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.

Abstract: According to one embodiment of the invention, a control valve for regulating temperature comprises a conduit, a fluid limiter, a restoring actuator, an opening actuator, and a restoring actuator chamber. The conduit has an inlet, an outlet, and an opening between the inlet and the outlet. The inlet is operable to receive fluid into the conduit and the outlet is operable to dispense of fluid out of the conduit. The fluid limiter is operable to at least partially cover the opening and thereby resist flow of fluid through the opening. The restoring actuator is operable to provide a force that moves the fluid limiter toward the opening to resist flow of fluid through the opening. The opening actuator is operable to provide a second force that moves the fluid limiter away from the opening to allow the flow of fluid through the opening. The opening actuator is activated based on a temperature of fluid in the conduit.
