摘要： A rotary shaft sealing assembly having a rotatable shaft, a seal housing having a groove bore located radially outward of and facing the rotatable shaft, and a sealing element in sealing contact with the shaft and groove bore. The sealing element having seal body first and second ends and tangs extending axially from the seal body first end. A shelf member has an outer groove wall and a shelf defining an inner groove wall. The inner and outer groove walls providing axial support to the sealing element in certain conditions of assembly and operation. The seal housing or the shelf member providing restraints, with a portion of the restraints in circumferential alignment with the tangs and blocking rotation of the sealing element. The shelf, located radially between the shaft and the restraints, blocks and prevents loss of the restraints.

摘要： A hydrodynamically lubricating rotary seal for differential pressure acting in either axial direction that establishes compressed sealing engagement with a relatively rotatable surface and wedges a film of lubricating fluid into the interface between the rotary seal and the relatively rotatable surface in response to relative rotation that may occur in the clockwise or counter-clockwise direction. A multi-function edge and angled flank of the hydrodynamic wave form are truncated by the lubricant end of the seal, improving the dynamic performance of the seal in circumstances where the pressure acting on the environment end of the seal is greater than the pressure acting on the lubricant end of the seal. This improvement is believed to be the result of reduced contact pressure, and reduced radial deformation of the wave form, compared to prior art seals.

摘要： A sealing assembly includes a first machine component having a seal groove defined by radially oriented jacket support and energizer positioning walls and an energizer compressing wall that faces axially toward a second machine component. A seal located within the seal groove has an energizer element and a telescoping jacket. The jacket has a first leg portion having a jacket sealing surface facing toward the second machine component and an energizer contacting wall facing toward the energizer element. The energizer element is compressed between the energizer contacting and energizer compressing walls and loads the jacket sealing surface against the second machine component. A jacket second leg portion extends generally axially and has an energizer supporting wall facing toward the energizer element and a supported wall facing radially and adjoining the jacket support wall. The second leg portion is interposed between the energizer element and the jacket support wall.

摘要： A seal backup ring assembly is provided that eliminates fluid differential pressure acting radially on the backup ring, preventing collapse of the backup ring against a shaft. The backup ring is assembled so that the initial clearance (extrusion gap) between the backup ring and relatively rotating member is not affected by the differential pressure acting across the assembly. This allows for an initially small extrusion gap to be present throughout the differential pressure range.

摘要： The present invention is a generally circular rotary seal that establishes sealing between relatively rotatable machine components for lubricant retention and environmental exclusion, and incorporates seal geometry that interacts with the lubricant during relative rotation to distribute a lubricant film within the dynamic sealing interface. The features of a variable inlet size, a variable dynamic lip flank slope, and a reduction in the magnitude and circumferentially oriented portion of the lubricant side interfacial contact pressure zone at the narrowest part of the lip, individually or in combination thereof, serve to maximize interfacial lubrication in severe operating conditions, and also serve to minimize lubricant shear area, seal torque, seal volume, and wear, while ensuring retrofitability into the seal grooves of existing equipment.

摘要： A rotary seal is provided that operates hydrodynamically in response to relative rotation even when subjected to exposure to a high fluid pressure from either side, and provides low breakout and running torque. A dynamic sealing lip having a wavy geometry provides hydrodynamic lubrication in response to relative rotation when little or no differential pressure is acting across the seal. When differential pressure exists, controlled fluid pressure-induced distortion results in a distorted dynamic sealing lip configuration that is suitable for hydrodynamic lubrication, regardless of which direction the differential pressure acts from.

摘要： A passive thermal control valve comprising a thermal actuator coupled to a valve body having first and second ports. The thermal actuator including an actuator body having an inner bore. An adjustment stop engages the actuator body. A cylinder is received within the actuator body inner bore and the cylinder has a cylinder bore open at one end. An actuator spring within the actuator body biases the cylinder towards the adjustment stop. An actuator rod is at least partially received within the cylinder and has first and second ends. At least a portion of the actuator rod is allowed to extend through the open cylinder bore. A sealing element forms a seal between the actuator rod and the cylinder and defines a sealed chamber within the cylinder. A thermal fluid is contained within the cylinder. A lever mechanism is connected to the valve body and includes a lever having a first end connected to the valve body. A valve spool is connected to a lever second end. The valve spool is arranged and designed to close the first port and allow a system fluid to flow through the second port, close the second port and allow the system fluid to flow through the first port, or allow the system fluid to flow through both the first and second ports.
