Abstract: 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.

Abstract: A transportable test system having a control room module, a first IMR test module, and a second IMR test module. The test modules may have fasteners that permit assembly into a unitary package of predetermined overall dimension (i.e. size and shape) such as a standard shipping container dimension. A first IMR test module may have a clean fluid provider and/or supply reservoir, and a second IMR test module may have a used fluid collector and/or collection reservoir. The system may include pressurization, hose restraint, fluid containment, module stabilization/mobilization, lifting, cleaning, and control subsystems.

Abstract: 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.

Abstract: 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.

Abstract: 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 stein, 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.

Abstract: A threaded adapter is part of a quick-to-connect and quick-to-disconnect flexible hose coupling system. The adapter may provide a low-profile securement and seal between the port and the stem portion of the quick connect coupling. The adapter in combination with the fluid valve block orifice provides a seal that is further down in the valve block than the location of seals provided by other fluid couplings. Without relying on wrenching flats, the adapter also provides effective access to the hoses for repair and therefore is a cost saving device. The adapter may be a safe, reliable, easy to connect and disconnect component in a hydraulic system and is adaptable to accommodate any coupling including those in high and low pressure fluid and other systems.

Abstract: A hose coupling for fitment to an end of a cable reinforced hose includes 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.

Also, the sleeve may radially retain the clip, compressed in an annular groove of the stem, and/or the sleeve abutting the clip may stabilize the clip and axially align the clip with the stem, for insertion of the stem into the port.

Abstract: A connector includes a housing disposed in conjunction with a pressurized vessel and sprung valve assembly and a stem to be inserted into the housing in two stages. The stem is retained in the housing in the first stage and the stem activates the valve to release the pressurized fluid in the second stage. The connector employs a two-stage retaining mechanism that includes a clip retained in a groove defined in an interior wall of the housing, a lower groove and an upper groove formed into an exterior of the stem. The clip is disposed in the lower groove and the housing groove in the first stage; and in the upper groove and the housing groove in the second stage. The stem defines a stem stop that contacts an assembly setting mechanism upon completion of the first stage. The assembly setting mechanism is removed to allow the second stage.
