Abstract

A device (1) for regulating a coolant flow in a cooling system of an internal combustion engine (2) with a valve arrangement (3) that includes a rotary disk valve (4) for switching at least one cooling circuit (5, 6) and / or a bypass circuit (7), as well as a coolant pump (8) that is constructed as an impeller pump and is connected on the suction side to the valve arrangement (3). The coolant pump (8) has an axial adjustable guide plate (11) on an inside between two end stops (9, 10) for closing and releasing a pump outlet (12). The guide plate (11) for the axial adjustment is indirectly coupleable by a lead screw thread (13) to a drive shaft (14) of the rotary disk valve (4). A cooling system for an internal combustion engine (2) with such a device (1) is also provided.

Description

technical field

[0001] The invention relates to a device for regulating the flow of a cooling medium in a cooling system of an internal combustion engine, having the features of the preamble of claim 1 . Furthermore, the invention also relates to a cooling system with such a device. Background technique

[0002] Today, internal combustion engines are essentially cooled with water. For this purpose, cooling water is pumped into a closed circuit by means of a cooling medium pump or a cooling water pump through cooling ducts in the cylinder area in order to cool the internal combustion engine and is then conveyed to the air-water cooler, where it is heated The warm water is cooled down again by the driving wind. The pumps required for circulating the water are preferably driven by the internal combustion engine. For this purpose, the pump is usually connected via a belt to the pulley of the crankshaft of the internal combustion engine.

[0003] In this case, the direct coup...
