Flow controller
First Claim
1. A preadjustable flow controller for a heating system comprising:
- a housing that has an inlet connection for a heating medium, an outlet connection for the heating medium, and a preadjustment connection;
a rate regulating module, which depending on a preadjustment and a pressure difference changes a flow for the heating medium; and
a handle that acts together with the rate regulating module to preadjust the flow,wherein, to change the preadjustment of the flow via the handle, an effective cross section of a first flow-through opening for the heating medium is adjusted,wherein, to regulate the preadjusted flow of the heating medium, a sleeve of the rate regulating module and a cup of the rate regulating module, which are provided spring-loaded to one another via a bias spring, are disposed axially movable to one another and depending on an axial position, which varies with the pressure difference, a cross section of a second flow-through opening for the heating medium is changed,wherein the inflow to the rate regulating module occurs via the first flow-through opening, which is provided through the sleeve and is provided upstream of the second flow-through opening based on a flow direction of the heating medium, andthe second flow-through opening is provided on an axial end the cup, thereby the inflow from the first flow-through opening passes on the outer cylindrical surface of the cup through the second flow-through opening.

Abstract
A flow controller for a heating system with a housing, which has an inlet connection for a heating medium, an outlet connection for the heating medium, and a preadjustment connection, with a rate regulating module, and with a handle, which acts together with a movably disposed structural element of the rate regulating module to preadjust the flow. To change the preadjustment of the flow via the handle, an effective cross section of a first flow-through opening for the heating medium can be adjusted and to regulate the preadjusted flow of the heating medium, a sleeve of the rate regulating module and a cup of the rate regulating module are disposed axially movable to one another. The inflow to the rate regulating module occurs on an outer side via the first flow-through opening which is provided on the sleeve and upstream of the second flow-through opening.
