摘要： In a pair of sliding members (3, 5) sliding relative to each other on sliding surfaces (S), at least one of the sliding surfaces (S) includes a dynamic pressure generation mechanism (11), and the curvature of the dynamic pressure generation mechanism (11) is set to increase in proportion to the flow path length of the dynamic pressure generation mechanism (11). The sliding member can exhibit a pumping action even at low-speed rotation and can exhibit sealing function and lubrication function.

摘要： The disclosure concerns an applicator (e.g. print head) for applying a coating agent (e.g. paint) to a component (e.g. motor vehicle body component), having a nozzle chamber with a plurality of nozzles for dispensing the coating agent in the form of continuous jets or droplets, the coating agent flowing during operation through the nozzle chamber to the nozzles so that the nozzle chamber is filled with the coating agent during operation. The print head further comprises a plurality of slidable valve needles associated with the individual nozzles and selectively opening or closing the respective nozzle depending on the position of the valve needles. Furthermore, the print head according to the disclosure contains an actuator chamber for receiving actuators for displacing the valve needles. In addition, the applicator according to the disclosure has a sealing element which fluidically separates the actuator chamber from the nozzle chamber in order to avoid contamination of the actuator chamber with the coating agent in the nozzle chamber. The disclosure provides that the sealing element is designed such that the individual valve needles can be displaced independently of one another without a displacement of one of the valve needles impairing the opening and closing of the nozzles at the adjacent valve needle.

摘要： Two conflicting functions of sealing and lubrication of sliding faces are achieved for a long time. The sliding face of a rotating-side seal ring 3 is provided with dynamic pressure generation grooves 11 configured to communicate with the circumferential edge on the inner peripheral side of the sliding face and not to communicate with the circumferential edge on the outer peripheral side. A spring 7 is provided on the back side of a stationary-side seal ring 6 for pressing the stationary-side seal ring 6 against the sliding face of the rotating-side seal ring 3. A spring holder 8 is provided between the back side of the stationary-side seal ring 6 and the spring 7.

摘要： A seal assembly to seal a gas turbine hot gas path flow at an interface of a combustor liner and a downstream component, such as a stage one turbine nozzle, in a gas turbine. The seal assembly including a piston ring seal housing, defining a cavity, and a piston ring disposed within the cavity. The piston ring disposed circumferentially about the combustor liner. The piston ring is responsive to a regulated pressure to secure sealing engagement of the piston ring and outer surface of the combustor liner. The seal assembly includes at least one of one or more sectional through-slots, bumps or channel features to provide for a flow therethrough of a high-pressure (Phigh) bypass airflow exiting a compressor to the cavity. The high-pressure (Phigh) bypass airflow exerting a radial force on the piston ring.

摘要： There is disclosed a motor mount apparatus for coupling a pump body of a fluid pump assembly to a rotational power source (e.g. motor). The apparatus provides a plurality of seals and retaining seal members within a motor mount assembly to cooperate to seal the interior of the apparatus and prevent contaminants such as grit to enter into the interior of the motor mount assembly and subsequently into either the pump body or the power source. The retaining seal member comprises a seal and is fittedly engaged within the motor mount assembly surrounding a shaft coupler. Disposed between the shaft coupler and the shaft is a second seal for cooperating with the seal of the retaining seal member to block external contaminants from entering past the retaining seal member into the housing while containing lubricants on the interior facing side of the retaining seal member.

摘要： A fluid injector includes a valve assembly constructed and arranged to control flow of fluid from an inlet to an outlet of the injector. A metal housing surrounds at least a portion of the valve assembly. A plastic body is molded over at least a portion of the housing. A distal end of the body defines an integral stepped portion extending from the body. A carrier surrounds at least the distal end of the body. A seal member is in contact with at least the stepped portion and a surface of the carrier to prevent liquid from entering a space between the housing and the body.
