Abstract:
1. A fluid outlet chamber regulator for a cooling circuit of a cylinder head of an internal combustion engine, the chamber regulator comprising: a chamber component having an inlet and an outlet configured to regulate fluid, and the chamber component having at least one opening formed in an inner wall of the chamber component between the inlet and the outlet; a flow passage regulator which regulates a flow of the fluid passing through the chamber component in a longitudinal direction of the chamber regulator, the flow passage regulator having a valve movable in the longitudinal direction and configured to close a passage cross-section positioned between the inlet and the outlet of the chamber component, the valve being fixed to a longitudinally extending control shaft; and a closure configured to translate with the control shaft, the closure having two flat surface supports which extend parallel to two corresponding flat inner wall surfaces provided on the inner wall of the chamber component, wherein engagement between the two flat surface supports and the two corresponding flat inner wall surfaces provides two sliding contact surfaces as the closure translates within the chamber component, the closure being positioned on the shaft and having a shape configured to regulate the fluid flow passing through the opening in accordance with a regulation of the fluid flow through the passage cross-section, wherein during translation of the closure within the chamber component, the closure is locked against rotation.
