Abstract: A seal arrangement for a fluid valve includes: a first seal for sealing abutment against a pivotably adjustable valve body of the fluid valve; a second seal for sealing abutment against a valve housing of the fluid valve; and a separate, elastically deformable intermediate piece arranged between a first wall of the first seal and a second wall of the second seal. The intermediate piece has at least one axial section whose cross section has, in relation to the seal opening, a first, radially outer lateral surface and an opposite, second, radially inner lateral surface, and the radially outer lateral surface is at least sectionally concave, and the radially inner lateral surface is at least sectionally convex.

Abstract: A seal for use in a fluid valve, or multi-path fluid valve, has a cylindrical, resilient base member, a plurality of first sealing portions arranged at an outer side of the base member for sealing abutment against a valve housing of the fluid valve, and a plurality of second sealing portions, arranged at an inner side of the base member, for sealing abutment against an adjustable valve body of the fluid valve. A respective first sealing portion and respective second sealing portion are arranged circumferentially around a respective sealing opening of the base member. There is arranged at the inner side of the base member a first layer having a sliding friction coefficient which is less with respect to the valve body and/or static friction coefficient which is less than the base member, and which is at least partially in contact with the valve body during use of the seal.

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.

Abstract: A fluid drain off system for a fuel filter, the system comprising a float, movable together with a trigger device for a switch, such as a magnet, in response to the level of fluid contaminant, a switch arranged to be selectively triggered by the trigger device upon the fluid contaminant reaching a predetermined level, and a fluid passage configured to be selectively opened in response to the triggering of the switch to allow fluid contaminants to be drained from the filter.
