Abstract: Coupling device (60) for mechanically and hydraulically coupling a fuel injector (20) to a fuel rail (18) of a combustion engine (22), the fuel injector (20) having a central longitudinal axis (L) and an injection nozzle (31), having a fuel injector cup (32) being designed to be hydraulically coupled to the fuel rail (14) and to engage a fuel inlet portion (24) of the fuel injector (20), and a spring element (36) being part of the fuel injector (20) and being designed to be in a snap-in engagement with the fuel injector cup (32) to retain the fuel injector (20) in the fuel injector cup (32) in direction of the central longitudinal axis (L) facing towards the injection nozzle (31).

Abstract: A leak detection feature for a fluid conduit. The leak detection feature facilitates the monitoring of fluid leaks at the interface of two adjoining conduit flange fittings. An embodiment of a flange fitting with a leak detection feature for a fluid conduit having an opening. The flange fitting includes a flange body around the opening of the fluid conduit, a leak detection passageway formed in the flange body, and a leak detection port formed in the flange body. The flange body has a sealing face surface configured to mate with a cooperating flange fitting, and the leak detection passageway terminates at the sealing face surface. The leak detection port is in fluid communication with the leak detection passageway, and the leak detection port is configured for fluid communication with a leak sensing apparatus.

Abstract: A plug-type connector for pipelines, having a first and a second connection end, with a first connection end being in the form of a first support body, the first support body being provided with a closure ring, the closure ring and the first support body forming an annular space for accommodating a pipe end, and for securing the pipe end, which is inserted into the annular space in a clamping manner, against axially acting withdrawal forces. The plug-type connector is distinguished in that the closure ring has at least one latching projection or latching recess with which the clamping ring can be axially secured.

Abstract: A quick connector coupling assembly comprising a conductive connector body, a tubular male member with an upset, and a primary retainer. The primary retainer releasably secures the male member within the connector body. The primary retainer body includes a pair of spaced legs connected by a cross member. The retainer body includes a conductive insert with contact surfaces exposed at the retainer legs to contact the male member and at the cross member to contact the connector body.

Abstract: An electrical fitting in the form of a connector or coupler for connecting an electric metal tube to an electrical box or panel or to one another. The fitting includes a body having an inlet end portion, an outlet end portion and a bore extending therethrough. An unidirectional locking device is disposed in an outermost chamber and a sealing washer disposed in an intermediate chamber. A split ring having an angularly bent leading end is provided with a series of offset circumferentially spaced unidirectional gripping tangs. The locking device may also be provided with a series of tube support tangs at the trailing end. Also, the locking device includes a tang forming an electrical bonding or ground between tubes, locking device and connector body.

Abstract: A pipe coupling for joining pipe elements end-to-end is disclosed. The pipe coupling is formed of segments attached to one another circumferentially straddling the pipe elements. The segments are formed from sub-sections connected to one another end-to-end. Each sub-section has a surface region disposed to engage the outer surfaces of the pipe elements. Each surface region has a different radius of curvature from a surface region on a neighboring sub-section. The radii are selected so that when the coupling segments are deformed around the pipe elements, portions of surface regions of selected sub-sections contact the pipe elements, while portions of surface regions of those sub-sections between the selected portions remain in spaced relation away from the pipe elements. A constant and minimal torque is required to bolt the segments together as a result.

Abstract: A thread form is shown which is used to make a threaded pipe connection capable of being screwed together and subsequently unscrewed. A pin member is provided having external threads with stab flanks and load flanks and flat crests and roots for mating with the mating internal threads of a box member to make up a pipe connection. One of the stab or load flanks is made up of two facets and three radii. The other selected flank is made up of three facets and four radii, giving it irregular features forming a complex geometric profiles. The thread form can be used to form a premium threaded connection which is used with such tubulars as casing and tubing for oil, gas, water and waste disposal wells.

Abstract: A sealing arrangement for a hydraulic plug-in connection for use in particular in the motor vehicle industry for hydraulic clutch and brake systems is fitted on a hydraulic plug-in connection and has a socket and a plug-in fitting which can be connected thereto. The plug-in fitting is attached to a hydraulic tube. The plug-in fitting has a sleeve and a sealing element fixed thereto, which seals off the plug-in connection both from the hydraulic tube and from the exterior of the socket. The sealing element and the end of the sleeve which receives the sealing element are designed so as to be able to install the sealing arrangement without it being possible for the sealing element to be separated axially from the sleeve when the plug-in connection is released.
