20090067919 | Quick connect coupling - A quick to connect and quick to disconnect fluid coupling has a clip, a male portion having an annular groove adapted to receive the clip, a female portion, and a sealing element. The female portion has a dual function frustoconical portion adapted to compress the sealing element during joinder of the male portion with the female portion as well as to compress the clip into the annular groove in preparation of separating the male portion from the female portion. Further, a sleeve is slideably placed about the male portion and adapted to capture the clip compressed within the annular groove. | 03-12-2009 |
20100102974 | Diagnostic and response systems and methods for fluid power systems - Diagnostic and response systems and methods for a fluid power system acquire data from pressure and temperature sensors disposed in the fluid power system, analyze the data in a failure algorithm to build a history of cumulative damage to hoses in the fluid power system, communicates an indication of potential imminent hose failure to a central location when a level of the cumulative damage indicates imminent failure of a hose, analyze the information at the central location to determine an appropriate response, and transmit information about the fluid power system, including location, and identification of the hose about to fail to a response unit. The response unit responds to the location and replaces the component prior to failure, or the communication might include information that the hose has failed, such that the response unit replaces the failed hose to return the fluid power system to normal operation. | 04-29-2010 |

20100123309 | Crimpable or swageable fluid power ferrules couplings, systems and methods employing torque communication - A hose end coupling comprising a unitary one-piece stem having an exterior barb end portion and an exterior ferrule interface portion, with a unitary one-piece radially crushable ferrule disposed over the stem, with a crushable socket portion disposed about the barb end portion, a deformable attachment portion disposed about the ferrule interface portion, and a torque communication portion defined between the socket portion and the attachment portion. The socket portion may retain a “C” shaped insert, one or more coiled inserts, or a plurality of stacked inserts, for gripping a hose end and the socket portion might define a lip, with a seal disposed in the socket portion between the insert(s) and the lip. Some embodiments of a “C” shaped insert define inner-circumferential teeth and corresponding outer-circumferential depression indentions. | 05-20-2010 |

20100140926 | CRIMPABLE OR SWAGEABLE FLUID POWER FERRULES, COUPLINGS, SYSTEMS AND METHODS EMPLOYING TORQUE COMMUNICATION - A hose end coupling unitary, one-piece radially crushable ferrule has a crushable socket portion, a deformable attachment portion, and a work hardened torque communication portion defined between the socket portion and the attachment portion. The torque communication portion may be formed in the unitary one-piece radially crushable ferrule, contiguous with the socket portion and the attachment portion. Corners of the torque communication portion may be strengthened and/or the torque communication portion work hardened by disposing a die set about the formed torque communication portion and pressing the torque communication portion into the die set, strengthening corners of the torque communication portion and work hardening the torque communication portion. A mandrel having a desired internal shape of the torque communication portion may be deployed inside the torque communication portion during pressing. | 06-10-2010 |
20110121562 | Hybrid tube connector port - A hybrid port comprising a bore having a diameter, a first tapered surface having a cone angle α in the range of approximately 37° to approximately 45°, a second tapered surface having a cone angle β of approximately 12°, the first tapered surface disposed immediately proximate to the bore, and a threaded inner surface disposed axially between the first tapered surface and the second tapered surface. | 05-26-2011 |
20110309613 | Crimped or swaged couplings for cable reinforced hoses - A hose coupling for fitment to an end of a cable reinforced hose comprises a unitary stem having a cable trap groove portion having an outside diameter greater than an inside diameter of a tube of the hose and less than an inside diameter of the hose with the tube skived from the hose. A unitary ferrule defines at least one cable trap rib corresponding to the cable trap groove and having an inside diameter less than the outside diameter of the cable reinforced hose and greater than an outside diameter of the hose with material covering the cable skived from the hose. The groove width is at least the width of the rib plus twice the diameter of cable reinforcing the hose. Epoxy may be disposed between the hose tube and the stem for sealing or injected between the ferrule and the stem permeating the cable. | 12-22-2011 |

20140345738 | HOSE BURST SUPPRESSION SLEEVE SYSTEM - A protective suppression system including one or more sleeves of expansion coil of energy-absorbing material wrapped around a hose and a blanket which can be wrapped loosely around the wrapped hose. The longitudinal edges of the blanket fasten together to form a protective cylindrical tube, and can be joined end-to-end with one or more additional blankets to extend the protective tube to a desired total length. The system thus can provide improved safety to personnel and the environment by shielding a hose under pressure to suppress bursts, block leaks and by redirecting or channeling test fluids and cleaning fluids. | 11-27-2014 |
