Embodiment Construction

[0060] figure 1 A schematic and partially perspective view of a valve assembly 10 with a sealing unit 12 according to an embodiment of the invention is shown. The valve assembly 10 also has a valve member 14 and an end 16 of a fluid passage 18 . The valve element 14 is rotatable in the direction of the arrow 20 in order to control the coolant flow. Here, the coolant flows in the direction of the arrow 22 . The sealing unit 12 serves to seal the transition between the valve element 14 and the end 16 of the fluid channel 18 . The end 16 of the fluid channel 18 is formed in the region of the housing 24 .

[0061] The sealing unit 12 has a sealing ring 26 and a disk spring 28 . The sealing ring 26 seals the sealing unit 12 relative to the valve ring 14 . In contrast, the disk spring 28 seals the sealing unit 12 against the end 16 of the fluid channel 18 . In this case, the sealing ring 26 and the disk spring 28 are connected to each other in a sealing manner, so that no cool...

Abstract

The invention relates to a sealing unit (12) for sealing a transition between a valve element (14) and an end (16) of a fluid channel (18). The sealing unit (12) has a sealing ring (26) for sealing against the valve ring (14) and a disk spring (28) for sealing against the end (16) of the fluid channel (18). In this case, the sealing ring ( 26 ) and the disk spring ( 28 ) are connected to each other in a sealing manner.

Description

technical field [0001] The invention relates to a sealing unit for sealing a transition between a valve element and the end of a fluid channel. Furthermore, the invention relates to a valve assembly with such a sealing unit. Background technique [0002] Conventional internal combustion engines usually have one or more coolant circuits for cooling, wherein the coolant can be conducted, for example, through a first coolant path with a heat exchanger or through a second coolant path without a heat exchanger. coolant path. In order to regulate the amount of coolant to be conducted through the different coolant paths, a valve arrangement, for example a rotary slide valve, is usually provided. The valve assembly has an adjustable valve element, for example a rotary slide, which releases the passage between the fluid inlet channel and the first fluid outlet channel in a first valve position and releases the fluid in a second valve position. A passing portion between the inlet c...
