Abstract:
A seal for a cable and connector interconnection includes a unitary elastic body with a bore therethrough. The bore is provided with a cable outer diameter seal portion at a cable end, the cable outer diameter seal portion adjacent a connector cavity portion, the connector cavity portion adjacent a coupling nut cavity portion, and the coupling nut cavity portion adjacent a connector neck seal portion with a bulkhead seal at a connector end. The coupling nut cavity portion is longitudinally aligned with a coupling nut of the connector and is provided with a greater inner diameter than the cable outer diameter seal portion and the connector neck seal portion. The bulk head seal is provided with an outer diameter greater than an outer diameter of the connector neck seal portion.
Abstract:
The present disclosure relates to an aircraft brush seal comprising a first brush seal member and a second brush seal member comprising a channel that receives a plurality of interwoven brush fibers. The interwoven brush fibers may be coupled to the first brush seal member and/or may extend into the second brush seal member. The interwoven brush fibers may not couple to the second brush seal member and/or may form an air seal. The air seal may be formed between a first air compartment and a second air compartment.
Abstract:
This invention relates to a compressible seal (34) for sealing a shaft. In order to obtain a tight seal suitable for use in high temperatures the seal comprises a shaft contact surface and an opposite contact surface, a seal structure comprising fire retardant particles (10) between the shaft contact surface and the opposite contact surface, and a diffusion barrier (11) of a metallic fluid tight material which extends between the shaft contact surface and the opposite contact surface for preventing leakage through the seal.
Abstract:
A metal fastener is provided having a first threaded screw portion for engaging a complementary threaded portion of a bore of a metal member at a first temperature, and a sealing portion disposed proximal a distal end of the first screw portion, the sealing portion having a greater coefficient of thermal expansion than the metal member, wherein the sealing portion is configured to thermally expand and provide a seal between the sealing portion and an inner circumference of the bore at a second temperature higher than the first temperature, such that the first screw portion of the fastener is immobile relative to the bore at the second temperature.
Abstract:
A seal configured for use in a chiller refrigeration system is provided including a first flange and a second flange. The first flange and the second flange are coaxially aligned and in direct contact. The second flange includes at least one groove within which a first sealing mechanism and a second sealing mechanism are positioned. The first sealing mechanism and the second sealing mechanism are separated by a distance such that a chamber configured to receive a pressurized gas is formed between the first and second sealing mechanisms.
Abstract:
A system for use in a pressurized atmosphere or medium includes a shaft housing (56), a shaft (54) rotatably accommodated within the shaft housing (56), and a pressure compensator (2) for transferring a first compensation pressure (P1) via a pressure fluid (6) to a first space. The shaft (54) and shaft housing (56) jointly define a shaft compartment (58), wherein at least three bearing seals (531, 532, 533) are provided between the shaft (54) and the shaft housing (56) positioned at different axial positions along the shaft (54).The bearing seals (531, 532, 533) shield the shaft compartment (56) with respect to an environment having an ambient pressure (P0), creating a first space (41) between a first and second bearing seals (531, 532) and a second space (42) between the second and third bearing seals (532, 533). The pressure compensator (2) comprises a reservoir (5) with a variable internal volume which is arranged to contain the pressure fluid (6) and is influenced by ambient pressure (P0). The pressure compensator (2) comprises a first supply pipe (32), being in fluid communication with the reservoir (5) and the first supply pipe (32) being connectable to the first space. The pressure compensator comprises a second supply pipe (36) being in fluid communication with the reservoir (5) and being connectable to a second space for transferring a second compensation pressure (P2) to a second space. The second supply pipe (36) comprises a pressure resistance or pressure regulating device (38) positioned in the second supply pipe (36). The first supply pipe (32) is in fluid communication with the first space (41) and the second supply pipe (36) is in fluid communication with the second space (42).
Abstract:
A sealing device which is used to seal a leak test aperture in an ECU. The sealing device is selectively disposed in the leak test aperture, and an inner surface is formed as part of the leak test aperture. The sealing device has a first portion, and a second portion connected to the first portion. The sealing device is press-fitted into the leak aperture such that the first portion is in contact with the inner surface, securing the position of the sealing device in the leak test aperture, and the second portion is also in contact with the inner surface to prevent moisture and debris from passing through the leak test aperture. The second diameter is larger than the first diameter such that the second diameter of the second portion applies a pressure to the inner surface of the leak test aperture, forming a seal.
Abstract:
A scavenger pump seal (13) and radial shaft seal (11) assembly therewith are provided. The scavenger pump seal includes an inner case (26) configured for fixed attachment to a shaft (12) for conjoint rotation with the shaft and an outer case (30) configured for fixed receipt in a housing in which the shaft rotates. The inner case has an innermost wall (32) sized for a press fit on the shaft and an outermost wall (34). An absorbent member (28) is fixed to the inner case with the outermost wall overlying the absorbent member, thereby preventing the absorbent member from moving radially outwardly. The outer case has an outermost wall sized for fixed receipt in the housing (15), and facilitates preventing the egress of oil to the external environment.
