  • Patent number: 11255444
    Abstract: A seal arrangement for use in a fluid control valve includes: a first seal configured to sealingly abut against an actuatable valve body of the fluid control valve; a second seal configured to sealingly abut against a valve housing of the fluid control valve; and an elastically deformable intermediate spacer, arranged between the first seal and the second seal and configured to elastically space the first and second seals apart. At least in an installed state of the seal arrangement in the fluid control valve, the first seal and the second seal are joined to one another in positively locking fashion in an axial direction of the seal arrangement.

  • Publication number: 20170363220
    Abstract: The present invention relates to a multiway valve for controlling at least one flow of at least one fluid, in particular within a motor vehicle, including at least one housing and one valve member disposed at least in areas within at least one valve space which is configured at least in areas within the housing, and by way of changing a rotary position of the valve member within the valve space about a first rotary axis, at least the amount of an inflow of the fluid from at least one first fluid connector into the valve space and/or at least the amount of outflow of the fluid out of the valve space is adjustable by at least one second fluid connector, and the multiway valve includes at least one insert which is disposed at least in areas between the valve member and the housing and is connected in a rotationally fixed manner to the housing.
