    摘要: A pipe coupling device includes a joint body, a C-shaped retaining ring that includes a flange part radially protruding from an outer peripheral surface of the retaining ring, a pressing plate that includes a recessed part configured to house the flange part, and includes a front wall configured to face a rear end of the flange part. The joint body, the retaining ring, and the pressing plate are coupled together in an axial direction. The flange part has a substantially rectangular shape extending along the axial direction, and an inclined surface is formed on at least one of the rear end and the front wall. An inner end of the inclined surface is positioned closer to the joint body than an outer end thereof. The inner end is closer to a center axis of the joint body than the outer end. A gap is formed between the rear end and the front wall.

    摘要: A quick coupling for the flexible tube supplying seeds from a storage bin to row crop units in a row crop seed planter. The quick coupling has an outer annular element with a bayonet connection and a central bore which receives an annular insert having two arcuate sections and holding the flexible tube in place through barbs. The inserts are removable from the outer annular coupling by means of a detent at which point the arcuate sections may be easily removed from the flexible tube.

    摘要: A hose end fitting that comprises an annularly corrugated imperforate metal tube, a fitting member fixed to an end of the tube, and, first and second resiliently compressible sealing members. The metal tube has axially spaced apart outer corrugation peaks and axially spaced apart inner valleys, each valley interposed between two of the peaks. Adjacent peaks and valleys are connected together by radially extending tube walls. The fitting member comprises a fitting body defining a through opening, a seal seat surrounding and extending outwardly from the through opening, and a tube compressing extension projecting from the fitting body. The tube compressing extension resiliently compresses the tube so that the first sealing member is resiliently engaged between the seal seat and the tube end to prevent leakage from within the hose while the second sealing member is resiliently compressed between adjacent inwardly extending tube walls and sealingly engages at least one tube wall and a fitting wall to block fluid leakage from outside the hose into the space between the sealing members.

    摘要: An end fitting for a composite tube used in high pressure hydraulic systems. The tube includes a composite matrix wrapped around a metal liner. The fitting includes an inner sleeve having a plurality of holes with pins therein extending into the matrix for securing the sleeve to the matrix. An outer sleeve fitting over the inner sleeve retains the pins within the holes, and the inner sleeve prevents the outer sleeve from sliding off the end of the tubing. A forward inner sleeve or ring encloses the end of the matrix and is also surrounded by the outer sleeve. A nut is retained on the outer sleeve for joining to a connector having an end surface which mates with the end of the liner flared against the end ring.

    摘要: A hose coupling which has an integrally moulded lip which has an innermost surface defining a frusto-conical shape and a portion of reduced thickness to provide for pivoting freedom of the lip to effect both a grip and seal of a hose that can be inserted therethrough. The lip has axially extending tails which are segmented allowing for expansion or contraction as necessary of the lip but providing a limit to the pivotal freedom of such lip.

    摘要: A coupling sleeve (3) pushed onto the plastic pipe (1) and provided with barbs (3a) is drawn over a driving shoulder against the connecting piece (2) by a union nut (4). The opened-out pipe end (1a) is clamped between a curved end face of the connecting piece (2) and the coupling sleeve (3). Possible leakages caused by the flow of the pipe material are prevented by a spring (6), and the pipe (1) is prevented from turning during assembly by a sliding ring (5).The device used for assembling the pipe connection has grips (13) for fixing the pipe in position with a toggle lock (16) and a press ring (26), which can be displaced in sliding manner on a stop (25) acting as a centering arbor, and can be actuated by a hand lever (31). With only a few manipulations, the coupling sleeve (3) can be pushed onto the centrally held plastic pipe (1).Owing to the omission of the supporting sleeve required hitherto, the through-flow cross-section of the plastic pipe (1) is not reduced by the installation of this pipe connection. Heating up the end of the plastic pipe is no longer necessary during assembly. The pipe connection, which can be made cost effectively, is uncomplicated in its construction and absolutely liquid-tight.

    摘要: A union device comprises a body having an inner bore communicating with an enlarged annular opening in a face of the body. A separate annular piece is secured in the opening with a press-fit by means of an external barb on the piece which opposes removal of the piece. The piece has an oppositely directed internal annular barb which engages in the outer surface of the end of a press-fitted flexible tube to tightly secure the tube without constricting its inner passageway which communicates with said bore.
