摘要： An improved quick connect coupling is provided for releasably connecting a pair of conduits, such as ordinary garden hose. The coupling comprises interlocking male and female fittings adapted for respective connection to a pair of hoses, wherein the male fitting includes a male member with an external circumferential groove for axial alignment with a generally opposed pair of arcuate slots in a female member on the female fitting. A C-shaped retainer is carried about the female fitting and includes a central spring base supporting a pair of locking arms which terminate in free ends having axially projecting lock tabs at the radially inner edges thereof, wherein these locking arms extend through the arcuate slots to position the arm free ends in engagement with radially oriented cam surfaces on the female member. In a normal unstressed condition of the retainer, the radially inner edges of the locking arms including the lock tabs extend into the male member groove to lock the coupling. When the coupling is subjected to water pressure, slight axial displacement of the male and female fittings move the lock tabs into locking engagement with the inner diameter surface of the female fitting thereby preventing retainer expansion and resultant inadvertent coupling disconnection. When the water pressure is turned off, however, the retainer spring base can be pushed radially inwardly to displace the locking arm free ends along the cam surfaces and outwardly from the male member groove to unlock the coupling.
摘要翻译：提供了一种改进的快速连接联接器，用于可释放地连接一对导管，例如普通花园软管。联接器包括适于相应地连接到一对软管的互锁公接头和阴配件，其中阳配件包括具有外周槽的阳构件，用于与阴配件上的阴构件中的大致相对的一对弧形槽轴向对准。 C形保持器围绕阴配件承载并且包括支撑一对锁定臂的中心弹簧座，该锁定臂终止于其径向内边缘处具有轴向突出的锁定突片的自由端，其中这些锁定臂延伸穿过弓形槽至将臂自由端定位成与雌性构件上的径向定向的凸轮表面接合。在保持器的正常无应力状态下，包括锁定突舌的锁定臂的径向内边缘延伸到阳构件槽中以锁定联接器。当联轴器受到水压时，阳型和阴型配件的轻微轴向位移将锁定片移动到与阴型配件的内径表面锁定接合，从而防止保持器膨胀并导致无意的联接断开。然而，当水压被关闭时，保持器弹簧座可以被径向向内推动，以沿着凸轮表面移动锁定臂的自由端并且从阳构件槽向外移动以解除联接。

摘要： Method and apparatus for establishing a seal across the annulus between two concentric rigid members to seal the annulus against large fluid pressures. A specially formed seal ring, advantageously of low carbon steel in the annealed state, is preliminarily inserted into the annular space between two concentrically opposed surfaces, then forced further into that annular space to force the sealing ring, with accompanying plastic deformation of a portion of the ring, into sealing engagement with both of the concentrically opposed surfaces.

摘要： A coupling includes at least one thin-walled sleeve which forms an axially extending defining wall of a substantially annular chamber. The chamber is arranged to be supplied with a pressure medium to elastically deform said sleeve in a radial direction into clamping engagement with a surface on an element which is to be connected to the coupling, the shape and dimension of said surface substantially corresponding to the shape and dimension of a surface on the sleeve remote from said chamber. The chamber has extending therefrom a channel arrangement which is arranged to cooperate with coupling-release means which can be activated by relative movement between said surfaces, or by a given torsional deformation thereof, to a state in which pressure medium can flow through said channel arrangement from said chamber to relieve the chamber of pressure acting therein.

摘要： A leakage preventive mechanism for flexible hoses through which is transferred fluid under a high pressure is disclosed. The mechanism comprises a rib made integral with a nipple portion of a nipple flange and circumferentially extending around said nipple portion. An end of a reinforcing layer embedded in the flexible hose passes over the rib and is wrapped around a bead wire arranged near the rib to form an inclined turn-back portion. A pair of rings are urged against the inclined turn-back portion of the reinforcing layer by means of bolts, whereby the inclined turn-back portion of the reinforcing layer functions as a packing for preventing the fluid from passing over the rib.

摘要： A coupling for connecting a supply conduit to a rigid or flexible extension tube, designed to carry a fluid under pressure, comprises a cylindrical housing having one end wall fastened to the conduit and another end wall formed with an opening for the insertion of an extremity of the tube. The inserted tube extremity is closely surrounded, within the housing, by one or more dished springs which can be deformed under axial pressure from an adjoining annular thrust member when the tube is filled with fluid; the pressure of the fluid may act upon the thrust member through an elastic ring, embracing the tube extremity which shifts relatively to the housing under such pressure, or directly through a gap behind that member which then operates as a piston forming a socket for the tube. The dished spring or springs are peripherally subdivided into coherent ring segments by radial slits facilitating the deformation of the spring which, by contracting under the applied axial pressure, grips the tube and prevents its extraction from the housing; this gripping action may be maintained, after reduction of the fluid pressure, by an indexing of the thrust member in its axially shifted position. Decoupling is possible by a reverse shifting of the tube to relax the dished spring or springs.

摘要： A coupling member for building into the end portion of a hose. The coupling member includes a portion which extends into the bore of the hose body and has one or more annular protuberances extending around the exterior surface. At least one notch extending into one of the protuberances provides a seal to prevent the flow of the fluid passing through the hose from leaking between the outer surface of the coupling member and the hose bore.
