Embodiment Construction

[0037] figure 1 A perspective view of valve assembly 10 is shown. Valve assembly 10 has a seal assembly 12 , a fluid supply passage 14 and a valve element 16 . Here, the sealing assembly 12 serves to seal the passage between the fluid supply channel 14 and the valve element 16 . The fluid supply channel 14 is shown by means of dashed lines. The valve element 16 is adjustable and can have a rotary slide, wherein the fluid flow can be stopped or directed in different directions in different positions of the valve element 16 . The fluid flow can be, for example, the coolant flow of an internal combustion engine.

[0038] figure 2 A schematic cross-sectional view of the right side portion of valve assembly 10 with seal assembly 12, fluid supply passage 14 and valve element 16 is shown. The sealing arrangement 12 has a guide sleeve 18 , a sealing sleeve 20 and a pretensioning element 22 . The guide sleeve 18 , the sealing sleeve 20 and the pretensioning element 22 can be arr...

Abstract

The invention relates to a sealing assembly (12), in particular for sealing a passage between a fluid supply channel (14) and a valve element (16), the sealing assembly having a guide sleeve for sealing relative to the fluid supply channel (14) A sleeve (18), a sealing sleeve (20) movable relative to the guide sleeve (18) in the axial direction (26) for sealing against the valve element (16), and a sealing sleeve (20) for sealing in the axial direction (26) The pretensioning element (22) presses the guide sleeve (18) and the sealing sleeve (20) away from each other. Furthermore, the guide sleeve (18) has a guide tube (28) made of a first material and a seal (30) made of a second material. Here, the seal ( 30 ) is set up to seal the guide tube ( 28 ) against the sealing sleeve ( 20 ) and / or against the fluid supply channel ( 14 ). Furthermore, a seal (30) is fixedly connected to the guide tube (28).

Description

technical field [0001] The invention relates to a sealing assembly, in particular for sealing a passage between a fluid supply channel and a valve element, said sealing assembly having: a guide sleeve for sealing relative to said fluid supply channel; an element-tight sealing sleeve movable in an axial direction relative to the guide sleeve; and a pretensioning element for pressing the guide sleeve and the sealing sleeve away from each other in the axial direction . In addition, the invention relates to a valve assembly with such a sealing assembly. Background technique [0002] Conventional internal combustion engines usually have one or more coolant circuits for cooling, wherein the coolant can be conducted, for example, via a first coolant path with a heat exchanger or via a second coolant path without a heat exchanger. lead. In order to regulate the amount of coolant to be conducted through the different coolant paths, valve arrangements such as rotary slide valves ar...
