摘要： A seal housing is disposed to support an axially facing seal segment, and comprises a substrate and a coating. The substrate has an inner annular surface, an axially facing substrate surface, and a corner feature at an intersection of the inner annular surface and the axially facing substrate surface. The corner feature includes an annular notch in the inner annular surface, and a chamfer extending from the annular notch to the axially facing substrate surface. The coating is formed on the axially facing substrate surface and into the corner feature of the substrate, and has a coating surface, parallel to the axially facing substrate surface, that terminates at the inner annular surface and abuts the seal segment.

摘要： A filler assembly is mounted in an axial hole of a cap of a valve. The filler assembly includes at least one first filler and at least one second filler stacked in a longitudinal direction. A valve rod received in the axial hole extends through the at least one first filler and the at least one second filler. At least one of two mutually abutting faces respectively of the at least one first filler and the at least one second filler is at a non-parallel angle to a radial direction perpendicular to the longitudinal direction. If one of the at least one first filler and the at least one second filler is subjected to a pressing force in the longitudinal direction, at least one of the at least one first filler and the at least one second filler is moved in the radial direction to press against the valve rod.

摘要： The seal arrangement (1) for piston compressors comprises a deformable ring support (2) and a first and a second endless sealing ring (3a, 3b), wherein the ring support (2) has a longitudinal axis (L) which extends perpendicularly with respect to its circumferential direction, and wherein the ring support (2) has a gap (2i) with play in its circumferential direction, and wherein each sealing ring (3a, 3b) has a longitudinal axis (3c, 3d) which extends perpendicularly with respect to its circumferential direction, and wherein the sealing rings (3a, 3b) are arranged in such a way that the ring support (2) encloses them from the outside, and wherein the two sealing rings (3a, 3b) are arranged next to one another in the direction of extent of the longitudinal axis (L), and wherein the ring support (2) and the sealing rings (3a, 3b) are designed to be adapted to one another in such a way that the first sealing ring (3a) bears on one side against a first side wall (2d) of the ring support (2) and forms a first gap (S1) to the ring support (2) on the opposite side with regard to the longitudinal axis (3c) of the first sealing ring (3a), and wherein the second sealing ring (3b) bears in a diametrically opposed manner on one side against a second side wall (21) of the ring support (2) and forms a second gap (S2) to the ring support (2) on the opposite side with regard to the longitudinal axis (3d) of the second sealing ring (3b), wherein the first and second side walls (2d, 21) are arranged so as to lie opposite one another with regard to the longitudinal axis (L), with the result that the ring support (2) can in each case bring about a prestressing force (5a, 5b) on the first and second sealing rings (3a, 3b) respectively via the first and second side walls (2d, 21) respectively, wherein the prestressing forces (5a, 5b) extend in an opposed manner.

摘要： A bearing seal assembly includes a pair segmented circumferential or a carbon ring seals to contain oil in the bearing compartments of a gas turbine engine or other mechanical device. The pair of seals, an oil-side seal and an air-side seal, are axially-spaced between the oil and the air in the housing. Air at an elevated pressure is introduced between the seals. This elevated air pressure urges the seals axially apart from one another and radially inward to improve the seal. A backup seal is provided adjacent either the oil-side seal or the air-side seal. In the event of failure of either the oil-side seal or the air-side seal which results in the loss of air pressure, the backup seal will provide at least a minimum level of seal between the oil compartment and the air in the housing.

摘要： A piston sealing arrangement for pressure-fluid-operated systems is disposed in an annular recess of a piston (5) or an associated housing (4) and is composed of a sealing ring element (1A, 1B) as well as an elastic element (2, 3) acting on one side in opposition to the direction of the pressure force (A). Herein the elastic element is dimensioned such that the sealing ring element (1) moves against its elastic element (2, 3) at a pressure smaller than the force against which the piston (6) is moving and by which it is kept on its stop, a pressure-fluid film being formed as a result which safeguards a uniform initial movement of the piston to a largest possible degree.

摘要： A stuffing-box for sealing between an elongate member and a housing sleeve, in which packing material accommodated within a shouldered recess formed in the housing sleeve is pressed into contact with the elongate member by means of a loading medium introduced into the stuffing-box through ducting formed in the stuffing-box. Advantageously, the packing material is carried in a packing carrier which is mounted in the shouldered recess, and the packing material is in the form of a pre-formed packing sleeve, so as to permit the use of standardised packing sleeves and carriers for stuffing-boxes with shouldered recesses of different sizes.
