摘要： A seal assembly for pressurized fluid applications, including supercritical fluid chromatography applications, includes an annular body and a helical wound flat spring. A bore extends through the annular body. The annular body has an outer lip and an inner lip opposed to and spaced apart from each other. The inner lip, outer lip and an overhanging lip portion of the outer lip define a pocket in which the helical wound flat spring is disposed. A load line of the helical wound flat spring is directed substantially along a direction of separation between the inner and outer lips to bias apart the lips. Embodiments of the seal assembly have an improved distribution of contact pressure between the inside diameter of the seal assembly and the plunger with which the inside diameter seals, and between the outside diameter of the seal assembly and a gland surface with which the outside diameter seals.

摘要： A piston and cylinder assembly includes a housing defining a bore. A piston is sized to reciprocate in the bore. A first sealing member provides a sealing engagement between the piston and a wall of the bore. A first bushing, of a first material, is around a first portion of the piston toward a first end of the piston. A second bushing, of a second material, is around a second portion of the piston toward a second end of the piston. The first and second bushings guide the piston within the bore. The first material is different than the second material.

摘要： The present invention recites a method of fabricating a stator for a downhole motor, the method comprising the steps of providing a stator tube having an interior surface and applying a bonding agent to the interior surface of the stator tube. Additionally, a mandrel is positioned within the stator tube, the mandrel having an outer geometry that is complimentary to a desired inner geometry for the stator. Furthermore, a reinforcing material is introduced into the stator tube to fill space between the mandrel and the interior surface of the stator tube and subsequently solidified to bond the reinforcing material to the interior surface of the stator tube, The mandrel is then removed from the bonded stator tube and reinforcing material such that a stator is fabricated.
