A coolant regulator is provided including a housing having a coolant chamber and a rotary vane arranged therein, a drive shaft leading out of the coolant chamber that rotates the rotary vane, and a shaft seal which seals the coolant chamber from the surroundings. The shaft seal seals against a housing inner lateral surface of a housing recess and sealingly encloses the drive shaft. An end portion of the shaft seal facing the rotary vane is a circular ring that, under elastic deformation of the bead thereof, seals against the housing inner lateral surface on the outer circumference and encompasses a spreading ring on the inner circumference that limits an axial shift of the shaft seal toward the rotary vane to a dimension d<s. s is the axial distance between the bead center of the undisplaced shaft seal and the opening of the housing recess facing the rotary vane.

A split oil seal composed of double springs and double rings comprises an elastic outer ring intended to be statically mounted in a cavity outside a bearing box or gear box, and an elastic inner ring intended to be sleeved on a shaft of the device and held by the outer ring. The outer ring has an outer ring cut and the inner ring has an inner ring cut. The split oil seal further comprises a radial forcing element and a circumferential forcing element, wherein the radial forcing element exerts tension in both directions directed to outer circumferences and inner centers of both the outer ring and the inner ring in radial directions thereof, and the circumferential forcing element exerts a circumferential closing force to the inner ring. By using the split oil seal composed of double springs and double rings of the present invention, the advantages of convenient mounting and removal as well as strong anti-disengaging ability are achieved.

A multi-layered lip seal comprising a dynamic layer optionally having a filler incorporated therein and a static layer optionally having a filler incorporated therein is described. The lip seal has an annular ring shape, wherein an inner diameter of the ring shape is curved in an axial direction so as to give the lip seal a J-shape when viewed from a cross-sectional perspective. Fillers that can be included in static layer include stiffening filler, reinforcement fillers, conductive fillers and/or abrasion resistance fillers. Fillers that can be included in the dynamic layer include wear resistance fillers. The use of specific fillers in specific layers of the multi-layered lip seal allows for certain segments of the lip seal to be imparted with the benefits of the filler without negatively impacting other segments of the lip seal.

A seal assembly includes an outer annular case disposed within and coupled with a rotatable outer member to be angularly displace about a central axis. An annular flexible seal is disposed within and coupled with the case to angularly displace about the central axis when the outer member rotates about the axis. The flexible seal has elastomeric sealing lip(s) engageable with an outer circumferential surface of the shaft or of a sleeve disposed about the shaft. An annular inner rigid seal is disposed within the outer case and has an inner end coupled with the shaft or the sleeve, the flexible seal being radially displaceable with respect to the inner rigid seal. An outer annular rigid seal is disposed about the inner seal and has an inner end sealing against the inner rigid seal. A biasing member biases the outer rigid seal against the inner rigid seal.

A compliant seal in a valve mechanism in a supply station for coupling to a build material container and a method for sealing a build material container are provided. The compliant seal includes a seal ring including a contact surface configured to allow the build material container to rotate while maintaining a sealed channel between the valve mechanism and a build material container. A feature in a back surface of the seal ring opposite the contact surface mates to a corresponding feature on the valve mechanism to prevent the compliant seal from rotating with the build material container A guide ring mounted over an outer portion of the seal ring is configured to direct a build material container into contact with the contact surface as the build material container is inserted into the supply station.

A continuous length of formed metal retaining material can be cut to the partial or full circumference or perimeter of at least one assembly component and disposed in a groove of at least one assembly component to form a retaining ring engaging at least one other assembly component. The retaining ring prohibits lateral and rotational movement.
