can also form the chamber for the regulating valve.
